sprite sheet不工作的视网膜显示 [英] sprite sheet not working for retina display

问题描述

我为非视网膜显示创建了 sprite sheet ，并在模拟器上工作罚款
我使用了代码

   - （Void）addSprites {
 [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile：@image .plist]; 
 
 CCSpriteBatchNode * spriteSheet = [CCSpriteBatchNode batchNodeWithFile：@image.png]; 
 [self addChild：spriteSheet]; 
 
 //加载我们动画的帧
 NSMutableArray * walkAnimFrames = [NSMutableArray array]; 
 for（int i = 1; i <5; i ++）{
 [walkAnimFrames addObject：[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName：[NSString stringWithFormat：@image％d.png，i] ]; 
} 
 
 CCAnimation * walkAnim = [CCAnimation animationWithSpriteFrames：walkAnimFrames delay：0.20f]; 
 //为我们的熊创建一个sprite 
 
 background = [CCSprite spriteWithSpriteFrameName：@image1.png]; 
 background.position = ccp（280，175）; 
 self.walkAction = [CCRepeatForever actionWithAction：[CCAnimate actionWithAnimation：walkAnim]]; 
 [spriteSheet addChild：background]; 
} 
  - （void）startAnimation {
 [background runAction：_walkAction]; 
  

}

创建了具有双倍大小的视网膜图像的sprite图像，命名为 image @ 2x .. 的图像。创建的 plist code> myplist @ 2xplist 和图片文件 [e-mail]

我的意思是有4个文件

用于非视网膜显示。

1） imagefile.png（sprite sheet）

2） myPlist.plist





c $ c> [e-mail]（sprite sheet）
每个图像的plist键名也像[e-mail]

2） [e-mail]

，但上述代码不适用于此代码。我做错了或丢失的东西？
我的应用在设备上崩溃，显示错误消息

  CCSpriteFrameCache：未找到框架'image1.png'
 2013-05-03 16：19：49.764 ***由于未捕获异常而终止应用程序
'NSInvalidArgumentException'，原因：'***  -  [__ NSArrayM insertObject：atIndex：]：object不能为nil'
  

但上述代码是在模拟器上正常工作 p>

解决方案

默认情况下cocos2d使用-hd后缀而不是@ 2x。并且sprite表内的文件名需要是相同的，没有任何-hd或@ 2x。只有主sprite表文件名需要使用后缀-hd。

myPlist-hd.plist

I have create a sprite sheet for non retina display and its working fine on simulator.. I have used the code

 -(Void)addSprites{
     [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"image.plist"];

    CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"image.png"];
    [self addChild:spriteSheet];

 // Load up the frames of our animation
    NSMutableArray *walkAnimFrames = [NSMutableArray array];
    for(int i = 1; i < 5; i++) {
        [walkAnimFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"image%d.png", i]]];
    }

    CCAnimation *walkAnim = [CCAnimation animationWithSpriteFrames:walkAnimFrames delay:0.20f];
// Create a sprite for our bear

    background = [CCSprite spriteWithSpriteFrameName:@"image1.png"];
    background.position = ccp(280, 175);
    self.walkAction = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:walkAnim]];
    [spriteSheet addChild:background];  
}
 -(void)startAnimation{
    [background runAction:_walkAction];

}

And for for device i have created sprite sheet with retina image with double size and image named like image@2x.. the created plist is myplist@2xplist and image file is [e-mail]

I mean there are 4 files

for non retina display.

1) imagefile.png(sprite sheet)

2) myPlist.plist

for Retina display.

1) [e-mail](sprite sheet) the plist key name for every image is also like [e-mail]

2) [e-mail]

but the above code is not working for this code. m i doing something wrong or missing somthing? my app crash on device with error message

 CCSpriteFrameCache: Frame 'image1.png' not found
2013-05-03 16:19:49.764  *** Terminating app due to uncaught exception 
'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object    cannot be nil'

but the above code is working fine on simulator

解决方案

By default cocos2d use -hd postfix not "@2x". And file names inside the sprite sheet need to be same without any "-hd" or @2x. Just the main sprite sheet file name need to be with postfix "-hd".

myPlist-hd.plist
