iphone-cocos2D中的應用動畫延遲

cocos2D中的應用動畫延遲

代碼：

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];
}

這段代碼可以正常運行，在固定時間會觸發動畫。

但是我需要動畫在3-4秒的延遲之後開始。

我用過 [sprite stopActionByTag:1] 沒有實現。請高手幫忙，謝謝

最佳回答：

你可以創建一個動作block來實現延遲，調用stopAllActions:

CCSprite *sprite = ...;

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

然後使用CCDelayTime:

CCDelayTime *time = [CCDelayTime actionWithDuration:4];


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