标题: Unity3D控制鼠标隐藏

今天学习的是控制鼠标指针的隐藏，相信大家都在看视频时发现，如果选择了全屏播放模式，过一会儿如果不移动鼠标的话，鼠标指针就会慢慢隐藏，便于大家欣赏大片。

今天就带来一个脚本来实现这个功能。只要在场景中将如下脚本拖入任意游戏对象，运行场景，就可以看到效果了。

脚本如下：
using UnityEngine;
using System.Collections;

public class PointerManager : MonoBehaviour
{
//定义一个鼠标状态的枚举
public  enum PointerState
{
      stateInvisible,
      stateVisible,
      stateSetInvisible,
      stateSetVisible
}

public PointerState pointerState = PointerState.stateSetInvisible;
public float timeOutReset = 2f;

private bool hideOverride = false;
private float timeOutCounter;
private Vector3 currentMousePosition;

void Start()
{
      //获得当前鼠标位置，以便判断是否移动了鼠标
      currentMousePosition = Input.mousePosition;
}

void Update()
{
      switch (pointerState)
      {
         case PointerState.stateInvisible:
            if (!hideOverride)
                  //移动了鼠标，保持指针可见状态
                  if (Input.mousePosition != currentMousePosition)
                     pointerState = PointerState.stateSetVisible;
            break;
         case PointerState.stateVisible:
            //开始计时，如果鼠标长时间不动，则隐藏鼠标指针
            if (timeOutCounter > 0f)
            {
                  timeOutCounter -= Time.deltaTime;
                  Debug.Log(timeOutCounter);
            }
            else pointerState = PointerState.stateSetInvisible;
            break;
         case PointerState.stateSetInvisible:
            //隐藏鼠标指针
            Screen.showCursor = false;
            currentMousePosition = Input.mousePosition;
            //转换状态
            pointerState = PointerState.stateInvisible;
            break;
         case PointerState.stateSetVisible:
            //指针可见时，重新计时
            timeOutCounter = timeOutReset;
            Screen.showCursor = true;
            pointerState = PointerState.stateVisible;
            break;

      }
}
}
