ARCore - Lean touch - Move object in X and Z axis (I want to Lock Y axis)

Hi,
I have created object moving app using ARCore. for object move purpose I have used Lean touch it works fine, But I want to lock axis Y it's overlapping my ground plan.
Please help to solve this issue.
Thanks in advance.

If you r using lean touch translate script then its really easy to clamp the y movement, just open the script and swap the y and z components. I have done it and if u need the edited script the just ping me .

 

Hi @Atulyextel2
Can you please show us how did you do that? I'm a beginner and I would like to see how did you do that change.

Thank you.

 

Hey @Atulyextel2 - I'm looking to figure this out as well. Would love to see the edits you have for the script! Thanks.

 

Hi,
sorry, bro replying late. first, u have to use the latest version of lean touch.
just change the LeanTranslateSmooth.cs script of lean touch with below code and the use LeanTranslateSmooth.cs script to translate. all the code is same as LeanTranslateSmooth script but I have just done few adjustments, I have commented my changes. best of luck and let me know if this works for u...

Code (CSharp):

1. using UnityEngine;
2. namespace Lean.Touch
3. {
4.     // This script allows you to transform the current GameObject with smoothing
5.     public class LeanTranslateSmooth : LeanTranslate
6.     {
7.         [Tooltip("How smoothly this object moves to its target position")]
8.         public float Dampening = 10.0f;
9.         // The position we still need to add
10.         [HideInInspector]
11.         public Vector3 RemainingDelta;
12.         protected virtual void LateUpdate()
13.         {
14.             // Get t value
15.             var factor = LeanTouch.GetDampenFactor(Dampening, Time.deltaTime);
16.             // Dampen remainingDelta
17.             var newDelta = Vector3.Lerp(RemainingDelta, Vector3.zero, factor);
18.             // Shift this transform by the change in delta(Atul`s change)
19.             Vector3 moveMe = (RemainingDelta - newDelta);
20.             moveMe.z = moveMe.y;
21.             moveMe.y = 0f;
22.             Debug.Log("move me : " + moveMe);
23.             //transform.position += (RemainingDelta - newDelta);
24.             transform.position += moveMe;
25.            // Debug.Log("pos : "+transform.position);
26.             // Update remainingDelta with the dampened value
27.             RemainingDelta = newDelta;
28.         }
29.         protected override void Translate(Vector2 screenDelta)
30.         {
31.             Debug.Log("HI!!!!SSSS");
32.             // Make sure the camera exists
33.             var camera = LeanTouch.GetCamera(Camera, gameObject);
34.             if (camera != null)
35.             {
36.                 // Store old position
37.                 var oldPosition = transform.position;
38.                 // Screen position of the transform
39.                 var screenPosition = camera.WorldToScreenPoint(oldPosition);
40.                 // Add the deltaPosition
41.                 screenPosition += (Vector3)screenDelta;
42.                 // Convert back to world space
43.                 var newPosition = camera.ScreenToWorldPoint(screenPosition);
44.                 // Add to delta
45.                 RemainingDelta += newPosition - oldPosition;
46.             }
47.         }
48.     }
49. }

 

@Atulyextel2 Thank you so much, it works perfectly!

 

@Atulyextel2 and for limit te rotation only in Y axis?
Can you help me?
Thanks!!!

 

@Atulyextel2 thanks for this, beast!

 

@Atulyextel2
Thank You!! I am using ARCore as well, is it possible to clamp the movement according to the "detected plane"? since ARCore needs to detect the plane first in order to generate usable plane[/QUOTE]

 

Works well,but.... only if you don´t move. If you move to your left and then you try to move the object the system of coordinates becomes crazy. I guess it only works if you are in the same position/ orientation of the world system of coordinates. Do you know how to fix it? because I am really tried of trying.
Thanks

 

If anyone is having trouble using this in a case @F_A_Duque7 mentioned, just comment the 20th line (moveMe.z = moveMe.y

 

@Kerber996 Thank you! Saved me hours of hunting!

 

helou, my name is Alison someone knows how to lock the z axis in unity with augmented reality
