@AntiDroid You need to package the required libraries in the click. This is how I do it for Neverball: https://gitlab.com/abmyii/neverball-touch/-/blob/master/clickable.json#L43-58
The method I use to identify them is just trial-and-error. I assume it runs on your device because you have the libraries already installed, whereas most devices don't have those libraries preinstalled.
@kugiigi What you could try is to use the libraries packaged with Neverball when running the game manually, since it should have most (if not all) of the required libraries. To do that, run:
And then run SuperTuxKart manually as you did before.
