cocos2d中重复背景有黑边！
我正在尝试为我的 iPhone 应用程序设置平铺/重复背景。
代码“有效”，因为背景按应有的方式重复，但每次重复周围似乎都有黑色边框，我不知道为什么，图像恰好是 200x200。下面是它的外观和代码的屏幕截图：
if ((self=[super init])) {
CCSprite * bg = [CCSprite spriteWithFile:@"pattern11.jpg" rect:CGRectMake(0, 0, 1000, 520)];
[bg setPosition:ccp(0, 0)];
ccTexParams params = {GL_LINEAR,GL_LINEAR,GL_REPEAT,GL_REPEAT};
[bg.texture setTexParameters:¶ms];
[self addChild:bg z:0];
}
I am attempting to setup a tiled/repeating background for my iPhone app.
The code "works" in that the background is repeating like it should be but I seem to have a black border around each repetition and I dont know why, the image is exactly 200x200. Here is a screenshot of how it looks along with the code:
if ((self=[super init])) {
CCSprite * bg = [CCSprite spriteWithFile:@"pattern11.jpg" rect:CGRectMake(0, 0, 1000, 520)];
[bg setPosition:ccp(0, 0)];
ccTexParams params = {GL_LINEAR,GL_LINEAR,GL_REPEAT,GL_REPEAT};
[bg.texture setTexParameters:¶ms];
[self addChild:bg z:0];
}

纹理应该始终是 2 的幂...例如 16,32,64,128,256,512,1024。
尝试将图像大小调整为 256x256 或 128x128。
Textures should always be in power of two... like 16,32,64,128,256,512,1024.
Try resizing the image to 256x256 or 128x128.
我还遇到过这个相当常见的问题，即无法在 Cocos2d-iPhone 中平铺任意大小的纹理，因此我组合了一个简单的 TiledSprite 类来平铺/剪辑纹理或子纹理到任何宽度/高度。

祝你好运！
I've also ran across this rather common problem with not being able to tile arbitrarily-sized textures in Cocos2d-iPhone, so I put together a simple TiledSprite class to tile/clip a texture or subtexture to any width/height.
Jump right to the source code here (use at will):

Or have a look at a usage sample, screenshot, and commentary in this brief article:

Best of luck!
