unity rotate towards mouse 3d 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

Quaternion.RotateTowards(Quaternion from, Quaternion to, float maxDegreesDelta);

Example 3: 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                      }     }

Example 4: unity make 3d object spin towards mouse

public class LookTowardMouse : MonoBehaviour {      // Update is called once per frame     void Update ()      {                  //Get the Screen positions of the object         Vector2 positionOnScreen = Camera.main.WorldToViewportPoint (transform.position);                  //Get the Screen position of the mouse         Vector2 mouseOnScreen = (Vector2)Camera.main.ScreenToViewportPoint(Input.mousePosition);                  //Get the angle between the points         float angle = AngleBetweenTwoPoints(positionOnScreen, mouseOnScreen);          //Ta Daaa         transform.rotation =  Quaternion.Euler (new Vector3(0f,0f,angle));     }      float AngleBetweenTwoPoints(Vector3 a, Vector3 b) {         return Mathf.Atan2(a.y - b.y, a.x - b.x) * Mathf.Rad2Deg;     }  }
