Shotgun Spread Issue

Questions & Answers

Hello, Im trying to make a shotgun script but im failing at making the bullets spread. The bullets instantiate fine but they go on the same direction, anyone has any idea how to fix this ?

Here is my code :

function Update()
{
var hit : RaycastHit;
	var forward = transform.TransformDirection(Vector3.forward);
	
	forward.x += Random.Range(-spreadRate, spreadRate);
	forward.y += Random.Range(-spreadRate, spreadRate);
	forward.z += Random.Range(-spreadRate, spreadRate);
	
	if(Physics.Raycast(transform.position, forward, hit))
	{
		if(Input.GetButton("Fire1") && canShoot==true && playerSettings.shotgunBullets > 0 && shotgun.gameObject.active == true)
    	{
       		var bulletInstance : Transform;
       		var bulletInstance2 : Transform;
        	bulletInstance = Instantiate(bullet, barrelEnd.position, transform.rotation);
        	bulletInstance2 = Instantiate(bullet, barrelEnd.position, transform.rotation);
        	bulletInstance.LookAt(hit.point);
        	bulletInstance2.LookAt(hit.point);
        	playerSettings.shotgunBullets -= 1;
        	w();
        	//shotgun.animation.Play("Shoot");
        	audio.PlayOneShot(soundEffect);
    	}
}

The bullet HAS to be a prefab!

Thank you for your time!

Edit : The bullet script :

#pragma strict

var bulletSpeed : float = 10;

function Awake()
{
	Destroy (this.gameObject, 5);
}

function Update()
{
	transform.Translate(Vector3.forward * Time.deltaTime * bulletSpeed);
}

function OnCollisionEnter()
{
	Destroy (this.gameObject);
}

Your bullets needs to have a LookAt target that has the spread value added to it in order to change their direction.

Check the code below:

function Update()
{
var hit : RaycastHit;
    var forward = transform.TransformDirection(Vector3.forward);
 
    if(Physics.Raycast(transform.position, forward, hit))
    {
        if(Input.GetButton("Fire1") && canShoot==true && playerSettings.shotgunBullets > 0 && shotgun.gameObject.active == true)
        {
               var bulletInstance : Transform;
               var bulletInstance2 : Transform;
            bulletInstance = Instantiate(bullet, barrelEnd.position, transform.rotation);
            bulletInstance2 = Instantiate(bullet, barrelEnd.position, transform.rotation);

    forward.x += Random.Range(-spreadRate, spreadRate);
    forward.y += Random.Range(-spreadRate, spreadRate);
    forward.z += Random.Range(-spreadRate, spreadRate);

            bulletInstance.LookAt(hit.point + forward);
            bulletInstance2.LookAt(hit.point + forward);
            playerSettings.shotgunBullets -= 1;
            w();
            //shotgun.animation.Play("Shoot");
            audio.PlayOneShot(soundEffect);
        }
}

Note: It’s assumed that you move bullets based on their LookAt.
