New Input System Integration Script (Issues in Mobile touch) Custom_MousePosition

edited May 2021 in Technical Q&A

Hi! The script work amazing on PC, everything (all gamepad, keyboard, buttons, etc) but when I run my game on mobile, I have this error and I don't know how to fix it. (I have the last AC and the script from the wiki community)

(I have direct movement. I use a virtual gamepad)

NullReferenceException: Object reference not set to an instance of an object

AC.InputSystemIntegration.Custom_MousePosition (System.Boolean cursorIsLocked) (at <7937ef364f124b66a741c082746b1a41>:0)
AC.PlayerInput.InputMousePosition (System.Boolean _cursorIsLocked) (at :0)
AC.PlayerInput.UpdateInput () (at :0)
AC.StateHandler.Update () (at :0)

Thanks in advance,


  • For now I just comment some lines in the Input system integration and it work, but i know that is not the correct solution

    in Custom_MousePosition

    //return Mouse.current.position.ReadValue();


    case 0:
    return false;
    //return Mouse.current.leftButton.isPressed;

    case 1:
    return false;
    //return Mouse.current.rightButton.isPressed;

    and the same in


    IT work for me , but I don't know how to solve the null object to Mouse.current

  • Are you getting this error in the Editor, or a build?

    If you're in a build, the mouse input functions should not be called if your game's "Input method" is set to "Touch Screen".

    There's no problem changing the script in the way you have, however - it should be treated as a sample script to use as a basis for your own needs.

  • Thanks a lot! The script is very useful! And work great for me.
