Enemy AI differently

Unity Engine
1

I have a question, I recently started programming in unity but three months and I do not know how to make “Enemy AI” I saw something in fps, but the tutorial was a bit different as I thought. So I want to ask if someone makes a script that does that for me to go after the enemy and I will shoot the dice.

give it a google!

this is what i came up with…

I’m using the same scripts in this tutorial for waypoints and enemy ai, but they won’t attach to any object. I’m following the tutorial (Unity 3d AI Tutorial 2 - OneWaypoint system), and it makes sense but it won’t do what its supposed to.
Waypoints:
var waypoint : Transform;
var speed : float = 20;

function Update () {
var target : Vector3 = waypoint.position;
var moveDirection : Vector3 = target - transform.position;

var velocity = rigidbody.velocity;

if(moveDirection.magnitude <1){
velocity = Vector3.zero;
}
else{
velocity = Vector3.forward * speed;
}

}

Enemy AI:
var waypoint : Transform[ ];
var speed : float = 20;
private var currentWaypoint : int;
var loop : boolean = true;

var player : Transform;

function Awake(){
waypoint[0] = transform;
}

function Update () {
if(currentWaypoint < waypoint.length){
var target : Vector3 = waypoint[currentWaypoint].position;
var moveDirection : Vector3 = target - transform.position;
var distFromPlayer : Vector3 = player.position - transform.position;

var velocity = rigidbody.velocity;
if(moveDirection.magnitude < 3){
currentWaypoint++;
}
else if(distFromPlayer. magnitude < 20){
velocity = Vector3.zero;
target = player.position;
velocity = (player.position - transform.position).normalized * speed;
if((player.position - waypoint[currentWaypoint].position).magnitude > 21){
target = waypoint[currentWaypoint].position;
velocity = moveDirection.normalized * speed;
}
}
else{
velocity = moveDirection.normalized * speed;
}
}
else{
if(loop){
currentWaypoint=0;
}
else{
velocity = Vector3.zero;
}
}

rigidbody.velocity = velocity;
transform.LookAt(target);

}

I have 3 problems in code.

nothing ?

My Guess is that there should be comments for the lines:
Waypoints: , EnemyAI:
It doesn’t mean anything pro-grammatically so it’s probably a comment.
//Waypoints:
//EnemyAI:

It is 2 scripts in one:
Waypoints.js
and
Enemy AI.js
Cut them.
