I know how to use packpanda fairly well and I’ve never had issues with it in the past. But if instead of creating an installer I wanted to create an updater that someone could run on their computer and just have it update the game for them – like if I caught a glitch post-production and I want them to be able to run the installer and have it fix the code, what would I need to do?

Panda has a built-in patching system. You can get the basics of it here: panda3d.org/manual/index.php … ng_patches

That page talks about making patches after you used ppackage or packp3d or something. I don’t know what any of that stuff is – all I know how to use is packpanda. How do I make an updater for something I made with packpanda?

packpanda isn’t designed for self-patching applications. You could probably do it, but it would be much easier just to build a completely new version of the application and ask your users to re-download and re-install it.
