I am getting a Program Error: cannot read properties of undefined (reading: vtable) Just wondering what variable and where the error occurs.

Here is the game:

Wow, I looked really hard, but I couldn’t find anything…

Maybe, just maybe (don’t take this seriously if it sounds dumb I’m just a newb) check the \*_postion_ function. I don’t know but I think it might be that.

I like chess 🙂

Debug menu is great for this! It looks like the on game update is running _before_ the sprites were created. Perhaps you could implement a few seconds delay or have the on game update block not run if the game has been running for less than 300 milliseconds or so.
