CCJumpBy在sprite上 [英] CCJumpBy on a sprite

问题描述

这是我的第一个Cocos2D项目，我试图使一个sprite在触摸时在同一个地方跳跃，但我不能让它响应，因为我不知道如何设置触摸sprite上的动作。
下面是代码：

   - （void）spriteEffect 
 {
 CCSprite * actionEffect = avatar; 
 id jump = [CCJumpBy actionWithDuration：1 position：ccp（0，0）height：50 jumps：2]; 
 id sequence = [CCSequence actions：jump，nil]; 
 [actionEffect runAction：sequence]; 
 
 return yes 
} 
  

p>

   - （BOOL）ccTouchBegan：（UITouch *）touch withEvent：（UIEvent *）event 
 
解决方案
谢谢！
 code> avatar 是一个sprite数组，帮助澄清为什么你看不到任何效果。尝试做如下操作：
   - （void）spriteEffect 
 {
 CCSprite * actionEffect =<从头像数组获取精灵> ;; 
 id jump = [CCJumpBy actionWithDuration：1 position：ccp（0，0）height：50 jumps：2]; 
 [actionEffect runAction：jump]; 
  
} 
 
 
 
我不知道什么样的数组 avatar 是，所以我不能提供访问它的元素的语法。如果 avatar 是 NSArray ，您可以使用以下命令跳转所有sprite：
   - （void）spriteEffect 
 {
 foreach（CCSprite * actionEffect in avatar）{
 id jump = [CCJumpBy actionWithDuration ：1 position：ccp（0，0）height：50 jumps：2]; 
 [actionEffect runAction：jump]; 
} 
  
} 
 
These are my first Cocos2D projects, I'm trying to make a sprite jump in the same place when touched, but I can't make it response because I don't know how to set touch actions on sprites.
Here is the code :
-(void) spriteEffect
{
    CCSprite *actionEffect = avatar;
    id jump = [CCJumpBy actionWithDuration:1 position: ccp(0, 0) height:50 jumps:2];
    id sequence = [CCSequence actions: jump, nil];
    [actionEffect runAction:sequence];

    return yes
}
Should I use a 
- (BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
Thanks!
解决方案
Your comment that avatar is an array of sprites helps clarifying why you don't see any effects. Try to do something like:
-(void) spriteEffect
{
 CCSprite *actionEffect = <get a sprite from avatar array>;
 id jump = [CCJumpBy actionWithDuration:1 position: ccp(0, 0) height:50 jumps:2];
 [actionEffect runAction:jump];
}

I don't know what kind of array avatar is, so I can't provide syntax for accessing its elements. If avatar is an NSArray, you can make all of your sprites jump by using:
-(void) spriteEffect
{
   foreach (CCSprite* actionEffect in avatar) {
     id jump = [CCJumpBy actionWithDuration:1 position: ccp(0, 0) height:50 jumps:2];
     [actionEffect runAction:jump];
   }
}
