【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。
