Question

如何检查播放器是否每帧都在触摸屏幕？我想要一些类似的东西，当你在游戏中触摸屏幕几何短跑，如果你触地，你继续跳跃。我尝试了这个，但我没有工作：

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    isTouching = true
}

与touchDown函数相同：

func touchDown(atPoint pos : CGPoint) {
        isTouching = true
    }

Answer 1

请尝试以下代码：

var isTouching = false

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    isTouching = true
}

override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
    isTouching = false
}

Answer 2

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    isTouching = true
}

override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
    isTouching = false
}

然后您可以检查更新循环

if isTouching == true { 
   do something 
}
else {
   do something else 
}

如果玩家正在触摸屏幕，如何检查每个帧？
