Cocos2d: 取得 CCSprite 寬跟高

 //取得 CCSprite 寬跟高

CCSprite *sp = [CCSprite spriteWithFile:@"Icon.png"];

NSLog(@"sp width:%f,heigt,:%f",sp.contentSize.width , sp.contentSize.height);

用 NSMutableArray 記錄與取得 int ，CGPoint

Objective-C 真是一個麻煩的語言

//int 記錄與取得

myArray = [NSMutableArray array];
[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];

load url image

// 用UIView的

id path = @"https://www.google.com/images/logos/ps_logo2.png";
NSURL *url = [NSURL URLWithString:path];
NSData *data = [NSData dataWithContentsOfURL:url];
// UIImage *img = [[UIImage alloc] initWithData:data cache:NO];
UIImage *img =[ UIImage imageWithData:data];

UIImageView *imView = [[UIImageView alloc] initWithImage:img];

[self.view addSubview:imView ];


//在cocos2d

id path = @"https://www.google.com/images/logos/ps_logo2.png";
NSURL *imgUrl = [NSURL URLWithString:path];
UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:imgUrl]];
CCTexture2D *tt2d = [[CCTexture2D alloc] initWithImage:image];
CCSprite *sp = [CCSprite spriteWithTexture:tt2d];
[self addChild: sp];


cocos2d:開啟muti touch

在 AppDelegate.m

- (void) applicationDidFinishLaunching:(UIApplication*)application

  //開啟muti touch

    [glView setMultipleTouchEnabled:YES];   // <===新增這一行

}

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

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)

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

//--------

the.h

@interface myLayer : CCLayer {

    AAA *a;

}

//--------

the.m

-(id)init{

    self = [super init];

    if (self) {

      AAA *a = [[AAA alloc] init];   <====這一行會有 !

    }

   return self;

}

嗯~就是變數重覆!!!  編譯器在抱怨了~~

cocos2d UITextField!!( 1.0.0 rc2)

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:
