Writing weapon imprecision

Im creating a top-down 2D shooter game.
I want my weapons to not shoot perfectly where I aim, but rather have a public float precisionthat goes from 0 to 100.
Bullets then have a random side deviation from a minimum angle to a maximum angle based on the precision amount. And the bullet should also rotate accordingly based on shoot angle.

I’ve been trying to do this for days to almost no avail. I’m very new to Unity and don’t really understand how Quaternions and stuff work.

This is my code right now:

float lastFire;
public virtual void Fire()
    if (Time.time > (lastFire + fireRate))
          var bullet = Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
          var rb = bullet.GetComponent<Rigidbody2D>();

          // Shoot bullet
          rb.AddForce(firePoint.right * projectileSpeed, ForceMode2D.Impulse);

         lastFire = Time.time;

Any ideas?

You can use Random.insideUnitCircle to get a random Vector2 direction. This will act as your offset. Multiply that by the precision amount and you should get a random deviation of a certain amount depending on the level of precision you set. For example:

// The lower the precision, the less offset there is
Vector2 offset = Random.insideUnitCircle * Precision;

// Adding the vectors together results in bullet deviation
rb.AddForce(firePoint.right + offset, ...);

Hope that’s what you asked for. @iKebab897
