使用Cocos 2d和Box 2d渲染纹理

Question

我有一个Cocos2d和Box2D应用程序。我有一个图像bubble.png。我想在用户滑动屏幕时画出一连串的气泡。

谁能告诉我如何做到这一点？

Answer 1

- (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ 
{ 
     //Add a new body/atlas sprite at the touched location 
     for(UITouch *touch in touches) { 

      CGPoint location = [touch locationInView: [touch view]]; 
      location = [[CCDirector sharedDirector] convertToGL: location]; 

      b2Vec2 locationWorld = b2Vec2(location.x/PTM_RATIO, location.y/PTM_RATIO); 

      CCSprite *mist=[CCSprite spriteWithFile:@"bubble.png"]; 
      mist.position=ccp(location.x,location.y); 

      [self addChild:mist]; 
     } 
}

您需要用touchdispatcher我想注册...（[层registerWithTouchDispatcher]）

[glView setMultipleTouchEnabled：YES]; （也许这是需要刷卡）
