Is there any way to use HTML in g develop it would make everything really easy
If you refer to using only HTML to do logic and stuff I think No,
If you mean using some thing from HTML such as having [div] or [h1] in Text I think maybe it can be added by some ways.
From what I understand:
Using Only HTML can’t do anything much for making a game, HTML is only for texts and just structures and how to represent of what are stored in the file.
When making games we need some logics to run and proceed in this case Gdevelop needs Javascript to do logical stuff and deal with variables.
Only thing that looks like HTML the most that I’ve seen in GDevelop is BBText object you can add [tags] to change the text style such as [b] for bold.
