Im looking for a way to make the enemies on my map move randomly around if the player isnt in distance… heres my AI script. Please and thank you :]

using UnityEngine;
using System.Collections;

public class EnemyAI : MonoBehaviour {
	public Transform target;
	public int moveSpeed;
	public int rotationSpeed;
	
	private Transform myTransform;
	
	void Awake() {
		myTransform = transform;
	}
	
	// Use this for initialization
	void Start () {
		GameObject go = GameObject.FindGameObjectWithTag("Player");
		
		target = go.transform;
		
	}
	
	// Update is called once per frame
	void Update () {
		
		float distance = Vector3.Distance(target.transform.position, transform.position);
		
		Debug.Log(distance);
		if(distance < 10 && distance > 2) {
		Debug.DrawLine(target.position, myTransform.position, Color.red);
		
			//look at target/rotate
			myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed * Time.deltaTime);
		
			//move towards target
			myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
			animation.Play("walk");

	}

		if(distance < 2) {

			animation.Play("attack");
					}

		if(distance > 10) {
			
			animation.Play("idle");
		}

	}
}

Hello convictcartel!

I’m not that good in C#, so I can’t write you a proper script for it to work, but I do know how to do this.

First off, you should be familiar with the Random class.

I’m unsure whether you want to teleport your enemies to random locations, or you simply want them to move to a random point nearby.

The later is fairly simple with your AI setup, and I assume that is what you want. Have a new variable called targetPos (or etc.), and make it normally equal to “target.position”. When the player is far enough from the enemy, set targetPos like so:

//Note: this makes them move in a random SQUARE, not a circle. //A circle would require an angular-radius system.

public float width = 5; //Your square width
float rx = Random.Range(-1,1);
float rz = Random.Range(-1,1);

targetPos = Vector3(transform.position.x+(rx*width), someYValue, transform.position.z+(rx*width));

This code is untested. Not only that, I’m not great in C#. Have your enemy move to targetPos instead of target.position.

If the enemy will always be far out of view when moving randomly (and traveling doesn’t matter), it will be much more optimal to teleport it. Doing so will vary greatly on the type of game you are making, so I will not post it here.

I bid you good luck, and I hope this helps!
