Hello, i’m trying to do a code to player look at mouse, but i’m a beginner and don’t know how to do it exatly, here is my code:

using UnityEngine;
using System.Collections;

public class PlayerBehaviour : MonoBehaviour {

	public Transform target;

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {

		transform.LookAt(target);
	
	}
}

I need to put mouse in target, but how? Or i need to do other code? Somebody can save me with that? I’m using C#, thanks =(

And sorry for my bad english

Try this:

void Update() {
    Vector3 dir = Input.mousePosition - Camera.main.WorldToScreenPoint(transform.position);
    float angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
    transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
}

You need to get the mouse position relative to the game screen, and always on Update function make your character turn around looking the mouse pointer.
