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;
}
else
{
if (touchXEnd > touchXBegin)
{
if (touchYEnd > touchYBegin)
{
if (touchXEnd - touchXBegin > slipNum && ((touchXEnd - touchXBegin) > (touchYEnd - touchYBegin)))
{
//slide up
TouchPadKey.slideup = true;
}
if (touchYEnd - touchYBegin > slipNum && ((touchYEnd - touchYBegin) > (touchXEnd - touchXBegin)))

//slide right
TouchPadKey.slideright = true;

方法使用示例
void Update()
{
Debug.Log("x:"+TouchPadPosition.x);
Debug.Log("y:"+TouchPadPosition.y);
ShowText_x.text = "x:" + TouchPadPosition.x.ToString();
ShowText_y.text = "y:" + TouchPadPosition.y.ToString();
if ( TouchPadKey.slideup )
{
Debug.Log("向上滑");
}
if ( TouchPadKey.slidedown )

}
if ( TouchPadKey.slideleft )
{
Debug.Log("向左滑");
}
if ( TouchPadKey.slideright )

Debug.Log("向右滑");
}
if ( TouchPadPosition.x != 0 || TouchPadPosition.y != 0 )
{
//to do something
}
}
更多的功能可以摸索实现。
