从Texture2D迁移到CCTexture2D的问题(设置CCSprite纹理)

Question

我的问题是每当我更改精灵的纹理时,新纹理将保留原始精灵纹理的大小.

我有这个代码:

mySprite = [CCSprite spriteWithFile:@"mySprite.png"]];

...

// change current stage here 

CCTexture2D *newTexture=[[[CCTexture2D alloc]initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"stage number %d.png",currentStageNumber]]]autorelease];

[mySprite setTexture:newTexture];

新的精灵被拉伸或压缩,具体取决于原始精灵的大小.如果原始精灵较大,则会拉伸新纹理.

当我使用cocos2d v0.8时,我没有遇到这个问题

我究竟做错了什么？

解决了:

mySprite = [CCSprite spriteWithFile:@"mySprite.png"]];

...

// change current stage here

CCTexture2D *newTexture=[[[CCTexture2D alloc]initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"stage number %d.png",currentStageNumber]]]autorelease];

[mySprite setTexture:newTexture];

[mySprite setTextureRect:CGRectMake(0,0, newTexture.contentSize.width, newTexture.contentSize.height)];
