touchesBegin in specific area (Swift)

Question

我想用 覆盖 func touchesbegan 是 spritekit。 但是火箭只会在触摸屏幕的特定部分（例如图像）时才会生成，而不是整个屏幕。

Answer 1

  override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    let area = CGRect(x: 0, y: 0, width: 100, height: 100)
    guard let point = touches.first?.location(in: view),
          area.contains(point) else {
      return
    }
    //Spawn Logic Here
  }
