What are you trying to make? I’m not aware of anything open source.
I think short of using rpgmaker (not open source) or something like it (that makes a very specific kind of game and you are really just plugging in content) you aren’t going to get very far into game development with no coding at all.
Unity (again not open source) allows you to do a lot without coding, but by the time you learn how to use Unity you may as well follow their provided education/classes and learn to code while you’re at it.
I would like to make something like a visual novel, a point and click adventure, text based game, or something like that but i may be dreaming too big. so what your saying is unity is probably my best bet?
Unity is not the easiest engine to learn by a long shot, I was really just using it as an example because they have a very good (and free) “learn to code in Unity” program.
It sounds like others have given some better starting points for you to look at for what you are looking to do, Unity seems a bit overkill.
It’s more for CYOA-like games, but Twine is pretty good and has a graph-like editor. Of course, if you want to do anything more complicated than “if (choice) go (page)”, you might need some code. But for the basics it works without.
