我在 cocos2d 中为 iPhone 创建了两个边界框，当它们与来自 selSprite 的图像相交时，如果它们的标签匹配，则替换 targetSprite 中的图像。当边界框碰撞时，我想给出一个漂亮的动画。以下代码成功替换了精灵，但 FadeOut 动画在图像替换后运行。当图像被替换时，动画应该运行。我究竟做错了什么？任何帮助，将不胜感激。谢谢！

if (CGRectIntersectsRect(getSpriteRect, selSpriteRect)) {

        if ([selSprite tag] == ([targetSprite tag]-7)) {
            //NSLog(@"%d", [targetSprite tag]);
            //NSLog(@"%@", [selectedSpritesToBeUsedLater objectAtIndex:[selSprite tag]]);

            CCSprite *replacedImage = (CCSprite *)[self getChildByTag:[targetSprite tag]];

            CCSprite *spriteToBeUsedInTex = [selectedSpritesToBeUsedLater objectAtIndex:[selSprite tag]];

            id removeSpriteAction = [CCFadeOut actionWithDuration:2.0f];

            id removeSelSprite = [CCCallFunc actionWithTarget:self selector:@selector(removeSelSpriteByTag)];

            CCSequence *sequence = [CCSequence actions:removeSpriteAction, removeSelSprite, nil];

            [selSprite runAction:sequence]; 

            CCTexture2D *tex = [[CCTextureCache sharedTextureCache] addImage:[NSString stringWithFormat:@"color-0%d.png", [spriteToBeUsedInTex tag]+1]];

            [replacedImage setTexture:tex];

        }
    }
} }

-(void)removeSelSpriteByTag {
[self removeChildByTag:[selSprite tag] cleanup:YES]; }

你应该使用CCSpawn而不是CCSequencethen。
