Question Virtual Touch zone to rotate camera (android)

I need some help the unity virtual touch zone included in the new standard assets,

what i want is to be able to drag the finger to rotate the camera.

the script from the standard assets work, kinda, but the camera doesn't stop rotating when the finger is stoped and still touching the screen, it works more like an invisible joystick than a touchzone

here is the script

pd: using the new input system, all tutorials use the old input class

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.EventSystems;
5. using UnityEngine.Events;

what do i need to change to make it more like a drag to rotate.?

 

How did you solve the problem?

 

Please don't necro-post to old threads assuming your problem is in any way related.

Instead, set yourself up for success by starting your own post... it's FREE!

When you post, remember nobody here can read your mind.

How to report your problem productively in the Unity3D forums:

http://plbm.com/?p=220

This is the bare minimum of information to report:

- what you want
- what you tried
- what you expected to happen
- what actually happened, especially any errors you see
- links to documentation you used to cross-check your work (CRITICAL!!!)

If you post a code snippet, ALWAYS USE CODE TAGS:

How to use code tags: https://forum.unity.com/threads/using-code-tags-properly.143875/

Camera stuff is pretty tricky... you may wish to consider using Cinemachine from the Unity Package Manager.

There's even a dedicated forum: https://forum.unity.com/forums/cinemachine.136/

 

I'm having this exact problem as well. The documentation around how to work with this is severly lacking, If you come up with a solution please let me know
