动画完成后的cocos2d的autoremove的精灵 [英] cocos2d autoremove sprite after animation

问题描述

我是新来的Cocos2D和iPhone开发的。我想创造一些动画，当与它的一些物理对象的精灵被销毁（例如来显示闪现）。我想做出一些对象，我会说：运行动画并在完成后毁了你自己。然后我想这个对象忘记 - 当动画结束后应该自动销毁。什么是做到这一点的最好方法是什么？

I'm new to cocos2d and to iphone development at all. I want to create some animation, when some physical object with it's sprite is destroyed (for example to show a splash). And i want to to make some object i will say to: run the animation and destroy yourself when done. Then i want to forget about this object - it should be destroyed automatically when animation is finished. What is the best way to do it?

推荐答案

您可以使用CCSequence创建的操作列表。你做的第一个动作应该是常规动作（或序列）。第二个动作要CCCallFuncND行动，在那里你可以调用清理功能，并通过给定的精灵。

You can use CCSequence to create a list of actions. The first action you do should be your regular action (or sequence). The second action should be CCCallFuncND action, where you can call a cleanup function and pass the given sprite.

关闭我的头顶，我会做这样的事情：

Off the top of my head I'd do something like this:

CCSprite* mySpriteToCleanup = [CCSprite spriteWithFile:@"mySprite.png"];
[self addChild:mySpriteToCleanup];

// ... do stuff

// start the destroy process
id action1 = [CCIntervalAction actionWithDuration:0];  // the action it sounds like you have written above.
id cleanupAction = [CCCallFuncND actionWithTarget:self selector:@selector(cleanupSprite:) data:mySpriteToCleanup];
id seq = [CCSequence actions:action1, cleanupAction, nil];
[mySpriteToCleanup runAction:seq];

和清理功能：

- (void) cleanupSprite:(CCSprite*)inSprite
{
    // call your destroy particles here
    // remove the sprite
    [self removeChild:inSprite cleanup:YES];
}

您可以在这两个动作之间的另一个操作添加，以及为您的摧毁行动的粒子而不是调用，在年底的功能。

You could add in another action between these two actions as well for your destroy particle actions instead of calling that in the end function.
