Question by bommba · Feb 14, 2016 at 09:17 PM · scripting problemdrag-and-drop

Drag and Drop along X and Z-Axis

How can I make a Drag and Drop, where the object doesn´t move along the y-Axis. Online I had found this script: using UnityEngine; using System.Collections;

 public class drag : MonoBehaviour {
     Vector3 dist;
     float posX;
     float posY;
 
   void OnMouseDown(){
       dist = Camera.main.WorldToScreenPoint(transform.position);
       posX = Input.mousePosition.x - dist.x;
       posY = Input.mousePosition.y - dist.y;
 
     }
 
   void OnMouseDrag(){
       Vector3 curPos = 
                 new Vector3(Input.mousePosition.x - posX, 
                 Input.mousePosition.y - posY, dist.z);  
 
       Vector3 worldPos = Camera.main.ScreenToWorldPoint(curPos);
       transform.position = worldPos;
     }
 }

But how can I change it, that the Object moves along Z instead Y Axis?

Can you not just change all of the instances of "y" to "z," then go from there?

Try this one.

     public class Drag : BaseClass
     {
         Vector3 dist;
         Vector3 startPos;
         float posX;
         float posZ;
         float posY;
         void OnMouseDown()
         {
             startPos = transform.position;
             dist = Camera.main.WorldToScreenPoint(transform.position);
             posX = Input.mousePosition.x - dist.x;
             posY = Input.mousePosition.y - dist.y;
             posZ = Input.mousePosition.z - dist.z;
         }
 
         void OnMouseDrag()
         {
             float disX = Input.mousePosition.x - posX;
             float disY = Input.mousePosition.y - posY;
             float disZ = Input.mousePosition.z - posZ;
             Vector3 lastPos = Camera.main.ScreenToWorldPoint(new Vector3(disX, disY, disZ));
             transform.position = new Vector3(lastPos.x, startPos.y, lastPos.z);
         }
     }

thank you for this code, but when I add this to my object it's effecting only its in world pivot, my objects are rotated in a different way. Is there a possible way to use this code with its local pivot
