IMGUI

Currently with the imgui interface being implemented it starting to look like a game engine. Know I think i will be doing a full engine rewrite and only adding imgui later, not that it was hard but rather that I don't know how I would handle saving engine scenes, exporting the game to a executable with custom player scripts, and etc. Also I learned quite a bit on how abstraction works and that has lead me to first wanting to be able to make a game using this engine without any UI then in the future implementing the UI. But who knows everything might change and I might just learn fast enough to want to implement the UI before.

How did I learn?

I followed the getting started tutorial on LearnOpenGL. I highly recommend doing the exercises because they seem stupid but you learn so much from them.

Is this project finished?

No, its nowhere near finished I plan on implementing a ECS (Entity Component System) (Finished) and using ImGui to control the editor. I still have no idea on how I would approach building the game from the engine, collision detection, terrain generation, model loading into voxels, etc.

Should you learn opengl?

It depends on if you want to make a game within a year or two or if you want to spend 2 years on a engine then 1 year on a game. I personally want to make my own game engine I can use on any game. Therefore I am willing to spend 2 years making a game engine then using it on every game I make.
