精靈三秒消失 cocos2d

1.問題描述：如果我想讓一個 sprite 顯示3秒鍾然後消失，

使用 CCDelayTime 和 CCCallFunc

Oc代碼

CCSprite *sprite = [CCSprite spriteWithFile:@"blabla.png"];
[layer addChild:sprite];
CCDelayTime* waitAction = [CCDelayTime actionWithDuration:3]; //等待3秒
CCCallFunc* vanishAction = [CCCallFunc actionWithTarget:self selector:@selector(removeSprite:)]; //調用removeSprite:方法
CCSequence* sequence = [CCSequence actions:waitAction, vanishAction, nil];
[sprite runAction:sequence];
// 在 removeSprite: 裏
[sprite removeFromParentAndCleanup:YES];

2.0.9.6以後的動作

由於0.9.9.5以後沒有spritesheet 了，但是之前的教程卻都用這個方法，找了老半天，終於知道新版本的動畫效果製作了：

Oc代碼

CCSpriteBatchNode * spritesheet = [CCSpriteBatchNode batchNodeWithFile:@"bee.png"];
[self addChild:spritesheet];
for (int i = 0; i < 2; i++) {
CCSpriteFrame* frame = [[CCSpriteFrame alloc] initWithTexture:spritesheet.texture rect:CGRectMake(i*38, 0, 37, 38)];
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFrame:frame name:[NSString stringWithFormat:@"playerFrame%d", i]];
[frame release];
}
SPBee = [[CCSprite alloc] initWithSpriteFrameName:[NSString stringWithFormat:@"playerFrame%d", 0]];
[spritesheet addChild:SPBee];
[SPBee release];
[SPBee setPosition:CGPointMake(260, winSize.height-305)];
NSMutableArray* animFrames = [NSMutableArray array];
for (int i = 0; i < 2; i++) {
CCSpriteFrame* frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"playerFrame%d", i]];
[animFrames addObject:frame];
}
CCAnimation *animation = [CCAnimation animationWithFrames:animFrames delay:0.2f];
[SPBee runAction:[CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:animation restoreOriginalFrame:NO]]];
