Cocos2d在一个路径上移动动画 [英] Cocos2d move animation on a path

问题描述

是否有可能在Cocos2d中创建一个移动动画，它会在一个特定的路径？

例如，如果我需要一个对象移动

解决方案

当然您可以使用：

  ccBezierConfig bezier; 
 bezier.controlPoint_1 = ccp（320,0）; //控制点1 
 bezier.controlPoint_2 = ccp（0,0）; //控制点2 
 bezier.endPosition = ccp（endPoint.x，endPoint.y）; 
 id bezierForward = [CCBezierTo actionWithDuration：3 bezier：bezier]; 
 [ball runAction：bezierForward]; 
  

您可以使用ccBezier移动曲线中的任何节点：

现在动画部分：

  [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile：@eggAnimation.plist]; 
 spriteSheet = [CCSpriteBatchNode batchNodeWithFile：@eggAnimation.png]; 
 [gameBackgroundLayer addChild：spriteSheet]; 
 eggAnimFrames = [NSMutableArray array]; 
 for（int i = 1; i <= 10; i ++）
 {
 [eggAnimFrames addObject：[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName：[NSString stringWithFormat：@％d.png ， 一世]]]; 
} 
 rotateAnim = [CCAnimation animationWithFrames：eggAnimFrames delay：0.05f]; 
 ball = [CCSprite spriteWithSpriteFrameName：@1.png]; 
 ball.position = ccp（160,80）; 
 rotateAction = [CCRepeatForever actionWithAction：[CCAnimate actionWithAnimation：rotateAnim restoreOriginalFrame：YES]]; 
 [spriteSheet addChild：ball];

Is it possible in Cocos2d to create a move animation that would go on a specific path?

For example, how should I do if I need an object to move on an arc or full circle?

Regards!

解决方案

Sure you can do this using :

    ccBezierConfig bezier;
    bezier.controlPoint_1 = ccp(320,0); // control point 1 
    bezier.controlPoint_2 =ccp(0,0); // control point 2
    bezier.endPosition = ccp(endPoint.x,endPoint.y) ;
    id bezierForward = [CCBezierTo actionWithDuration:3 bezier:bezier];
    [ball runAction:bezierForward];

you can use ccBezier to move any node in curves :

Now Animation Part :

    [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"eggAnimation.plist"];        
    spriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"eggAnimation.png"];
    [gameBackgroundLayer addChild:spriteSheet];
    eggAnimFrames = [NSMutableArray array];
    for ( int i = 1; i <= 10; i++ )  
    {
        [eggAnimFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"%d.png", i]]];
    }
    rotateAnim = [CCAnimation animationWithFrames:eggAnimFrames delay:0.05f];
    ball = [CCSprite spriteWithSpriteFrameName:@"1.png"];
    ball.position=ccp(160,80);
    rotateAction =[CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:rotateAnim restoreOriginalFrame:YES]];
    [spriteSheet addChild:ball];
