Modular is more what’s on unity and unreal stores. I know they are a billion times bigger and
Modular in the sense whatever you are looking for is neark plug and play regardless of your games themes. There is even some crossover because 99% inventory systems are 2d and all player option menus are 2d.
So you would buy or use for free a system say for player options and just plug your variables and your art into it and boom you are done in like 20 minutes.
Great to see you posted the asset I’m not that much into 2d but I’m going to look at it. It seems extremely interesting and useful for the community.
I believe Gdevelop are creating ‘custom objects’ with their own code that could function as modular assets, people just need to create more I guess! Have you checked out custom objects?
Yes, custom objects really shine when it comes to being modular, so I recommend using them instead and do you JS implementations - even of rot.js - inside Custom objects or Extensions
The chest bug shouldnt be there, just create new world. It has been working perfectly fine for me for many different worlds. I think its just that particular chest/world that is buggy. Let me know if you encounter any other problems.
