AI for 3rd person shooter

First start with a path-finding system so the enemy walks towards the player:

Then write a script that measures the distance between the enemy and the player. Ex.

var distance = Vector3.Distance(obj.transform.position, transform.position);

Then have the script make the enemy look at your player if the distance is less than the distance you want. Ex.

var Player : GameObject; var distanceTillShoot : float;

function FixedUpdate(){ var distance = Vector3.Distance(Player.transform.position, transform.position); if (distance <= distanceTillShoot){ gameObject.transform.LookAt(Player) }

}

Then after the enemy is looking at the player have it instantiate a bullet moving forward in the local axis. Make sure to create a bullet Prefab, probably just a small sphere with a collider and rigidbody attached. Ex.

var Player : GameObject; var Bullet : Rigidbody; var projectileSpeed : float; var distanceTillShoot : float;

function FixedUpdate(){ var distance = Vector3.Distance(Player.transform.position, transform.position); if (distance <= distanceTillShoot){ gameObject.transform.LookAt(Player) var bullet : Rigidbody=Instantiate(Bullet,transform.position,Quaternion.identity); bullet.rigidbody.AddRelativeForce(transform.forward * projectileSpeed); }

}

If you want a sniper or something just increase the distance till shoot variable. ...............................................................................................................................................................................

If your just starting out start with something simpler like a game where you have to dodge

balls or something. Making a Third Person Shooter or FPS isn't for the faint of heart, it takes much

understanding and execution of scripts and components to create one.
