Need help with my code

I coded a bullet shooting system and when I click it spawns a lot of bullets, Please help me



Heres My Gun code


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

public class Gun : MonoBehaviour
{
public float damage = 10f;
public float range = 100f;
public float fireRate = 15f;
public float impactForce = 30f;

public Camera MainCamera;
public ParticleSystem GunShot;
public GameObject impactEffect;
public GameObject bulletPrefab;

public Transform bulletSpawn;

public float bulletSpeed = 30;

public float lifeTime = 3;

private float nextTimeToFire = 0f;

// Update is called once per frame
void Update()
{
if (Input.GetButton("Fire1"))
{
Fire();
}



Heres my bullet code


using UnityEngine;

public class Bullet : MonoBehaviour
{
private void OnTriggerEnter(Collider other)
{
print("hit " + other.name + "!");
Destroy(gameObject);
}

}



if (Input.GetButton("Fire1") && Time.time >= nextTimeToFire)
{
nextTimeToFire = Time.time + 1f / fireRate;
Shoot();
}
}


private void Fire()
{
GameObject bullet = Instantiate(bulletPrefab);

Physics.IgnoreCollision(bullet.GetComponent<Collider>(),
bulletSpawn.parent.GetComponent<Collider>());

bullet.transform.position = bulletSpawn.position;

Vector3 rotation = bullet.transform.rotation.eulerAngles;

bullet.transform.rotation = Quaternion.Euler(rotation.x, transform.eulerAngles.y, rotation.z);

bullet.GetComponent<Rigidbody>().AddForce(bulletSpawn.forward * bulletSpeed, ForceMode.Impulse);

StartCoroutine(DestroyBulletAfterTime(bullet, lifeTime));
}

private IEnumerator DestroyBulletAfterTime(GameObject bullet, float delay)
{
yield return new WaitForSeconds(delay);

Destroy(bullet);
}

void Shoot()
{
GunShot.Play();

RaycastHit hit;
if (Physics.Raycast(MainCamera.transform.position, MainCamera.transform.forward, out hit, range))
{
Debug.Log(hit.transform.name);

Target target = hit.transform.GetComponent<Target>();

if (target != null) ;
{
target.TakeDamage(damage);
}

if (hit.rigidbody != null)
{
hit.rigidbody.AddForce(-hit.normal * impactForce);
}

GameObject impactGO = Instantiate(impactEffect, hit.point, Quaternion.LookRotation(hit.normal));
Destroy(impactGO, 2f);
}
}
}

 

What's your desired behavior?

 

Sorry I'm new to C# what does that mean?

 

It has nothing to do with C#. You said

So presumably "spawning a lot of bullets" is not what you want to happen. But it's hard to help you if you haven't explained what you actually want to happen. Do you want just a single bullet to fire per mouse click? Do you want a lot of them, but fewer than currently? Do you want something completely different to happen? Help me help you.

 

Ohhh, Ok so i realized what i did wrong but i still have one more thing, I want the bullet to go in a straight line instead of going straight down. like a normal pistol would do

 

You probably have gravity enabled on the rigidbody. Turn off gravity if you want it to go in a straight line.

Also, just watch out trying to use rigidbodies for bullets. Unless your game is cartoony, and the bullets are slow, you'll probably have a lot of cases where the bullets are going too fast and don't trigger colliders as you've expect. There's a whole bunch of threads on the forums of how to handle bullets.
