ios - 你如何在 Cocos2D V3 的 CCScene 中检测触摸？

Question

我知道你以前可以通过:

<CCLayerObject>.isTouchEnabled = YES;

...结合触摸调度程序的注册:

-(void)registerWithTouchDispatcher
{
    [[[CCDirector sharedDirector] touchDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];
}

...然后就得到回调:

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
    CGPoint point = [self convertTouchToNodeSpace:touch];
    NSLog(@"X:%ftY:%f", point.x, point.y);
}

但是你需要在 V3 中做什么？

Answer 1

看起来我所要做的就是:

在 CCScene 构造函数中，启用触摸:

[self setUserInteractionEnabled:YES];

添加touchBegan方法:

- (void)touchBegan:(UITouch *)touch withEvent:(UIEvent *)event {
    NSLog(@"touchBegan");
}

哒哒!在 V3 中比在 V2 中容易得多!

可选地，还可以:

[self setMultipleTouchEnabled:YES];
