如何在 Cocos2d 3.2 中找到多个触摸的位置？

Question

我想在 CGPoint 中获取两根手指的位置。

我如何从 CCTouchEvent 中获取它？

到目前为止我已经尝试过：

-(void)touchMoved:(CCTouch *)touch withEvent:(CCTouchEvent *)event{

    if ([[event allTouches] count]==2) {

       NSLog(@"Detected");
       NSLog(@"event: %@",event.allTouches);

    }

}

Answer 1

你需要试试这个：第一个参数不再是 CCTouch 它需要是一个集合所以

-(void)ccTouchesBegan:(NSSet *)touches withEvent:(CCTouchEvent *)event{
    for(CCTouch* touch in touches){
        [touch getLocation];
    }
}

Answer 2

通过枚举 allTouches 的值：

-(void)touchMoved:(CCTouch *)touch withEvent:(CCTouchEvent *)event{

if ([[event allTouches] count]==2) {


    CGPoint fingerOne = [event.allTouches.allValues[0] locationInWorld];
    CGPoint fingerTwo = [event.allTouches.allValues[1] locationInWorld];

    NSLog(@"fingerOne: x = %f, y = %f",fingerOne.x,fingerOne.y);
    NSLog(@"fingerTwo: x = %f, y = %f",fingerTwo.x,fingerTwo.y);


 }

}
