Cara Membuat game sederhana menggunakan Greenfoot

noreply@blogger.com (4zherboth) — Sat, 24 Dec 2011 04:58:00 -0800

Ada banyak software atau aplikasi untuk membuat game, namun yang kali ini membahas tentang aplikasi Greenfoot, salah satu aplikasi pembuat game sederhana berbasis Java.

Langkah pertama ialah klik new di menu Scenario:

Buat game sesuai sekenario game yang dibuat misalkan petualangan si boy. dalam game ini berskenario terdapat seorang jagoan yang ingin menyelamatkan putri yang ditawan oleh penjahat dan game ini akan berakhir apabila si jagoan berhasil menyelamatkan putri dari tawanan penjahat .

Buat Base awal berupa Lokasi game berlangsung. untuk membuat dunia dimana game ini berlangsung klik new sub class di bagian world lalu akan tampil dialog seperti dibawah ini :

Kemudian beri nama untuk class world ini misal beri nama dengan class ” dunia” dan pilih background untuk dunianya . setelah itu beri ukuran dunia ini tempat game berlangsung pada sub class dunia yang telah dibuat.Ukuran dunia nya berbasis sumbu, sumbu X untuk horizontal, dan sumbu Y untuk vertikal.
Misalnya kita buat ‘dunia’ nya ber ukuran 200X100, dengan ukuran 3 pixel pergambar.
Lalu kita buat codingnya

Pertama klik di subclass ‘dunia’ nya, lalu klik open editor

Kita buat (200,100,5)
200 adalah lebar ‘dunia’ nya
100 adalah tinggi ‘dunia’nya
5 adalah ukuran piksel pergambarnya.

Setelah memasukkan codingnya, klik compile atau tekan tombol ctrl dengan k. jika sukses tampilannya akan seperti ini

Setelah itu kita buat si musuh, pertama klik ikon actor lalu pilih pilihan new subclass. subclass musuh ini kita beri nama snake. Lalu kita pilih gambar untuk si snake, setelah kita beri nama klik ok.

Sekarang kita buat si snake bergerak dari kiri ke kanan
Berikut ini codingnya:
kita tulis di bawah public void act.

public void act()
{s
etLocation(getX() + 1, getY());
}

keterangan:
getX+1 => berarti dia akan bergerak ke kanan, (+1)
getY() => berarti dia tidak akan bergerak dengan sumbu Y
setelah itu sperti biasa kita compile codingnya, jika compile nya berhasil maka akan tampil pesan seperti ini

Jika sudah selesai dengan semua coding perrgerakan musuhnya, kita akan membuat agar si musuh
bisa menembus batas si ‘dunia’ yang tadi. Caranya kita akan membuat coding tambahan di si musuh,
misalnya kita buat di si snake yang tadi.
Kita beri tambahan coding:

public void act()
{s
etLocation(getX() + 1, getY());
if(getX()==199)
{
setLocation(0,getY());
}

}
Keterangan:
if(getX()==199)
{
setLocation(0,getY());
}

jadi ketika si snake mencapai titik X 199, (ujung kanan si ‘dunia’)
si snake ini akan muncul di Lokasi X => 0 (ujung kiri si ‘dunia’)
Setelah itu, kita buat juga untuk musuh – musuh yang lainnya.
Jika bisa, lanjutkan, namun jika masih adaa error jangan dilanjutkan periksa kembali coding nya.
Setelah kita selesai dengan para musuhnya, sekarang kita akan membuat si ‘jagoan’nya.
Caranya sama seperti sebelumnya, klik di actor, lalu pilih new subclass dan beri nama jagoannya,
misalnya boy. Setelah itu pilih gambar untuk si boy. Sekarang kita akan membuat coding untuk
pergerakan si boy, caranya klik subclass boy lalu pilih open editor setelah itu kita buat codingnya
seperti dibawah ini :

if(Greenfoot.isKeyDown(”right”))
{
setLocation(getX()+1,getY());
}
Keterangan:

if(Greenfoot.isKeyDown(”right”)) jika → tombol “panah kanan” ditekan maka …
setLocation(getX()+1,getY()); → gerakan Actor kearah kanan 1 cell
Setelah itu di test, lalu buat codingnya juga untuk bergerak ke atas, ke bawah, dan ke kiri.
Kalau kita klik tombol Reset, semua actor nya hilang, untuk membuat semua actornya ada kembali
ketika mengklik tombol Reset, kita buka editor di ‘dunia’ nya
lalu masukkan coding seperti dibawah ini:

addObject(new boy,7,145);

lalu pasang juga musuh – musuh nya di ‘dunia’ nya.

Nah sekarang kita akan membuat coding untuk matinya si ‘boy’
caranya buka editor nya, lalu kita masukkan coding nya seperti ini :
snake a=(snake)getOneIntersectingObject(snake.class);

if(a!=null)
{
setImage(”tengkorak.png”);
Greenfoot.playSound(”kalah.wav”);
getWorld().removeObject(a);
Greenfoot.stopSimulation;
return;
}

Keterangan :

snake =nama class musuh
a = nama variabel, boleh bebas, namun untuk mempermudah kita gunakan a
setImage = untuk membuat Greenfoot memunculkan gambar, gambar nya harus ada di folder images
di folder scenarionya, untuk perintah setImage ini dapat menggunakan file dengan format .jpg
atau .png
Greenfoot.playSound = perintah untuk membuat Greenfoot memainkan suara, format file nya
harus .wav dan ada di folder sounds
getWorld().removeObject(a) = membuat variabel a (snake) hilang
stop; = membuat permainan berhenti
buat juga coding yang sama untuk menabrak musuh yang lainnya.

Sekarang kita buat Peluru untuk si ‘boy’
caranya buka editor si ‘boy’
Tambahkan coding diatas public void act()

private dunia pelor;

public voidaddedToWorld(World dunia)
{
pelor = (dunia) dunia;
}

private = variabel ini hanya dikenali di class yang bersangkutan (Prince)
dunia = nama class World
pelor = nama variabel (terserah tapi tidak boleh sama dengan nama Actor
public void addedToWorld(World dunia) = Tambahkan class pelor ke World
dunia = nama variabel baru
Lalu buat di dalam act (boleh paling atas atau paling bawah, yang akan memicu keluarnya
peluru, yaitu jika ditekan tombol x (jangan lupa cari suara dengan nama fire.wav)

if(Greenfoot.isKeyDown(”x”))
{
pelor.addObject(new Peluru1(), getX(),getY());
Greenfoot.playSound(”fire.wav”);}
if(Greenfoot.isKeyDown(”x”)) = jika ditekan tombol x
pelor.addObject(new Peluru1(), getX(),getY()); = akan keluar Object baru yaitu peluru
letakan sama dengan Actor/Object aktif (boy) berada.
Greenfoot.playSound(”fire.wav”); = munculkan suara fire.wav (file harus ada difolder sounds)
Setelah peluru bisa keluar atur agar pelurunya langsung bergerak, misal dari kanan ke kiri, buat
codingnya di Actor Peluru1
setLocation(getX()+2,getY());
Ternyata ada sedikit masalah yaitu peluru akan meninggalkan sisa dibelakang akhir background
untuk mengatasinya gunakan coding berikut:

if(getX()==199)
{
getWorld().removeObject(this);
return;
}

getWorld().removeObject(this); = hilangkan object ini
return; = kembali keawal (perintah sangat penting dipakai jika perintah diatasnya
menghilangkan object, jangan sampai ada perintah lain yang menggunakan Object yang
telah dihilangkan, jika itu yang terjadi akan muncul pesan error).
Peluru yang baru saja dibuat belum berfungsi apaapa
karena jika Musuh tertembak tidak mati/
hilang buat jika peluru terkena Musuh15
maka Musuh hilang dan peluru hilang dengan bunyi
ah, buat coding di Peluru1 atau Musuh1 contoh disini dibuat di Peluru1, masukan file die1.wav
Setelah semua bisa, bagaimana jika sang girl tertembak ?, buat sang girl mati dan
permainan berakhir. Buat coding di Princess dan isi dengan:

Peluru1 f=(Peluru1)getOneIntersectingObject(Peluru1.class);
if(f!=null)
{
Greenfoot.playSound(”die1.wav”);
setImage(”kalah.png”);
getWorld().removeObject(f);
Greenfoot.stopSimulation();
}

Buat coding peluru1 dan jangan lupa ganti arah geraknya jadi kekiri
…………..
//peluru bergerak dari kiri ke kanan
setLocation(getX()+1,getY());
if(getX()==199)
{
getWorld().removeObject(this);
return;
}

//jika snake terkena peluru
snake a=(snake)getOneIntersectingObject(snake;
if(a!=null)
{
Greenfoot.playSound(”die1.wav”);
getWorld().removeObject(a);
getWorld().removeObject(this);
return;
}
……………

Membuat Skor
Agar permainan lebih menarik buat skor, dengan ketentuan setiap membunuh 1 musuh maka
nilai akan bertambah 20 dengan pengurangan pada peluru 1 peluru 1
nilai
Langkahlangkahnya:
1. Buat Actor Nilai dengan gambar angka 0 (ambil dari folder contoh di baloons tepatnya
di ….. greenfoot/scenarios/balloons/images/Counter.png)
2. Masuk ke jendela coding pada Actor Nilai dan buat coding diatas Public void act
3.
private int angka = 0;
private int target = 0;
private String huruf;
private int panjangHuruf;

public Nilai(String depan)
{
huruf=depan;
panjangHuruf = (huruf.length() + 2) * 16;
setImage(new GreenfootImage(panjangHuruf, 24));
GreenfootImage gambar = getImage();
Font jenisHuruf = gambar.getFont();
gambar.setFont(jenisHuruf.deriveFont(24.0F));
gantiGambar();
}
private void gantiGambar()
{
GreenfootImage gambar = getImage();
gambar.clear();
gambar.setColor(Color.RED);
gambar.drawString(huruf + angka, 1, 18);
}

private int angka = 0; ==> variabel angka
Font jenisHuruf = gambar.getFont(); ==> ambil jenis huruf karena perintah ini
diatasnya harus ada import java.awt.Font
gambar.setFont(jenisHuruf.deriveFont(24.0F)); ==> gunakan huruf terbesar yaitu 24
dengan jenis font derive. 0F dibaca nol ef
gantiGambar(); ==> jalankan class gantiGambar
private void gantiGambar() ==> membuat class gantiGambar
gambar.clear(); = kosongkan gambar (angka 0 diawal)
gambar.setColor(Color.RED); ==> pakai tulisan warna Merah. Pilihan lainnya BLACK,
WHITE, RED, GREEN (penulisan harus huruf besar semua). Karena
perintah ini memanggil perintah java diatasnya harus dibuat import
java.awt.Color
gambar.fillRect(20, 4, 24, 16); ==> background tulisan disini tidak dipakai
gambar.drawString(huruf + angka, 1, 18); ==> tata letaknya tulisan dulu baru angkanya
3. Tambahkan dibaris kedua
dari atas dibawah import greenfoot.*;
import java.awt.Font;
import java.awt.Color;
4. Buka classWorld(dunia) lalu buat variabel diatas Public Adventure ()
Nilai skor = new Nilai(”Skor: “);
addObject(skor,35,280);
5. Tambahkan object dibawah perintah menambahkan object yang lain
6. Lihat hasilnya sudah munculkah tulisan Skornya ? jika sudah lanjut agar skor bertambah
jika musuh mati
buka kembali layar coding Nilai dan tambahkan coding yang setingkat dengan public/private
void.

public void tambah(int skor)
{
target += skor;
}
if(angka < b="”(Musuh2)getOneIntersectingObject(Musuh2.class);”" target ="”"> target)
{
angka;
gantiGambar();
}
lanjutkan dengan menambahkan coding pada World dunia, tambahkan dibawah coding
public void tambahNilai()
public void kurangiNilai()
{
skor.kurang(1);
}
Lakukan pemicunya pada actor Prince (pemicu yang mengeluarkan Peluru) syaratnya peluru
ditekan nilai langsung berkurang 1, buat coding di bawah playSound
((dunia) getWorld()).kurangiNilai();

panggil aksi → kurangiNilai yg berada di World dunia.
if(Greenfoot.isKeyDown(”x”))
{
pelor.addObject(new Peluru1(), getX(),getY());
Greenfoot.playSound(”fire.wav”);
((dunia) getWorld()).kurangiNilai();
}

Pemunculan Papan Skor
Satu urusan lagi, papan skor dengan rancangan jika boy bertemu girl papan skor akan
muncul dengan ucapan SELAMAT dengan nilai …… dan permainan berakhir.
Tambahkan Actor PapanSkor lalu buat codingnya, coding lengkapnya:
import greenfoot.*;
import java.awt.Color;
import java.awt.Font;
import java.util.Calendar;
/**
* @author (auvy)
* @version (1.0.0)
*/

public class PapanSkor extends Actor
{
public static final float besarHuruf = 48.0f;
public static final int lebar = 500;
public static final int tinggi = 300;
public PapanSkor(int skor)
{
bikinGambar(”SELAMAT”, “Skor Akhir: “, skor);
}
private void bikinGambar(String judul, String depan, int skor)
{
GreenfootImage gambar = new GreenfootImage(lebar, tinggi);
gambar.setColor(new Color(25, 5, 74, 160));
gambar.fillRect(0, 0, lebar, tinggi);
gambar.setColor(new Color(255, 255, 255, 50));
gambar.fillRect(5, 5, lebar10, tinggi10);
Font font = gambar.getFont();
font = font.deriveFont(besarHuruf);
gambar.setFont(font);
gambar.setColor(Color.GREEN);
gambar.drawString(judul, 60, 100);
gambar.drawString(depan + skor, 60, 200);
setImage(gambar);
}
}
Di Actor Nilai tambahkan coding yang setingkat dengan public void act()
public intnilaiAkhir()
{
return angka;
}
Di World dunia buat coding setingkat public void seperti ini:
public void selesai()
{ addObject(new PapanSkor(skor.nilaiAkhir()*5), 247,145);
}
Nilai akhir didapat dari jumlah skor dikalikan 5 da → n letakan di tengahtengah
Buat pemicunya di Actor boy atau girl (pilih salah satu), disini pakai girl
boy h=(boy)getOneIntersectingObject(boy.class);
if(h!=null)
{
((Adventure)getWorld()).selesai();
Greenfoot.playSound(”login.wav”);
Greenfoot.stopSimulation();
}

Happy Birthday Mary Blair 100th

Yes we briefly hehe strings attached ......

Wow already 5 days was not open blogs, knowing my monitor broken so I used my mom's monitor hahahahaha
Earlier when I open my web browser.
Humb ..... There is an awkward, visible from the initial window google
I think "Now there is a feast of what?". Then I hold the mouse in the direction of writing is usually Google
Ow it turns out now Mary Blair's birthday is the 100th
Yes, now I'll post about the biography and history.

Mary Blair (October 21, 1911 - 26 July 1978), was born with the name of Mary Robinson, was a leading American artist in producing art and animation for The Walt Disney Company,drawing concept art for movies like Alice in Wonderland, PeterPan, Song of the South and Cinderella. Blair also created the character designs for timeless attractions like It's a Small World at Disneyland, the party scene in El Tiempo del Rio in Mexicopavilion in Epcot World Showcase, and a very large mosaic in theDisney's Contemporary Resort. Some of his children's book illustration from the 1950s still be printed, such as I Can Fly by RuthKrauss. Blair is respected as a Disney Legend in 1991.

And this work of his :

Yes enough for today see ya.....
Uh almost forgot, happy birthday
Hopefully useful article

Tutorial on Key Generators

noreply@blogger.com (4zherboth) — Mon, 17 Oct 2011 03:26:00 -0700

Hallo All !

Now I will learn about key generator
Humb ...... I'm curious about the key generator so I am lookingbagaimanan how to create and the tools needed to make a key generator and this is the result :

Tools!

For tools you need a minimum of debugger like SoftIce for Windows (hence WinIce), and a C compiler with Dos libraries.

Content!

In this tutorial I will show how to make a key-gen for Ize and Swiftsearch. The protection that these programs use is the well known Enter-Name-and-Registration-Number method. After selecting 'register', a window pops up where you can enter your name and your registration number. The strategy here is to find out where in memory the data you enter is stored and then to find out what is done with it. Before you go on make sure you configure the SoftIce dat file according to the PWD tutorial #1.

Part 1: Scanline Swiftsearch 2.0!

Swiftsearch is a useful little program that you can use to search on the web. I will explain step by step how to crack it.

step 1. Start the program :)

step 2: Choose register from the menus. You will now get a window where you can enter your name and your registration number.

step 3: Enter SoftIce (ctrl-d)

step 4: We will now set a breakpoint on functions like GetWindowText(a) and GetDlgItemText(a) to find out where in memory the data that we just entered is stored. The function that is used by this program is GetDlgItemTexta (trial and error, just try yourself :) so, in SoftIce type BPX GetDlgItemTexta and exit SoftIce with the g command.

step 5: Now type a name and a registration number (I used razzia and 12345) and press OK, this will put you back in SoftIce. Since you are now inside the GetDlgItemTexta function press F11 to get out of it. You should see the following code:

lea eax, [ebp-2C] :<--- we are looking for this location

push eax

push 00000404

push [ebp+08]

call [USER32!GetDlgItemTextA]

mov edi, eax :<--- eax has the length of the string

and is stored in edi for later usage.

We see that EAX is loaded with a memory address and then pushed to the stack as a parameter for the function GetDlgItemTextA. Since the function GetDlgItemTextA is already been run we can look at EBP-2c (with ED EDP-2c) and see that the name we entered is there. Now we know where the name is stored in memory, normally it would be wise to write that address down, but we will see that in this case it wont be necessary.

So, what next? Now we have to allow the program to read the registration number we entered. Just type g and return and when back in SoftIce press F11. You should see the following code:

push 0000000B

lea ecx, [ebp-18] : <--So, ebp-18 is where the reg. number

push ecx : is stored.

push 0000042A

push [ebp+08]

call [USER32!GetDlgItemTextA]

mov ebx, eax : <--save the lenght of string in EBX

test edi, edi : <--remember EDI had the lenght of the

jne 00402FBF : name we entered?

We see that the registration number is stored at location EBP-18 , check it with ED EBP-18. Again, normally it would be wise to note that address down. Also we see that it is checked if the length of the name we gave was not zero. If it is not zero the program will continue.

Step 6: Ok, now we know where the data we entered is stored in memory. What next?

Now we have to find out what is DONE with it. Usually it would we wise to put breakpoints on those memory locations and find out where in the program they are read. But in this case the answer is just a few F10's away. Press F10 until you see the following code :

cmp ebx, 0000000A :<--remember EPX had the length of the

je 00402FDE : registration code we entered?

These two lines are important. They check if the length of the registration code we entered is equal to 10. If not the registration number will be considered wrong already. The program wont even bother to check it. Modify EBX or the FLAG register in the register window to allow the jump. Continue Pressing F10 until you get to the following code (note that the adresses you will see could be different) :

:00402FDE xor esi, esi :<-- Clear ESI

:00402FE0 xor eax, eax :<-- Clear EAX

:00402FE2 test edi, edi

:00402FE4 jle 00402FF2

:00402FE6 movsx byte ptr ecx, [ebp + eax - 2C] :<-- ECX is loaded with a letter of the name we entered.

:00402FEB add esi, ecx :<-- Add the letter to ESI

:00402FED inc eax :<-- Increment EAX to get next letter

:00402FEE cmp eax, edi :<-- Did we reach the end of the string?

:00402FF0 jl 00402FE6 :<-- If not, go get the next letter.

Well, we see that the program adds together all the letters of the name we entered. Knowing that ESI contains the sum of the letters, lets continue and find out what the program does with that value :

:00402FF2 push 0000000A

:00402FF4 lea eax, [ebp-18] :<-- Load EAX with the address of the reg. number we entered

:00402FF7 push 00000000

:00402FF9 push eax :<-- Push EAX (as a parameter for the following function)

:00402FFA call 00403870 :<-- Well, what do you think this function does? :)

:00402FFF add esp, 0000000C

:00403002 cmp eax, esi :<-- Hey!

:00403004 je 00403020

We see that a function is called and when RETurned ESI is compared with EAX. Hmm, lets look at what's in EAX. A '? EAX' reveals :

00003039 0000012345 "09"

Bingo. That's what we entered as the registration number. It should have been what's inside ESI. And we know what's inside ESI, the sum of the letters of the name we entered!

Step 7: Now we know how the program computes the registration code we can make a key-gen.

But we should not forget that the program checks also that the registration number has 10

digits.

A simple C code that will compute the registration number for this program could look like this:

#include <stdio.h>

#include <string.h>

main()

{

char Name[100];

int NameLength,Offset;

long int Reg = 0, Dummy2 = 10;

int Dummy = 0;

int LengtDummy = 1;

int Lengt , Teller;

printf("Scanline SwiftSearch 2.0 crack by raZZia.\n");

printf("Enter your name: ");

gets(Name);

NameLength=strlen(Name);

/* the for lus calculates the sum of the letters in Name */

/* and places that value in Reg */

for (Offset=0;Offset<NameLength;Offset=Offset+1)

{

Reg=Reg+Name[Offset];

}

/* the while lus calculates the lenght of the figure in */

/* Reg and places it in Lengt */

while (Dummy != 1)

{

if ( Reg < Dummy2 )

{ Lengt = LengtDummy ; Dummy =1;

}

else

{ LengtDummy=LengtDummy + 1; Dummy2=Dummy2*10;

}

};

printf("\nYour registration number is : " );

/* First print 10-Lengt times a 0 */

Lengt=10-Lengt;

for (Teller=1;Teller<=Lengt;Teller=Teller+1) printf("0");

/* Then print the registration number */

printf("%lu\n",Reg);

}

Case 2 Ize 2.04 from Gadgetware

Ize from Gadgetware is a cute little program that will put a pair of eyes on your screen which will

follow your mousepointer. It has a register function where you can enter your name and a registration

number. The strategy in this case is still the same : Find out where in memory the entered information

is stored and then find out what is done with that information.

Step 1: Start Ize. Chose register and enter a name and a number. I used 'razzia' and '12345'.

Sterp 2: Enter (CTRL-D) Softice and set a breakpoint on GetDlgItemTextA.

Step 3: Leave SoftIce and press OK. This will put you back in Softice. You will be inside the GetDlgItemTextA

function. To get out of it press F11. You should see the following code :

mov esi, [esp + 0C]

push 00000064

push 0040C3A0 :<--On this memory location the NAME we entered will be stored.

mov edi, [USER32!GetDlgItemTextA] :<--Load edi with adress of GetDlgItemTextA

push 00004EE9

push esi

call edi :<-- Call GetDlgItemTextA

push 00000064 :<-- (you should be here now)

push 0040C210 :<--On this memory location the NUMBER we entered will be stored

push 00004EEA

push esi

call edi :<-- Call GetDlgItemTextA

We see that the function GetDlgItemTextA is called twice in this code fragment. The first call has

already happened. With ED 40C3A0 we can check that the name we entered is stored on that location.

To allow the program to read in the number we entered we type G and enter. Now we are inside the Get-

DlgItemTextA function again and we press f11 to get out of it. We check memory location 40C210 and

we see the number we entered is stored there.

Now we know the locations were the name and the number are stored,we note those down!

Step 4: Ok, what next? We now know where in memory the name and the number are stored. We need to find out

what the program does with those values. In order to do that we could set breakpoints on those memory

locations to see where they are read. But in this case it wont be necessary. The answer is right after the

above code :

push 0040C210 :<--save the location of the number we entered (as a parameter for the next call)

call 00404490 :<-- call this unknown function

add esp, 00000004

mov edi, eax :<-- save EAX (hmmmm)

We see a function being called with the number-location as a parameter. We could trace into the function and see what it does, but that is not needed. With your experience of the Swiftsearch

example you should be able to guess what this function does. It calculates the numerical value of the registration number and puts it in EAX. To be sure we step further using F10 untill we are past the call and check the contents of EAX (with ? EAX). In my case it showed : 00003039 0000012345 "09".

Knowing that EDI contains our registration number we proceed:

push 0040C3A0 :<-- save the location of the name we entered (as a parameter for the next call)

push 00409080 :<-- save an unknown memory-location (as a parameter for the next call)

call 004043B0 :<--call to an unknown function

add esp, 00000008

cmp edi, eax :<--compare EDI (reg # we entered) with EAX (unknown, since the previous call changed it)

jne 004018A1 :<--jump if not equal

We see that a function is called with two parameters. One of the parameters is the location of the name

we entered. The other we dont know, but we can find out with ED 409080. We see the text 'Ize'.

This function calculates the right registration number using those two parameters. If you just want to

crack this program, you can place a breakpoint right after the call and check the contents of EAX. It will

contain the right registration number. But since we want to know HOW the reg. # is calculated we will trace inside the function (using T). We will then try to find out HOW the contents of EAX got in there.

Step 5: Once inside the interesting function you will see that we are dealing with a rather long function. It wont be necessary for me to include the complete listing of this function, because we wont need all of it to make our key-gen.

But in order find out which part of the code is essential for the computation of the right registration number, you have to trace STEP by STEP and figure out what EXACTLY is going on!

Afther doing this i found out that the first part of the function computes some kind of "key". Then this

"key" is stored in memory and in that way passed on to the second part of the function.

The second part of the function then computes the right registration number, based on this "key" AND

the name we entered.

The code that is essential and that we need for our key-gen is the following:

( Note that before the following code starts, the registers that are used will have the following values:

EBX will point to the first letter of the name we entered,

EDX will be zero,

EBP will be zero,

The "key" that we talked about earlier is stored in memory location 0040B828 and will

have 0xA4CC as its initial value. )

:00404425 movsx byte ptr edi, [ebx + edx] :<-- Put first letter of the name in EDI

:00404429 lea esi, [edx+01] :<-- ESI gets the "letter-number"

:0040442C call 00404470 :<-- Call function

:00404431 imul edi, eax :<-- EDI=EDI*EAX (eax is the return value of the the previous call)

:00404434 call 00404470 :<-- Call function

:00404439 mov edx, esi

:0040443B mov ecx, FFFFFFFF

:00404440 imul edi, eax :<-- EDI=EDI*EAX (eax is the return value of the previous call)

:00404443 imul edi, esi :<-- EDI=EDI*ESI ( esi is the number of the letter position)

:00404446 add ebp, edi :<-- EBP=EBP+EDI (beware that EBP will finally contain the right reg#)

:00404448 mov edi, ebx :<--these lines compute the lenght of the name we entered

:0040444A sub eax, eax :<--these lines compute the lenght of the name we entered

:0040444C repnz :<--these lines compute the lenght of the name we entered

:0040444D scasb :<--these lines compute the lenght of the name we entered

:0040444E not ecx :<--these lines compute the lenght of the name we entered

:00404450 dec ecx :<-- ECX now contains the lenght of the name

:00404451 cmp ecx, esi

:00404453 ja 00404425 :<-- If its not the end of the name , go do the same with the next letter

:00404455 mov eax, ebp :<-- SAVE EBP TO EAX !!!!

:00404486 shr eax, 10 :<-- EAX=EAX >>10

:00404489 ret

The above code consists of a loop that goes trough all the letters of the name we entered. With each

letter some value is calculated, all these values are added up together (in EBP). Then this value is stored

in EAX and the function RETurns. And that was what we were looking for, we wanted to know how EAX got its value!

Step 6: Now to make a key-gen we have to translate the above method of calculating the right reg# into a

c program. It could be done in the following way :

(Note : I am a bad c programmer :)

#include <stdio.h>

#include <string.h>

main()

{

char Name[100];

int NameLength,Offset;

unsigned long Letter,DummyA;

unsigned long Key = 0xa4cc;

unsigned long Number = 0;

printf("Ize 2.04 crack by razzia\n");

printf("Enter your name: ");

gets(Name);

NameLength=strlen(Name);

for (Offset=0;Offset<NameLength;Offset=Offset+1)

{

Letter=Name[Offset];

DummyA=Key;

DummyA=DummyA*0x15a4e35;

DummyA=DummyA+1;

Key=DummyA;

DummyA=DummyA & 0x7fff0000;

DummyA=DummyA >> 0x10;

Letter=Letter*DummyA;

DummyA=Key;

DummyA=DummyA*0x15a4e35;

DummyA=DummyA+1;

Key=DummyA;

DummyA=DummyA & 0x7fff0000;

DummyA=DummyA >> 0x10;

Letter=Letter*DummyA;

Letter=Letter*(Offset+1);

Number=Number+Letter;

}

printf("\nYour registration number is : %lu\n",Number);

}

Tutorial How To Download Torrent

noreply@blogger.com (4zherboth) — Sat, 8 Oct 2011 05:02:00 -0700

Yes Share a little about this torrent

Yesterday I want to download the book but why the format torrent er

I wonder why how the format torrent

I searched the internet about torrent.

Now,i know why using torrent

So I wanted to share my knowledge of torrent files

You definitely know the word "torrent". If a new hearing, he answered Hanay one, type C <space> D, becomes Cape 'dech, hahahahaha.

Torrent is actually a file extension of the BitTorrent protocol applications that run on Peer-to-Peer or better known by the term "p2p protocol", to download the torrent as well as downloading via http port, only difference there is on how to download the packet, if the http using a single ports on a single TCP socket and on the specified port (port 80), BitTorrent uses TCP sockets are different and also use a random port on each connection.

Then the most interesting part of BitTorrent is, srouce data or files downloaded not only taken from one source only as http, the current BitTorrent seeder (data suppliers) send a copy to one peer (client) then the other peer does not have to retrieve the data that need to seeder but from another peer that has the data needed, so that the peer did not need to take from the seeder, so-called peer-to-peer file sharing.

How to download TorrentIf you want to download something via torrent you can use a BitTorrent client like uTorre, Azureus or the other,simply download the file. torrent is in want and enter the BitTorrent Client application before the download process will be done by the BitTorrent Client, you can see the statistics of large data files, the number of peers, the number of seeders and others.

Slow when downloading??

If you find it slow to download via BitTorrent, you are wrong, statistics from an ISP shows bawhwa BitTorrent uses about 18% of the total Internet traffic on a broadband connection in 2004, the number is quite high.

Possibilities that occur when you download via BitTorrent is a little slow peers / seeders, many peers but no seeder amount to 5% the number of peers, you are behind a firewall (in the sense that you have a firewall blocking p2p traffic data), or also the port that you use for BitTorrent closed.

Usually if we are in the office or cafe mostly happens is that the closed ports for BitTorrent applications because we are in NAT.

In order to open ports for BitTorrent (officialy :6881-6889 port) then we do pelu `` Port-Forwarding to port to the computer that we use to download BitTorrent open.

So that I can give, if there is wrong, please corrections.

The Cause of Your Keyboard is Not Detected

noreply@blogger.com (4zherboth) — Thu, 22 Sep 2011 07:06:00 -0700

Now I will discuss about the cause of your keyboard is not detected

Yes the keyboard is a bit definitions:

The keyboard is a board that consists of buttons to type a sentence and other special symbols on the keys on the keyboard computer.Number of there are 104 key.Keyboard have in common form and function with a typewriter

The function keyboard is as one of the computer input devices

Uh, before I continue the storythere is little experience from me regarding the damage to the keyboard

Yesterday my keyboard is broken, can only typed up the letter "asd"

ouch ....I'm frustrated by weight, a task unfinished. Yes I am forced to use On-Screen Keyboard.
Humb ... yes too long writing life on-screen keyboard but that's what's important task is complete.

The next day the task is not collected, in my heart "Stand up to defend've hardly slept in was not collected, at least I've been working on". I asked my friend about my keyboard.

My friend said "try to check whether the keyboard cable is installed is correct, if still not detected you I mean keyboard problem, try changing your keyboard, if it has been replaced but the problem persists then it is most likely damaged in the keyboard port on your motherboard, If it has a new keyboard replaced but still not detected also try to replace it with a usb keyboard and if not detected also means there is something wrong in the Windows system. "

So basically if you have problems try to check the keyboard:

-Is your keyboard is plugged in correctly

-Try to buy a new keyboard

-If it has been replaced but the problem persists then it is most likely damaged in the keyboard port on the motherboard

-If it's in a New Keyboard Replace remain undetected but Also Try to Replace the Keyboard USB

-And if not detected also means there is something wrong in the Windows system Buddies
Well it's a bit about the keyboard

Ow yes almost forgot, the end of the story above is giving me a new keyboard, and I am happy to go back to typing with fingers

Graduate

There may be among friends who often see the display picturebios, safe mode, the installation process, the process of loading windows, there are some friends who asked about how to capture,or record sreenshot view. If you've logged into windows, then display on the screen can be recorded using printscreen command, but what about the view before logging into Windows,the bios display, and the process of installing windows.

There are several software that can be used, one of which is Microsoft Virtual PC 2007, I have installed this software on windows 7 (runs well), but have not tried in Windows XP.

For the record display or display windows install process DOS, first open the windows and then open the application Microsoft VirtualPC, will open a window (window) the new Virtual PC, click the Start button or Run Virtual PC and then during the boot process in the Virtual PC will then press the delete button page appears bios, setboot from CD, insert the CD (eg CD Windows boot CD, etc.) that can boot to the CD-Drive, then while booting in Virtual PC hit enter, it will appear as when you are installing the software.

For the record, you simply press the printscreen button on your keyboard.
Examples of the view that I recorded using Microsoft Virtual PCcan be found here
record (screenshots) display dos

Make friends who want to try, the trial software can be found atindowebster or microsoft site.

There are several requirements for Microsoft's Virtual PC softwareto function on a computer, ie processor must support Virtualization Technology, if using an Intel processor can be seen here captionIntel Virtualization Technology, if you make use of AMD processorscan be seen testimony in AMD Virtualization Technology

Trojan How it Works

noreply@blogger.com (4zherboth) — Wed, 7 Sep 2011 06:40:00 -0700

Trojans get into the computer via the two parts, the client and the victim server.When unnoticed running computer, the attacker will

use the client to connect to the server and start using the Trojan.
Trojans can work well on the type of protocol TCP / IP, but someTrojans can also use the UDP protocol properly, when the serverstarts running, the Trojan generally try to hide somewhere in thecomputer system, then start "listening" in some ports to performconnection, modify the registry, or using other methods ie withautostarting method. The important thing is known by the attackerknows the victim IP addresses to connect computers to the victim'scomputer.

Many variants of the Trojan has the ability to send the victim's IP address to the attacker, eg ICQ or IRC.Hal media was used onvictims who have a dynamic IP address, which means every time they connect to the internet to get a different IP address. For userswho make use of Asymmetric Digital Suscriber Line (ADSL),always use a fixed IP address (static) so easily identified and easy to connect to the computer attackers.

Most of the Trojans use the method auto-starting, yaituTrojan willautomatically komptuer active when first turned on. Although thecomputer is turned off and then turned on again, Trojanmampuworking again and the attacker can regain access to a victim'scomputer.

Understanding Trojan

noreply@blogger.com (4zherboth) — Wed, 7 Sep 2011 06:39:00 -0700

The term Trojan horse (Trojan Horse) comes from the Greek methodology in time of war troya.In war, army against army greek greek troya.Troops have besieged city of Troy for ten year.But, because the Trojan royal army strong enough, it is difficult for the Greek army to defeat them.

Finnaly, Greek troops make strategy by making a giant horse made of wood.The horse is quite unique, in which there is a cavity, so that it can be filled by forces Yunani.Troops Greek temple - temple retreat, and while providing a giant wooden horse gifts to the kingdom of Troy with the help of a Greek named sinon espionage, trojans towns people convinced to accept the prize is a giant wooden horse and put it into town and in the evening, the Greek troops who had been inside the cavity of the wooden horse came out, then open the gates of the kingdom trojans to enter other Greek troops who had long waited to attack the city Troya.dengan way, the city of trojans can be controlled by the greek.

For those readers who never watched the movie troy .. probably already know about the story on the kingdom's fun .. right?? Those who do not watch the game looking .. .. hehehhee.Has inspired a short story on the hacker to create the "intruders" into the computers of other people who called the former Trojan horse.Trojan is a gift to the kingdom of Troy at this point in the term it has to do with computer security issues that can get pretty serius.Trojan to the computer in several ways and from various sources that are less trusted on the internet or from other people.As with any virus, Trojan number progressively increased .It is because the hacker or Trojan program makers always do experiment to develop.

Trojan does not have an active period as antivirus.artinya update Trojan will always be there and will never run out during yet eradicated.There are many things that were developed by a programmer that programs are not detected by anti virus or Trojan scanner.Programer always do experiment to create a unique Trojan with functions - new functions with the encryption method that is more good technical.Way Trojans can appear anywhere and anytime , either on any operating system, and a variety of platforms.One indication of computers infected by the Trojan can be described as the following example:By the time the computer is connected to the Internet, for example during chat or at the time and examine the incoming email, hard work within a busy or slow.Whereas, we're not running the application programs that are large or not is to download something that requires hard disk spin long enough, events including the strange events that spy Trojan suspected infiltration.
