Drag and Drop only on x and z axis?

Hello

I used this script to do a drag&drop and it is working onx,y,z.

Code (CSharp):

1. public class Dragit : MonoBehaviour {
2.     Vector3 dist;
3.     float posX;
4.     float posY;
5.  
6.     void OnMouseDown(){
7.         dist = Camera.main.WorldToScreenPoint(transform.position);
8.         posX = Input.mousePosition.x - dist.x;
9.         posY = Input.mousePosition.y - dist.y;
10.  
11.     }
12.  
13.     void OnMouseDrag(){
14.         Vector3 curPos =
15.             new Vector3(Input.mousePosition.x - posX,
16.                 Input.mousePosition.y - posY, dist.z);
17.  
18.         Vector3 worldPos = Camera.main.ScreenToWorldPoint(curPos);
19.         transform.position = worldPos;
20.     }
21. }

But i would like to move the gameobject only on the x and z axis and i don't get it. Could anybody helo me with that?

Might I recommend using a Vector3 instead of 2 floats? Here is my solution:

Code (CSharp):

1. Vector3 dist;
2.  
3. void OnMouseDown(Vector3 _pos)
4. {
5.       dist = Camera.main.WorldToScreenPoint(transform.position);
6.       Vector3 pos = new Vector3 (_pos.x - dist.x, transform.position.y, _pos.x - dist.x);
7. }

your OnMouseDrag method looks good.

Sorry if this does not work I am in school and can't test it on unity.

last shouldn't it be "_pos.y - dist.y" at the z Value of the vector3 ?

Code (CSharp):

1.  Vector3 pos = new Vector3 (_pos.x - dist.x, transform.position.y, _pos.y - dist.y);

so you can move x and z with 2 axis ?

 

I believe I just had a brain fart.
