Hello,

I want to know how to do zombie ai for my game. What is the best way to go about it?
What are all the steps you have to take? All i need is for the zombie to come a to life each round and try and kill me. I also need it to be able to die when shot at.

Thanks for any advise, and thing you know would help like tutorials or personal advise :slight_smile:

For the AI to make something follow you, you want to use something like this script I wrote:

function Update() {
enemy.transform.LookAt(target);
enemy.transform.position = Vector3.Lerp(
enemy.position, target.position,
Time.deltaTime * moveSpeed);
}
Then you want to use the variables:

var target : Transform;
var enemy : Transform;
var moveSpeed : float = 5.0;
You can select the items as the target and the enemy (which chances are is the gameobject the script is attached to) in the unity Inspector view under the script options. The complete script should look something like this:

var target : Transform;
var enemy : Transform;
var moveSpeed : float = 5.0;

function Update() {
enemy.transform.LookAt(target);
enemy.transform.position = Vector3.Lerp(
enemy.position, target.position,
Time.deltaTime * moveSpeed);
}
PS: If you don’t understand what i’m talking about you should start with something easier.

Also learn about Vector3s and Vector3.Lerp. You can read up about Vector3’s HERE and Vector3.Lerp HERE.

For the more realistic zombie part you can also use triggers for if he can sense you or not, and use animations to make it fancy!
