Move a rotated object along it's X and Z-axis

Hi,

We made a script where we can drag and rotate objects with the mouse with an arrow. When the object is unrotated, this works good. After the object is rotated however, the object stil move along it's x an z position.
Unfortunately changing the transform.parent.parent.position to ....localPosition doesn't work.

Does anyone have a solution to this problem?


Thanks in advance,

Louis

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class MoveX : MonoBehaviour {
6.  
7.     private Vector3 mousePosition;
8.     private Vector3 currentMousePosition;
9.     private float distance;
10.  
11.     private void OnMouseDown()
12.     {
13.         currentMousePosition = Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y,
14.                                                               -Camera.main.transform.position.z));
15.  
16.         distance = currentMousePosition.x - transform.position.x;
17.     }
18.  
19.     private void OnMouseDrag()
20.     {
21.         mousePosition = Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y,
22.                                                        -Camera.main.transform.position.z));
23.  
24.        
25.         Vector3 distanceAsVector = new Vector3(distance, 0, 0);
26.         Vector3 mousePositionAsVector = new Vector3(mousePosition.x, transform.position.y, transform.localPosition.z);
27.         transform.parent.parent.position = mousePositionAsVector - distanceAsVector;
28.     }
29.    
30.  

 

Use the objects forward and right instead of world axis?

 

Hi FlashMuller,

Thanks for you're reply.
We've tried to use the vector3.forward, etc instead of the 0,0,blabla, but unfortunately without a good result.
Can you be a little more specific or does anyone has an other solution to this problem.


Thanks in advance,

Louis

 

multiply the objects rotation by your input.

 

I wanted to drop this in here earlier, too bad i don't have unity at work, haha

Code (CSharp):

1.         CamRigY.position += Quaternion.Euler(0,CamRigY.eulerAngles.y,0)//make WSAD relative to look rotation #Quaternion black magic
2.             * new Vector3(Input.GetAxis ("Horizontal"), 0, Input.GetAxis ("Vertical"))// move X by HRZ, move Z by VRT
3.             * moveSpeed * Time.deltaTime;

this snippet is from my RTS camera controller.
