How to Make An Assault Rifle Fire automatic?

Unity Engine
1

Hi! Me and a couple friends are planning to make a FPS game. We are somewhat new to Unity. I know some C#, but I was wondering how I can make he gun shoot at a certain pace (depending on the guns fire rate is how fast it would fire) and how I could just hold down the left mouse button and it will fire? Thanks!

pseudocode:

float fireRate = 0.2;
float fireTime = 0

Update()
{
    fireTime -= Time.deltaTime;

    if(attacking && fireTime <= 0)
    {
        fireProjectile();

        fireTime = fireRate;
    }
}

But don’t you need to instantiate the bullet?

you can use a co routine to delay the execution of firing.

void startFiring()
    {
        StartCoroutine("fireBullet",0.5f);
    }
    IEnumerator fireBullet(float delay)
    {
       //instaniate bullet function
        yield return new WaitForSeconds (delay);
        StartCoroutine("fireBullet",delay);
    }

Since in real life it’s nearly impossible to see bullets, they’re replaced with RayCast trace. For guns like rocket launcher, you’ll need to instantiate projectile.

fireProjectile() is a function which you have to define and put a shooting script into it.

Not advising you to “make a game like pong” first, but you must at least know how the engine works and how to do C# scripting.

Yeah but also in real life your bullet dosent make it to its location immedietly

This will it shoot without end while you use function startFiring
