cocos2D中的应用动画延迟

Question

代码：

if (CGRectIntersectsRect(food.sprite.boundingBox, playerRect)) {
    [food.sprite stopAllActions]; 

    [walkAnimFrames addObject: [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:

    [NSString stringWithFormat:@"newpackman2.png", 0]]];

    [walkAnimFrames addObject: [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:

    [NSString stringWithFormat:@"newpackman3.png", 1]]];

    walkAnim = [CCAnimation animationWithFrames:walkAnimFrames delay:0.2f];

    self.walkAction = [CCRepeatForever actionWithAction: [CCAnimate actionWithAnimation:walkAnim restoreOriginalFrame:NO]];

    self.walkAction.tag = 1;
    [chef runAction:_walkAction];
}

这段代码可以正常运行，在固定时间会触发动画。

但是我需要动画在3-4秒的延迟之后开始。

我用过 [sprite stopActionByTag:1] 没有实现。请高手帮忙，谢谢

你可以创建一个动作block来实现延迟，调用stopAllActions:

CCSprite *sprite = ...;

CCCallBlock *block = [CCCallBlock actionWithBlock:^{
            [sprite stopAllActions];
        }];

然后使用CCDelayTime:

CCDelayTime *time = [CCDelayTime actionWithDuration:4];


[sprite runAction:[CCSequence actions:time, block, nil]];
