CCMoveTo不工作，节点/场景问题？ [英] CCMoveTo not working, node/scene issue?

问题描述

我有一个名为SuccessLayer的CCLayer类。当级别完成时，它被添加到场景，如下：

  SuccessLayer * successLayer = [SuccessLayer node]; 
 [self addChild：successLayer]; 
  

在SuccessLayer中，我想要一个摇滚，我试图实现：

   - （void）onEnter {
 Asteroid * asteroid = [Asteroid spriteWithFile：@rocks.png] ; 
 asteroid.position = ccp（0，500）; 
 [self addChild：asteroid]; 
 CCMoveTo * move = [CCMoveTo actionWithDuration：2.0 position：ccp（1000，0）]; 
 [asteroid runAction：move];} 
  

> CCMoveTo 无法正常工作。我看到sprite坐在它的初始坐标，但没有更多。我在这里缺少什么？感谢

解决方案

通过将其转换为CCSprite来解决问题（是正确的说法吗？）

  CCSprite * asteroid = [Asteroid spriteWithFile：@rocks.png]; Asteroid 已经是CCSprite的子类，因此，所以我不知道为什么这个工作，但它允许我现在就对它运行的行动。
 
I have a CCLayer class called SuccessLayer. It gets added to the scene when the level is complete, like so:
SuccessLayer *successLayer = [SuccessLayer node];
[self addChild:successLayer];
In SuccessLayer, I want to have a rock fly by, I'm trying to achieve that with this:
-(void)onEnter{
    Asteroid *asteroid = [Asteroid spriteWithFile:@"rocks.png"];
    asteroid.position = ccp(0, 500);
    [self addChild:asteroid];
    CCMoveTo *move = [CCMoveTo actionWithDuration:2.0 position:ccp(1000, 0)];
    [asteroid runAction:move];}
However, it seems CCMoveTo isn't working. I see the sprite sitting at its initial coordinates, but nothing more. What am I missing here? Thanks
解决方案
Sovled the problem by casting it as a CCSprite (is that the correct way to say it?)
CCSprite *asteroid = [Asteroid spriteWithFile:@"rocks.png"];
Asteroid is already a subclass of CCSprite, so I have no idea why this works, but it allows me to run actions on it now.
