Rapid fire script?

Questions & Answers
1

Hello, I using the following script to launch my projectile on my game. When I click down, it fires on projectile. How can I make it so that when I hold down the mouse, the projectile continuous the fire (rapid fire, like a machine gun)? Thank you.

var projectile : Rigidbody; 
var speed = 20; 
function Update() 
{ 
 if( Input.GetButtonDown( "Fire1" ) ) 
 { 
  var instantiatedProjectile : Rigidbody = Instantiate( 
   projectile, transform.position, transform.rotation ); 
  instantiatedProjectile.velocity = 
   transform.TransformDirection( Vector3( 0, 0, speed ) ); 
  Physics.IgnoreCollision( instantiatedProjectile. collider, 
   transform.root.collider ); 
 } 
}

all you need to do is:

instead of

if(Input.GetButtonDown("Fire1"))

you need to do 

if(Input.GetButton("Fire1"))

that last one check every frame if you are holding down the Fire1 button (left mouse)

here's what you could try:

var projectile : Rigidbody;
var speed = 20;
var savedTime = 0;

function Update()
{  

 var seconds : int = Time.time;
   var oddeven = (seconds % 2);
   if(oddeven)
   {
     Shoot (seconds);
   }

}

function Shoot(seconds)
{
 if(Input.GetButton( "Fire1" ))  
 {   
  var instantiatedProjectile : Rigidbody = Instantiate(   
         projectile, transform.position, transform.rotation ); 
  instantiatedProjectile.velocity =
             transform.TransformDirection( Vector3( 0, 0, speed ) );
  Physics.IgnoreCollision( instantiatedProjectile. collider,
                                      transform.root.collider );  
 } 
}

you could play with the values, like the var "oddeven"

or if that isn't what you want, just get rid of the var oddeven, and in the 

if(oddeven)
       {
         Shoot (seconds);
       }

change it to 

if(seconds)

If unity3_users script is hard to get working correct you can look at this question: http://answers.unity3d.com/questions/12593/first-person-shooter-help/12619#12619

I gave a script there, And I think it might be a little but easier to use.

look up Time.time in the documentation. It will give you this, a much simpler solution than the other one.

var projectile : GameObject;
var fireRate : float;
private var lastFire : float = 0;

function Update()
{
     if(Input.GetButton("Fire1") && Time.time > lastFire)
     {
          lastFire = Time.time + fireRate;
          Instantiate(projectile, transform.position, quaternion.identity);
     }
}

ok, so here is my solution for shot timing, muzzle flash timing, and audio timing.
This script is in C#, hope you know that language…

using UnityEngine;
using System.Collections;


public class gun : MonoBehaviour {
	
	//Author : Electric Fountain Studios
	//Variables
	public float bulletsLeft;
	public float bulletImpulse = 100.0f;
	public float reload;
	public float bulletCount = 30;
	public float reloadTimer = 0.1f;
	public float ShotTimer = 0.01f;
	public float bullet = 1.0f;
	public float timeToReloadPoint = 0.0f;
	public float audioVolume = 5.0f;
	public float nextFire = 0.0f;
	
	//Game Objects
	public GameObject gun_prefab;
	public GameObject muzzle_flash;
	public GameObject bullet_prefab;
	
	//Audio
	public AudioClip shootSound;

	
	float theBullet;
	
	void Start () {
		bulletCount = bulletsLeft;
	}
	
	
	void Update () {
		if( Input.GetButton("Fire1") && Time.time > nextFire) {
			
			//Time
			nextFire = Time.time + ShotTimer;
			
			//Shooting Action
			GameObject theBullet = (GameObject)Instantiate(bullet_prefab, gun_prefab.transform.position, gun_prefab.transform.rotation);
			theBullet.rigidbody.AddForce( gun_prefab.transform.forward * bulletImpulse, ForceMode.Impulse);
			
			//M4 audio
			audio.PlayOneShot(shootSound , audioVolume );
			
			//M4 Muzzle Flash
			Instantiate(muzzle_flash, gun_prefab.transform.position, gun_prefab.transform.rotation);
			
			
			
			
			
		}
		if( Input.GetButtonDown("Fire1") ) {
			
			bulletsLeft = bulletCount - bullet;
		
			
		}
			
			if(bulletsLeft != timeToReloadPoint ){
					print("Need To Reload");
				
			}
		}
		
	
	
		
		
			
       		 	
}
