What's wrong with my AI script.
I have my script here but I don't know how to fix the error. /Scripts/AI.cs(37,35): error CS1501: No overload for method LookAt' takes
3' arguments
using UnityEngine;
using System.Collections;
public class AI : MonoBehaviour {
public int health = 100;
public Transform target;
public bool foundTarget = false;
public int movespeed;
public int rotateSpeed;
private bool takeDamage = false;
public Transform myTransform;
// Use this for initialization
void Start () {
takeDamage = false;
myTransform = transform;
target = GameObject.FindWithTag("Player").transform;
}
// Update is called once per frame
void Update () {
if(takeDamage == true)
{
health -= 10;
}
if(health == 0)
{
gameObject.SetActive(false);
takeDamage = false;
}
if(foundTarget && health > 0)
{
transform.LookAt(target.position.x, transform.position.y, target.position.z);
myTransform.Translate(Vector3.forward * movespeed * Time.deltaTime);
}
}
void OnTriggerEnter(Collider other)
{
if(other.gameObject.tag == "Bullet")
{
takeDamage = true;
}
if(other.gameObject.tag == "Player")
{
foundTarget = true;
}
}
void OnTriggerStay(Collider other)
{
if(other.gameObject.tag == "Bullet")
{
takeDamage = true;
}
}
void OnTriggerExit(Collider other)
{
if(other.gameObject.tag == "Bullet")
{
takeDamage = false;
}
}
}

Hey.
Your problem comes up because there is no method for LookAt that takes 3 arguments, which you are feeding it in the form of an x, y and z, coordinate. You need these to be given as one argument, i.e. a vector 3.
You can solve this in 2 ways I can think of. If you are trying to make it look at a GameObject (a target), save that target in a GameObject variable and simply write
transform.LookAt(target);
You might even be able to solve it with just this
transform.LookAt(target.gameObject);
Otherwise, you can just go ahead and write, which I think should solve it too. ´
transform.LookAt(vector3(target.position.x, target.position.y, target.position.z);
Good luck and have fun making games
$$anonymous$$inor addition: Since he's using C# the third option would have to be transform.LookAt(new Vector3(target.position.x, target.position.y, target.position.z);
Right. I tend to forget that as I work in Unity's "Javascript"
I ended up figuring out the problem before you guys posted the answers, but thank you for the help anyway.

LookAt takes a whole Vector3.. not the pieces of one.

You are not using the "LookAt" reference as intended, seeing it only takes 2 arguments. http://docs.unity3d.com/Documentation/ScriptReference/Transform.LookAt.html
So replace "transform.LookAt(target.position.x, transform.position.y, target.position.z);"
With:
"transform.LookAt(target);"
If you absolutely need to have the y of the current gameobject, you can simply do this:
if(foundTarget && health > 0)
{
target.position.y = transform.position.y;
transform.LookAt(target);
myTransform.Translate(Vector3.forward * movespeed * Time.deltaTime);
}
Your answer
