Hello, The tools for malie engine are listed here so it's not that I need help finding something for my specific game engine, but I was wondering if anybody would be able to help me actually understand how to use it? I apologise for being incompetent, I have never done this before and this seems like the best place to ask. I couldn't find any script data within my game's directory, (only data I could open using garbro was obviously just cg, sprites, audio, menu buttons and the like) so I assume the code listed is used to unpack that, I don't know how to download or use the GitHub link with so many folders of things I don't understand. If anybody could help, I would be very grateful thank you!
