Question

我有一个简单的便签，可以让玩家单击“ Disparo”按钮（在本例中为左键）时射击预制件。现在它坏了，因为您可以向点击发送垃圾邮件并每秒射击一次。我不知道如何为此添加冷却时间，以使您只能在每个特定的时间拍摄。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;

public class ProjectileShooter : MonoBehaviour
{
public AudioClip disparo;
GameObject prefab;
public float shootSpeed;
// Start is called before the first frame update
void Start()
{
    prefab = Resources.Load("Projectile") as GameObject;
}

// Update is called once per frame
void Update()
{
    if (CrossPlatformInputManager.GetButtonDown("Disparo"))
    {
        GameObject Projectile = Instantiate(prefab) as GameObject;
        Projectile.transform.position = transform.position + Camera.main.transform.forward * 2;
        Rigidbody rb = Projectile.GetComponent<Rigidbody>();
        rb.velocity = Camera.main.transform.forward * shootSpeed;
        Destroy(Projectile, 2.2f);


    }
}

}

一种实现所需目标的方法是设置一个布尔值，以检查进程是否处于冷却状态。

private bool isInCooldown = false;

然后，在您的if语句中，您可以在完成计算后调用新方法。如Unity docs调用方法中所述：

以秒为单位调用方法methodName。

if (CrossPlatformInputManager.GetButtonDown("Disparo"))
{
    if(!isInCooldown){
       //Your code here

       Invoke("ResetCooldown", 2f);
       isInCooldown = true;
    }
}

ResetCooldown方法很简单：

private void ResetCooldown () {
    isInCooldown = false;
}

希望这会有所帮助。

以下脚本可轻松设置冷却时间。您可以通过更改 shootcoolTime 来设置冷却时间。并且不要触摸 youCanShootNow 。该变量仅在您可以再次拍摄时用于节省时间；

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;

public class ProjectileShooter : MonoBehaviour
{
    public AudioClip disparo;
    GameObject prefab;
    public float shootSpeed;
    public float shootcoolTime;

    float youCanShootNow;


    // Start is called before the first frame update
    void Start()
    {
        prefab = Resources.Load("Projectile") as GameObject;
        youCanShootNow = 0;
    }


    public void Update()
    {
        if (youCanShootNow < Time.time)
        {
            if (CrossPlatformInputManager.GetButtonDown("Disparo"))
            {
                GameObject Projectile = Instantiate(prefab) as GameObject;
                Projectile.transform.position = transform.position + Camera.main.transform.forward * 2;
                Rigidbody rb = Projectile.GetComponent<Rigidbody>();
                rb.velocity = Camera.main.transform.forward * shootSpeed;
                Destroy(Projectile, 2.2f);
                youCanShootNow = Time.time + coolTime;

            }

        }
    }
}

向射击脚本添加冷却时间
