如何開始 cocos2d-x Visual Studio 新專案

2012-05-29T23:50:00.003-07:00

不是英文苦手的請參考 Cocos2d-x Application Wizard for Visual Studio User Guide

0.請先安裝好Visual Studio 2008 、2010 (廢話) 沒有序號的用這個頂著先

1. 下載 cocos2d-x sourse code
      寫這文章時最新版本為 ccocos2d-1.0.1-x-0.13.0-beta @ Mar 29, 2012
    (1) 直接下載
    (2) git : https://github.com/cocos2d/cocos2d-x

2. 下載後，找個好目錄解壓縮，先建置一次，有兩種方式
   (1)

(2)

人品好就可以在 \Debug.win32 或 \Release.win32目錄下找到 HelloWorld.exe 、tests.exe

運行畫面

3.安裝精靈

4.使用精靈創建新專案

5.依所選的功能
   (1)把原始專案 copy 到相對資料匣下
   (2)把 lib、dll copy 到 Debug.win32 或 Release.win32 下
   (3)把圖放到到 Debug.win32 或 Release.win32 下

6.建置

XCode 4 says “finished running ” on the device , but nothing happens　,iPhone 3g　真機測式

2011-11-08T20:06:00.000-08:00

最近借到一隻　iphone 3G　來玩玩
結果沒辦法在執行在Device上

情怳是～編譯後在 title 上出現　finished running "程式"　　on ”裝置名稱”，
滿心期待的等了３０秒後～確一直沒有出現在裝置上
重覆試了幾次結果也是一樣

只好上網google了
最後找到一篇討論～～　link

解法一：
Project -> Clean then Project -> Run again

解法二：
修改　　architectures　　armv7　＝＞　　armv６

而且我遇到的看來因該是要解法二了，
因為這專案新創的、因該沒有做到個設定
設定方法

OK~～終於出現在　iphone 3G 上面了

(iOS)如何新增AdMob (圖文教學）

2011-10-12T20:16:00.000-07:00

前言:免費的應用程式記得設計區塊給廣告用來增加收入吧

1. get admob acount 申請admob申號

2.get publish id
(1)點選新增網站/應用程式

(2)choice iPhone / iPad　跟樣式

(3) get publish id 發佈商ID.

3. download SDK
Google AdMob Ads SDK for iOS

4. get code
You can download an
example project

or see see Google AdMob Ads iOS Fundamentals to code

5.define MY_BANNKER_UINT_ID as your AdMob Publish ID

6. build

PS:第一次執行是看不到廣告的　，要等至少2分鐘才會接收成功

７not wait to test 不想等可以這麼做
find



[bannerView_ loadRequest:[GADRequest request]];

replace



[GADRequest *testRequest = [GADRequest request];

testRequest.testing = YES;

[bannerView_ loadRequest:testRequest];

so you can see

最後不負責任預測～不久之後也許會改～因為目前AdMob被Google買下不久而已目前因該整合中

//

NSFileManager *fileManager = [NSFileManager defaultManager];

NSMutableDictionary *plistDict;

if ([fileManager fileExistsAtPath: filePath]) //檢查檔案是否存在

{

plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:filePath];

}else{

plistDict = [[NSMutableDictionary alloc] init];

UIRequiredDeviceCapabilities 指定程序需要那些設備

2011-08-30T20:15:00.000-07:00


	Key	說明
	telephony(電話）	Include this key if your application requires (or specifically prohibits) the presence of the Phone application. You might require this feature if your application opens URLs with the tel scheme
	wifi	Include this key if your application requires (or specifically prohibits) access to the networking features of the device.
	sms	Include this key if your application requires (or specifically prohibits) the presence of the Messages application. You might require this feature if your application opens URLs with the sms scheme.
	still-camera	Include this key if your application requires (or specifically prohibits) the presence of a camera on the device. Applications use the UIImagePickerController interface to capture images from the device’s still camera.
	auto-focus-camera	Include this key if your application requires (or specifically prohibits) auto-focus capabilities in the device’s still camera. Although most developers should not need to include this key, you might include it if your application supports macro photography or requires sharper images in order to do some sort of image processing.
	front-facing-camera	Include this key if your application requires (or specifically prohibits) the presence of a forward-facing camera. Applications use the UIImagePickerController interface to capture video from the device’s camera.
	camera-flash(相機閃光燈)	Include this key if your application requires (or specifically prohibits) the presence of a camera flash for taking pictures or shooting video. Applications use the UIImagePickerController interface to control the enabling of this feature.
	video-camera	Include this key if your application requires (or specifically prohibits) the presence of a camera with video capabilities on the device. Applications use the UIImagePickerController interface to capture video from the device’s camera.
	accelerometer(加速度計)	Include this key if your application requires (or specifically prohibits) the presence of accelerometers on the device. Applications use the classes of the Core Motion framework to receive accelerometer events. You do not need to include this key if your application detects only device orientation changes.
	gyroscope(陀螺儀)	Include this key if your application requires (or specifically prohibits) the presence of a gyroscope on the device. Applications use the Core Motion framework to retrieve information from gyroscope hardware.
	location-services(定位服務)	Include this key if your application requires (or specifically prohibits) the ability to retrieve the device’s current location using the Core Location framework. (This key refers to the general location services feature. If you specifically need GPS-level accuracy, you should also include the gps key.)
	gps	Include this key if your application requires (or specifically prohibits) the presence of GPS (or AGPS) hardware for greater accuracy when tracking locations. If you include this key, you should also include the location-services key. You should require GPS only if your application needs more accurate location data than the cell or Wi-fi radios might otherwise allow.
	magnetometer(磁力儀)	Include this key if your application requires (or specifically prohibits) the presence of magnetometer hardware. Applications use this hardware to receive heading-related events through the Core Location framework.
	microphone	Include this key if your application uses the built-in microphone or supports accessories that provide a microphone.
	opengles-1	Include this key if your application requires (or specifically prohibits) the presence of the OpenGL ES 1.1 interfaces.
	opengles-2	Include this key if your application requires (or specifically prohibits) the presence of the OpenGL ES 2.0 interfaces.
	armv6	Include this key if your application is compiled only for the armv6 instruction set. (iOS v3.1 and later.)
	armv7	Include this key if your application is compiled only for the armv7 instruction set. (iOS v3.1 and later.)
	peer-peer	Include this key if your application requires (or specifically prohibits) peer-to-peer connectivity over Bluetooth. (iOS v3.1 and later.)

提交app時可以在info.plist設置　

This generally means that another instance of this process was already running or is hung in the debugger

2011-08-23T01:33:00.000-07:00

今天在測式時　crash之後
再編譯時就一直出現Error

This generally means that another instance of this process was already running or is hung in the debugger

實體機上沒有看到在跑任何程式丫～

但就是重編不了～

最後是裝置關機重開才行～

iOS設備內存硬體

2011-08-22T02:04:00.000-07:00


設備	CPU	螢幕顯示	內存
1代	412MHz	480X320	128MB
iPhone3G	412MHz	480X320	128MB
iPod Touch	532MHz	480X320	128MB
iPhone3GS	600MHz	480X320	256MB
iPad	1GHz	1024X768	256MB
iPhone4	1GHz	960X640	512MB
ipad2	1GHz 雙核心 Apple A5	1024X768	512MB

如果要寫iphone程式，最好以128MB內存來思考，而且還要扣iOS系統佔用的
除非放棄iPhone3G、iPod Touch ~
而iPad程式呢～就要以256MB來思考，沒錯～iPad1的畫面比較大
，但可用就的內存就是比iPhone4來的少～～～～冏～～

真機調試 Received memory warning. Level= …

2011-08-08T06:52:00.000-07:00

OSMemoryNotification.h



typedef enum {

OSMemoryNotificationLevelAny      = -1,

OSMemoryNotificationLevelNormal   =  0,

OSMemoryNotificationLevelWarning  =  1,

OSMemoryNotificationLevelUrgent   =  2,

OSMemoryNotificationLevelCritical =  3

} OSMemoryNotificationLevel;

How the levels are triggered is not documented. SpringBoard is configured to do the following in each memory level:

1.Warning (not-normal) — Relaunch, or delay auto relaunch of nonessential background apps e.g. Mail.
2.Urgent — Quit all background apps, e.g. Safari and iPod.
3.Critical and beyond — The kernel will take over, probably killing SpringBoard or even reboot.
4.Killing the active app (jetsam) is not handled by SpringBoard, but launchd.

參考文章

在cocos2d呢
1 .Received memory warning. Level= 1
會觸發 [[CCDirector sharedDirector] purgeCachedData];



- (void)applicationDidReceiveMemoryWarning:(UIApplication *)application {

[[CCDirector sharedDirector] purgeCachedData];

}

此時會把目前沒用到的材質釋放掉~~
~
理論上ios系統會把不必要的背景程式關掉~

遇到這個情形呢~ 先查查leak吧
如果都沒有~就就就就…砍需求or改需求or改code~~~
減少在同一畫面下的內存使用量了

2 .Received memory warning. Level= 2

目前遇到的都crash 掉了~

還是乖乖查leak …

其他的還沒遇過~哈

內存管理筆記

2011-07-31T02:15:00.000-07:00

retainCount 是 objective-c 內存管理的唯一依據. release 後自動 retainCount 減 1 ，到 0 時對象的dealloc 會被觸發。

所以永遠不該呼叫對象的 dealloc 方法

1，alloc, allocWithZone,new(帶初始化)
   為對象分配內存，retainCount為“1”，並返回此實例
2，release
   retainCount 減“1”，減到“0”時調用此對象的dealloc方法
3，retain
   retainCount 加“1”
4，copy,mutableCopy
   複製一個實例，retainCount數為“1”，返回此實例。所得到的對像是與其它上下文無關的，獨立的對象(乾淨對象)。
5，autorelease
   在當前上下文的AutoreleasePool棧頂的autoreleasePool實例添加此對象，由於它的引入使Objective-C（非GC管理環境）由全手動內存管理上升到半自動化。

CCLayer CCFadeOut unrecognized selector sent to instance !!~~~~

2011-07-07T01:16:00.000-07:00

//目前使用的是 cocos2d 2.0 rc2 版
//
//在CCLayer 淡出效果時
[self runAction:[CCFadeOut actionWithDuration:0.8f]];
//會出現
[classXX setOpacity:]: unrecognized selector sent to instance 0xXXXXXXX !!

似呼有被回呼某 selector
所以必順實做 setOpacity 讓他變更



// Set the opacity of all of our children that support it

-(void) setOpacity: (GLubyte) opacity

{

for( CCNode *node in [self children] )

{

if( [node conformsToProtocol:@protocol( CCRGBAProtocol)] )

{

[(id) node setOpacity: opacity];

}

}

}

限定只有某CCLayer 觸發 touch

Cocos2d: 取得 CCSprite 寬跟高

用 NSMutableArray 記錄與取得 int ，CGPoint

2011-06-26T18:30:00.000-07:00

Objective-C 真是一個麻煩的語言

//int 記錄與取得

[myArray addObject:[NSNumber numberWithInteger:1234]];
//..
int theNumber = [[myArray objectAtIndex:0] integerValue];

//CGPoint記錄與取得
NSArray *points = [NSArray arrayWithObjects:
  [NSValue valueWithCGPoint:CGPointMake(5.5, 6.6)],
  [NSValue valueWithCGPoint:CGPointMake(7.7, 8.8)], nil];
NSValue *val = [points objectAtIndex:0];
CGPoint p = [val CGPointValue];

Error:Xcode 4 Error: Error Starting Executable!!!

2011-06-16T21:01:00.000-07:00

今天遇到一個怪問題:
XCode 4 編譯時跳出錯誤視窗

Error: Error Starting Executable!
Error launching remote program: No such file or directory. ...... 之類的，看嘸~

明明沒改到什麼東西，而且這個也不像 Code 的問題

怎麼發生的還不知到~~
最後解決方法是
1.把 Device上的程式砍掉~
2.把XCode4 關掉
3.重開機

傑克，這真是太神奇了~ 一切又可編譯了~

let the CCSprite detect touch(讓CCSprite 觸發 touch 事件)

2011-06-16T01:54:00.000-07:00

1. 首先在你的 CCLayer 開啟觸碰
self.isTouchEnabled = YES;

2. 然後一樣在 CCLayer 加入這一段

- (void)ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event{
    UITouch* touch = [touches anyObject];
    //先取得touch 的坐標
    CGPoint location = [touch locationInView:[touch view]];
location = [[CCDirector sharedDirector] convertToGL:location];
 
    //驗證坐標
CCSprite *m_targetSprite = xxx;   <==取得目標物件
    if (CGRectContainsPoint(m_targetSprite.boundingBox, location))
    {
//touch.....
}}

附註： 有時CCLayer 的坐標也要考慮進去才行~~~

warning: Semantic Issue: Local declaration of 'm_aniWelcome' hides instance variable 的意思...

warning: Semantic Issue: Local declaration of 'm_aniWelcome' hides instance variable

假設

//--------

}

嗯~就是變數重覆!!! 編譯器在抱怨了~~

cocos2d UITextField!!( 1.0.0 rc2)

2011-06-14T01:42:00.000-07:00

想要在 cocos2d的環境下，呼叫 keyboard 出來
目前版本CCLabel似乎沒有支援，在拜請google神之後，到是找到另一個方法，所以先記錄下來

原文:http://stackoverflow.com/questions/693483/textfield-example-in-cocos2d

這個解法是把UITextField 想辦法放到目前的畫面，自然就可以支援 keyboard 了~~

重點 (1) 創建一個 UITextField *myText;
(2)讓你的 layer <UITextFieldDelegate>
(3)把 myText 加到畫面上 (討厭的新舊版小細節)

[[[[CCDirector sharedDirector] openGLView] window] addSubview:myText];
    [myText becomeFirstResponder];

(4) 一些mothed

-(BOOL)ccTouchesBegan:(NSSet  *)touches withEvent:(UIEvent *)event

-(BOOL)textFieldShouldReturn:(UITextField *)textField 
-(void)textFieldDidEndEditing: (UITextField *)textField

主要code 節錄:
//------------------------------------------------------------------------------------------------------------------------------
.h

#import <UIKit/UIKit.h>
#import "cocos2d.h"
@interface MYSCENE : Layer <UITextFieldDelegate>
{
    UITextField *myText;
}
-(void)specificStartLevel;
@end
@interface textFieldTestAppDelegate : NSObject <UIAccelerometerDelegate, UIAlertViewDelegate, UITextFieldDelegate, UIApplicationDelegate>
{
    UIWindow *window;
}
@end

//------------------------------------------------------------------------------------------------------------------------------

#import "textFieldTestAppDelegate.h"
@implementation MYSCENE-(id) init{
    self = [super init];
    isTouchEnabled = YES;
    return self;
}
-(BOOL)ccTouchesBegan:(NSSet  *)touches withEvent:(UIEvent *)event {
    [self specifyStartLevel];
    return kEventHandled;
}
-(void)specifyStartLevel {
    myText = [[UITextField alloc] initWithFrame:CGRectMake(60, 165, 200, 90)];
    [myText setDelegate:self];
    [myText setText:@""];
    [myText setTextColor: [UIColor colorWithRed:255 green:255 blue:255 alpha:1.0]];
    [[[[Director sharedDirector] openGLView] window] addSubview:myText];
    [myText becomeFirstResponder];
}
-(BOOL)textFieldShouldReturn:(UITextField *)textField {
    [myText resignFirstResponder];
    return YES;
}

[cocos2d] 如何加 Accelerometer ?

2011-06-03T03:28:00.000-07:00

(1) 到想要實作的 CCLayer  ，打開
   self.isAccelerometerEnabled = YES

(2)在 init 或開始動作的地方實作
   [[UIAccelerometer sharedAccelerometer] setUpdateInterval: (1.0 / 60)];

(3)然後增加觸發的 SEL
  - (void)accelerometer:(UIAccelerometer*)accelerometer didAccelerate:(UIAcceleration*)acceleration
{
//

NSLog(@"x :%f ,y:%f ,z:%f" ,acceleration.x,acceleration.y,acceleration.z);

}

(4)最後注意，此收的到座標系跟 cocos2d 是不同的，記得要轉換一下。

ps: 開關只要設定 self.isAccelerometerEnabled 就OK了

objective-c SEL 跟 NSString 轉換!!

2011-05-29T20:31:00.000-07:00

SEL 轉 NSString
NSString *msg = [NSString stringWithFormat:@"%@ doesn't exist!",NSStringFromSelector(selector)];
常常用來記錄一些錯誤!!;
//-----------------------------------------------
NSString 轉 SEL
NSString *actionName = [NSString stringWithFormat:@"%@:",action.m_Action];
SEL actionFunc = NSSelectorFromString(actionName);
then you can do like:
[self performSelector:actionFunc];
常常用來 在runtime  動態產生 SEL
