I guess there's this Gruedorf thing, may as well participate and hopefully have motivation/accountability on this project.
I'm not working on a game yet, just a game engine that I have code named "Nebula 3" which is my 3rd complete re-write that I've named Nebula, probably my 10th rewrite of a game engine in total, over the course of something like 7 years or so, but this one is the final rewrite I'm sure.
Basically Nebula 3 is a 3D game engine that uses an ECS(Entity Component System) under the hood this time, which I got pre-canned in the form of Flecs. Flecs lets me focus less on how to store objects in the world and more on functionality, which is great because all my previous iterations had 3d functionality working, but not a very good method of storing entities in the world.
Currently in addition to the ECS, I have Lua scripting working, and I've implemented a basic OpenGL renderer for now, and I even have input binding, and text input working. With a working console even.
There is a separate rendering and update loops, with all Lua calls for the input being handled in the Update loop due to some quirks with the ECS system not liking things changing while it is running the systems.
In addition, Unicode support is a thing that actually sort of works too, character input is given as UTF-32, converted to UTF-8, then back to UTF-32 to render the text, tested with Japanese, only issue is switching fonts to support the characters needed.
I can't show any screenshots as I found out that for some reason my full screen OpenGL window doesn't show up in screenshots, so I guess I'll need to implement in engine screenshotting capabilities, which was already planned, just moves the timeline up a bit.
Plus before the screenshots can be captured, I have another segfault to deal with, this time I believe caused by attempting to load things onto the GPU in the update thread, I need to queue items that need to be loaded to the GPU to be done on the render thread instead of the update thread. This was caused by re-arranging things to be done completely from Lua scripts instead of hardcoded C++.
Next steps include: fixing above mentioned bugs, working further on UI elements, and porting over old 3d rendering and model loading code from older projects,
The UI is planned to be "done" with an in-engine editor in a working state by the end of March 2021. With an in-engine console with console commands counting as an editor.
