【Unity3D入门教程】鼠标和键盘输入与控制

本文讲述了怎样进行鼠标和键盘的输入信息检测。外部设备输入检测需要每一帧运行，所以检测的函数需要写在Update函数中。本文讲的内容比较简单，直接上代码吧。

using UnityEngine;using System.Collections;public class InputMethod : MonoBehaviour {    int mPressMouseLeft = 0;    int mPressMouseRight = 0;    int mPressMouseMiddle = 0;void Start () {}void Update () {        //鼠标按下事件        if (Input.GetMouseButtonDown(0))        {            Debug.Log("按下了鼠标左键");        }        if (Input.GetMouseButtonDown(1))        {            Debug.Log("按下了鼠标右键");        }        if (Input.GetMouseButtonDown(2))        {            Debug.Log("按下了鼠标中键");        }        //鼠标抬起事件        if (Input.GetMouseButtonUp(0))        {            Debug.Log("抬起了鼠标左键");        }        if (Input.GetMouseButtonUp(1))        {            Debug.Log("抬起了鼠标右键");        }        if (Input.GetMouseButtonUp(2))        {            Debug.Log("抬起了鼠标中键");        }        //鼠标长按事件        if (Input.GetMouseButton(0))        {            mPressMouseLeft++;                   }        else        {            if (mPressMouseLeft > 0)            {                Debug.Log("鼠标左键按下的帧数为: " + mPressMouseLeft.ToString());            }            mPressMouseLeft = 0;        }        if (Input.GetMouseButton(1))        {            mPressMouseRight++;                  }        else        {            if (mPressMouseRight > 0)            {                Debug.Log("鼠标右键按下的帧数为: " + mPressMouseRight.ToString());             }            mPressMouseRight = 0;        }        if (Input.GetMouseButton(2))        {            mPressMouseMiddle++;         }        else        {            if (mPressMouseMiddle > 0)            {                Debug.Log("鼠标中键按下的帧数为: " + mPressMouseMiddle.ToString());            }            mPressMouseMiddle = 0;        }        //键盘按下事件        if (Input.GetKeyDown(KeyCode.Space))        {            Debug.Log("按下了空格");        }        //键盘抬起事件        if (Input.GetKeyUp(KeyCode.Space))        {            Debug.Log("抬起了空格");        }        //键盘长按事件        if (Input.GetKey(KeyCode.Space))        {            Debug.Log("空格正在被按下状态");        }}}

运行后，点击鼠标和空格键，会看到如下结果。
