所以我一直在为Unity中的游戏编写一些代码，而我正在使用Input.GetMouseButtonDown（1）函数。但是，它仅在我第一次在游戏中按鼠标左键时有效，此后没有其他时间。播放器控制器的使用代码如下：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class PlayerController : MonoBehaviour {
public float speed;
public Transform enemy;
public Transform shot;
public GameObject shotObj;
public Text scoreT;
public Text timeT;
public Text roundT;
public float health;
public float damageTaken;
public Vector3 lookPoint;
public float shotSpeed;
private Camera mainCamera;
private int round = 1;
private int tempRound = 0;
private float time = 300;
private bool win = false;
private bool allowShoot;
private EnemyController enemyScript;
private ShotController shotScript;
private bool tempImune = false;
private int targetTime;
private int score = 0;
private int defeatedEnemy = 0;
private GameObject enemyObj;
//coroutine
IEnumerator Pause(float timE)
{
allowShoot = false;
//time since the object was created
float start = Time.realtimeSinceStartup;
//sets the game to slow down to 0 movement
Time.timeScale = 0.0f;
//loops until start up time is less than start time + pause time
while (Time.realtimeSinceStartup < start + timE)
{
//returns null from the subroutine and restarts the subroutine at this point after null (0) time has passed
yield return null;
}
//sets the gamne to be running at normal speed
Time.timeScale = 1.0f;
allowShoot = true;
if (timE == 5.0f)
{
roundT.gameObject.SetActive(false);
}
}
void Start () {
//center mouse
Cursor.lockState = CursorLockMode.Locked;
Cursor.lockState = CursorLockMode.None;
//set camera to be the camera in the scene (should only ever be one camera in the scene)
mainCamera = FindObjectOfType<Camera>();
//set default text values
scoreT.text = "Score: 000000";
timeT.text = "Time Left: 600";
roundT.text = "Round: " + round;
//pause game before first round begins
StartCoroutine(Pause(5.0f));
}
void Update () {
//looka at mouse script
Ray cameraRay = mainCamera.ScreenPointToRay(Input.mousePosition);
Plane ground = new Plane(Vector3.up, Vector3.zero);
float rayLength;
if (ground.Raycast(cameraRay, out rayLength))
{
lookPoint = cameraRay.GetPoint(rayLength);
transform.LookAt(new Vector3(lookPoint.x, transform.position.y, lookPoint.z));
}
//enemy spawner check and win criteria check
if (defeatedEnemy != 45)
{
if (round != tempRound)
{
spawnEnemy();
roundT.gameObject.SetActive(true);
if (round == 5)
{
roundT.text = "Round: " + round + "(Final Round)";
}
else
{
roundT.text = "Round: " + round;
}
StartCoroutine(Pause(5.0f));
}
}
else
{
win = true;
}
//timer and win check
if (health == 0f)
{
win = true;
}
if (!win)
{
time -= Time.deltaTime;
timeT.text = "Time Left: " + time;
}
else
{
if (health == 0f)
{
roundT.gameObject.SetActive(true);
int finalScore = Mathf.RoundToInt(score * ((time / 2) / 10));
roundT.text = "To Bad, You Loose! Score = " + finalScore;
Debug.Log(finalScore);
StartCoroutine(Pause(99999f));
}
else
{
roundT.gameObject.SetActive(true);
int finalScore = Mathf.RoundToInt(score * ((time / 2) / 10));

}
}
//movement controlls
if (Input.GetKey(KeyCode.W) || Input.GetKey(KeyCode.UpArrow))

}

}
}
}
void spawnEnemy()
{

}
}
void OnCollisionEnter(Collision col)
{
if (col.gameObject.tag == "Enemy")
{
if (!tempImune)
{
health = health - damageTaken;
Debug.Log(health);
tempImune = true;
targetTime = Mathf.RoundToInt(time) - 1;
}
}
}
}
对此的任何帮助将不胜感激，因为它是用于学校项目的。谢谢。

由于状态每帧都会重置，因此您需要从Update函数调用此函数。除非用户释放鼠标按钮并再次按下它，否则它不会返回true。主按钮（通常是左按钮）的值为0，辅助按钮为1，中间按钮为2
using UnityEngine;
using System.Collections;
public class ClassName : MonoBehaviour
{
void Update()
{
if (Input.GetMouseButtonDown(0))
Debug.Log("Pressed primary button.");
if (Input.GetMouseButtonDown(1))
Debug.Log("Pressed secondary button.");
if (Input.GetMouseButtonDown(2))
Debug.Log("Pressed middle click.");
}
}
