使用Cocos 2d和Box 2d渲染紋理

Question

我有一個Cocos2d和Box2D應用程序。我有一個圖像bubble.png。我想在用戶滑動屏幕時畫出一連串的氣泡。

誰能告訴我如何做到這一點？

感謝

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我想註冊...（[層registerWithTouchDispatcher]）

[glView setMultipleTouchEnabled：YES]; （也許這是需要刷卡）
