几年前我做了一个自顶向下的射手，我有一个类似的问题。尝试改变这个：

if(Input.GetButton("Fire1") && Time.time > nextTimeToFire)
        {
            nextTimeToFire = Time.time + fireRate;
            Shooting();
        }

从比较中去掉“=”，只把射速相加而不是相除。我当时就是这么做的。还有，你打算在枪重新装弹的时候做些什么吗？因为如果没有，它只是检查它是否在重新装弹，你可以这样做：

if !(isReloading)
{     
        if (currentAmmo <= 0)
        {
            StartCoroutine(Reload());
            return;
        }
        if(Input.GetKey(KeyCode.R))
        {
            Debug.Log("R key was pressed.");
            StartCoroutine(Reload());
            return;
        }

        if(Input.GetButton("Fire1") && Time.time > nextTimeToFire)
        {
            nextTimeToFire = Time.time + fireRate;
            Shooting();
        }
}

这是一个GunController脚本，可以做你想做的事情。增加了武器后坐力

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GunController : MonoBehaviour
{
    public GameObject bulletPrefab; // Prefab of the bullet
    public Transform bulletSpawn; // Spawn point for the bullet
    public float fireRate = 0.5f; // Rate of fire in seconds
    public float recoil = 10f; // Recoil force applied to the player
    public int magazineSize = 6; // Size of the magazine
    public float reloadTime = 1.5f; // Time it takes to reload the gun

    private int currentAmmo; // Current ammo in the magazine
    private bool isReloading; // Flag to check if the gun is being reloaded
    private float nextFire = 0.0f; // Time when the player can fire again

    void Start()
    {
        // Initialize the current ammo to the size of the magazine
        currentAmmo = magazineSize;
    }

    void Update()
    {
        // Check if the player has pressed the fire button and if it's time to fire again
        if (Input.GetButton("Fire1") && Time.time > nextFire && !isReloading && currentAmmo > 0)
        {
            // Set the time when the player can fire again
            nextFire = Time.time + fireRate;

            // Create a bullet at the spawn point
            var bullet = (GameObject)Instantiate(bulletPrefab, bulletSpawn.position, bulletSpawn.rotation);

            // Add force to the bullet
            bullet.GetComponent<Rigidbody>().AddForce(bullet.transform.forward * 500);

            // Apply recoil force to the player
            GetComponent<Rigidbody>().AddForce(-transform.forward * recoil, ForceMode.Impulse);

            // Decrement the current ammo
            currentAmmo--;
        }

        // Check if the player has pressed the reload button and if the gun is not being reloaded
        if (Input.GetKeyDown(KeyCode.R) && !isReloading)
        {
            // Set the reload flag to true
            isReloading = true;

            // Start the reload coroutine
            StartCoroutine(Reload());
        }
    }

    IEnumerator Reload()
    {
        // Wait for the reload time
        yield return new WaitForSeconds(reloadTime);

        // Set the current ammo to the size of the magazine
        currentAmmo = magazineSize;

        // Set the reload flag to false
        isReloading = false;
    }
}

这个脚本应该附加到代表枪的游戏对象上。这个脚本有几个公共变量可以自定义：

• bulletPrefab是将要发射的子弹的预制件。
• bulletSpawn是表示子弹的产生点的游戏对象的变换组件。
• fireRate是以秒为单位的射速。这决定了火炮可以发射的频率。
• recoil是当枪发射时施加到玩家的后坐力。
• magazineSize是杂志的大小。这决定了枪能装多少子弹。
