Sorry, I think I've just found a new bug :)

I've tried to change the avatar Y starting position, and while it works in the box, the script preview doesn't refresh. After saving the script and exporting the game, it seems nothing had changed in the script. So I restarted the application then tried to change the script directly, which, oddly enough, seems only possible using the right click and copy/paste. I can't type anything in the preview at the bottom of the screen, but I can copy and paste stuff. Yet saving the script after modifying it this way doesn't seem to actually save it either.

No worries, thanks for finding it! :)

Fortunately this was a really quick fix. The main issue with the start position was related to a change to an underlying function I was relying on to print out the XYZ coordinate as a string to the script code. Long story short, it was putting parentheses around the coordinate which invalidated the script due to incorrect syntax - for example (2, 3, 4) instead of just 2, 3, 4 as it was previously doing.

Also, the other issue relating to editing the script preview appears to be a bug in the text edit UI component I am using. I actually have it marked as disabled/read-only since (at least for now) it's just to show you what the source code looks like, so the copy/paste needs to be disabled also. That would explain why it didn't save since it wasn't expected to be edited. :)

Thanks for the bug report! I'll have the start position fix in v0.3.4, and will look further into the copy/paste bug since that could cause confusion.
