Need help with my Code

Hey. I am trying to make a script that allows me to drag a object on x axis (which works)but for some reason it transforms on y axis... how to make that y axis would be locked i tried adding a rigidbody but the constrains are not working....
THIS IS MY SCRIPT FOR MOVING IT:

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class TouchControl : MonoBehaviour {
6.     float distance = 10;
7.     void OnMouseDrag()
8.     {
9.         Vector3 mousePosition = new Vector3 (Input.mousePosition.x, 250, distance);
10.         Vector3 objPosition = Camera.main.ScreenToWorldPoint (mousePosition);
11.         transform.position = objPosition;
12.  
13.     }
14. }  
15.  

Any help would be nice Thanks.. Happy Christmas

 

you should be passing the Input.MousePosition DIrectly in the ScreenToWorldPoint method, than when you apply that position to the object just ignore the z and y axis.

 

Could you simplify this for me cauz i'm kinda new to c#....Sorry

 

Code (CSharp):

1. using UnityEngine;
2.  
3. public class TouchControl : MonoBehaviour {
4.     private void OnMouseDrag() {
5.         Vector3 objPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
6.         transform.position = new Vector3(objPosition.x, transform.position.y, transform.position.z);
7.     }
8. }
9.  

also is a little more future proof but and requires more work, but the more optimial way would to to use the IDragHandler

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.EventSystems;
3.  
4. public class TouchControl : MonoBehaviour, IDragHandler {
5.     public void OnDrag(PointerEventData eventData) {
6.         Vector3 objPosition = Camera.main.ScreenToWorldPoint(eventData.position);
7.         transform.position = new Vector3(objPosition.x, transform.position.y, transform.position.z);
8.     }
9. }
10.  

but doing so also requires you to have a event system in your scene, and a physics raycaster on your camera to work.

 

Thanks!!!!!! <3

 

Yeah i just ran in to another problem the object i am trying to move when i click on it is transforming on x not to much just a bit(I can move it on x)..... and its kinda annoying...
