Question by Nightslashs · Aug 18, 2014 at 09:19 PM · camera-movement

How can we get the camera to find the mouse position and then point the camera at the poistion

using UnityEngine; using System.Collections;

public class MouseFollower : MonoBehaviour {

 public float renderDepth = 10.0f;

 void Start () {

     Screen.showCursor = false;

     if(rigidbody) {
         rigidbody.freezeRotation = true;
     }
 
 }
 
 void Update () {
     var mousePos = Input.mousePosition;
     var wantedPos = Camera.current.ScreenToWorldPoint(Vector3(mousePos.x, mousePos.y, renderDepth));
     transform.position = wantedPos;    
 
 }

}

thats the current code we are using but it isnt quite working we keep getting errors and dont know why. Thank you for any and all help :D

by any chance, are you trying to move the camera with your mouse movement? like an FPS would?

This is a great third person cam. http://wiki.unity3d.com/index.php?title=$$anonymous$$ouseOrbitImproved

You are moving the camera to that position. To just look at that position, change the last line to:

   transform.LookAt(wantedPosition);


If you are looking to move the camera (rather than rotate the camera), let me know.

You need a 'new' in front of the Vector3() on line 15. The line should be:

   Vector3 wantedPos = Camera.current.ScreenToWorldPoint(new Vector3(mousePos.x, mousePos.y, renderDepth));

Note I've changed 'var' to Vector3, though var will work.

The new line should be:

   transform.LookAt(wantedPos);
