How to limit the players rate of fire?

Questions & Answers
1

Hey,

I’m working on a space shooter and right now the player can shoot as fast as you can push the space bar and I just wanted to know how I would go about changing my script to limit the players rate of fire. All I have right now is just a basic piece of code that fires a bullet prefab, and the bullet prefab moves up the screen and checks for collisions with enemies then adds score.

this is what I have right now for the player shooting:

If (Input.GetKeyDown(“space”)){

var tempBullet: Rigidbody;

tempBullet = Instantiate(bullet, transform.position, transform.rotation);

}

How would I limit this?

Any help is appreciated :slight_smile:

Thanks.

try this

private var allowfire : boolean = true;
var tempBullet: Rigidbody;

function Update()
{
	if((Input.GetButtonDown)&&(allowfire))
	{
		Fire();
		
	}
	
}

function Fire()
{
	allowfire = false;
	tempBullet = Instantiate(bullet, transform.position, transform.rotation);
	yield WaitForSeconds(rate with which you want player to fire);
	allowfire = true;
}

it have fire rate and prass space

var tempBullet : Rigidbody;
var fireRate = 0.5;
private var lastShot = 0.0;

function Update()
{
    If(Input.GetKeyDown("space"))
    {
        Fire();
    }
}

function Fire()
{
    if (Time.time > fireRate + lastShot)
    {
        tempBullet = Instantiate(bullet, transform.position, transform.rotation);
        lastShot = Time.time;
    }
}

Try This
{
public float speed;
public GameObject shot;
public Transform shotSpawn;
public float fireRate;
private float nextFire;

void Update ()
{    
	if(Input.GetButton("Fire1")|| Input.GetKeyDown(KeyCode.Space)&& Time.time > nextFire)
	{
		nextFire = Time.time + fireRate;
		Instantiate(shot, shotSpawn.position, shotSpawn.rotation);
		GetComponent<AudioSource>().Play();

		}
}

}

using UnityEngine;
using System.Collections;

public class ShootBullets: MonoBehaviour {
	
	public GameObject spawnPoint;
	public Rigidbody projectilePrefab;
	public float speed;
	public float fireRate = 1.0f;
	private float lastShot = 0.0f;

	void Update ()
	{
		if (Input.GetButtonDown("Fire1"))
		{
			if (Time.time > fireRate + lastShot) {
			Rigidbody hitPlayer;
			hitPlayer = Instantiate (projectilePrefab, transform.position, transform.rotation) as Rigidbody;
			hitPlayer.velocity = transform.TransformDirection (Vector3.forward * speed);
			lastShot = Time.time;
		}
	}
}
}

This code works perfectly for me. It allows for the speed of the projectile to be changed as well as the fire rate. The only thing I noticed was that the player cannot shoot immediately once the game is started. Minor setback, however, I am interested in figuring out a way to allow the player to shoot once the game starts, and THEN be limited.
