UndertaleModTool VS awesome-gamemaker

UndertaleModTool although made for modding Undertale and Deltarune, it works with most game maker games. Just open the data.win file with it and you now have access to most of the game's code, sounds and sprites. Look for spritemaps/texturemaps and edit those. Just use it for modding and having fun and don't do anything illegal with it.

The naming screen script does not decompile correctly in UndertaleModTool, so you'll need to replace with a fixed version and then be careful not to trust any re-decompiled output. The others... that's just automatic line break messing you up. You probably have to rearrange the text so it fits better, maybe even add extra textboxes if you can't fit the translation.

You don't need GameMaker. You need UndertaleModTool, which can edit most game assets (rooms, code, strings) in a self-contained manner and export the rest (sprites, sounds) for external editing. Download a GUI build (it doesn't really matter which) from here: https://github.com/krzys-h/UndertaleModTool/releases

Thanks! This works. I download from here (picked this version, "GUI-windows-latest-Release-isBundled-true-isSingleFile-true.zip",idk what's the difference between them)

Tool Link: https://github.com/krzys-h/UndertaleModTool Yep, its an undertale tool, no joke. But its advertised as for multi-GM titles. though think I'm the first known one to use it on KZ lol or maybe not who knows.

you can use the deltarune mod tool to export all sprites from the data.win file

Everything is in game.unx, which is the same as data.win for Windows. You can dump certain asset types using UndertaleModTool, which has a Windows version (which oughta work through Wine) and a cross-platform CLI version. Download

After you've made a couple small games on your own - without being dependent on tutorials that handhold you through the process, that is - you should be able to pretty easily read and modify the decompiled code generated by UndertaleModTool after opening Undertale's/Deltarune's data file in it: https://github.com/krzys-h/UndertaleModTool

if it's a newer one like Undertale or Deltarune use UndertaleModTool

I'm in love with Gamemaker, which got me interested in programming: https://gamemaker.io

My 9-yo son has been making games with GameMaker https://gamemaker.io/

It's a popular framework for creating 2D HTML games and publishing them on sites like Crazy Games.

GameMaker has a lot of great tutorials and templates that makes it easy to get up and running. I usually just set him up with one of the existing game templates and let him loose on customizing the characters using the built-in tools. Then I help him customize the game interactions. GameMaker has two modes: one for visual flow editing and one for directly editing the code. It's a great onramp to learning to code with a super low barrier to entry.

I started my hobby game development journey with Game Maker Studio - https://gamemaker.io . Now I've switched to Godot for its simplicity and rich set of advanced features to actually build almost AAA games? if that's a thing.

Many popular game engines use this tiered approach including Unity, Unreal Engine, and Game Maker. However, many free and open-source software engines are released under the permissive MIT license.

Assuming you don't have any prior programming experience, since your goal is Undertale modding it might be best to start by learning how to use GameMaker (with the GML programming language, not the drag-and-drop): https://gamemaker.io
