Unity Pico手柄触摸圆盘滑动功能

Pico 开发SDK 中实现了对手柄触摸圆盘中上滑，下滑，左滑，右滑的判定，只是将这些方法写进了拓展的API中，并且默认是不被启用的。所以我们通过查看源码便可轻松调用里面的方法属性。
查看SDK中Pvr_ControllerManager.cs中第304行开始。

我们发现在拓展的API中实现了长按和滑动的功能，通过ExtendedAPI控制是否启用。我们可以将ExtendedAPI设置为True,调用里面的布尔属性：

  TouchPadKey.slideright   //向右滑动
    TouchPadKey.slideleft //向左滑动
    TouchPadKey.slidedown //向下滑动
    TouchPadKey.slideup //向上滑动

 #region extended api
            //打开扩展API后，提供长按和滑动功能
            if (ExtendedAPI)
            {
                //slip
                if (TouchPadPosition.x > 0 || TouchPadPosition.y > 0)
                {
                    if (!touchClock)
                    {
                        touchXBegin = TouchPadPosition.x;
                        touchYBegin = TouchPadPosition.y;
                        touchClock = true;
                    }
                    touchXEnd = TouchPadPosition.x;
                    touchYEnd = TouchPadPosition.y;
                }
