rotate object toward mouse code example

Example 1: how to make an object point towards the mouse in unity

//Inside your update loop, add the following code:

//First, get the mouse position
Vector2 mousePosition = new Vector2 ( 
  Input.GetAxis("MouseX"), 
  Input.GetAxis("MouseY")
);
//Then, use unity's built-in lookAt function to do all the math for you:
transform.LookAt(mousePosition);

Example 2: unity rotate towards mouse

using UnityEngine;     using System.Collections;          public class SCR_mouseRotation : MonoBehaviour {                  void Update () {             Vector3 mousePos = new Vector3(Input.mousePosition.x, Input.mousePosition.z, 10);             Vector3 lookPos = Camera.main.ScreenToWorldPoint(mousePos);             lookPos = lookPos - transform.position;             float angle = Mathf.Atan2(lookPos.z, lookPos.x) * Mathf.Rad2Deg;             transform.rotation = Quaternion.AngleAxis(angle, Vector3.down); // Turns Right                 transform.rotation = Quaternion.AngleAxis(angle, Vector3.up); //Turns Left                      }     }
