Custom Game Engine

A lot of stuff, I had to rework my shader program system as well as fix my build system (CMake) in order for it to copy assets over. I had to import a library “whereami” to figure out where the binary file was according to the users file system, which let me discover the final assets. Not a lot content-wise. Greatly improved backend rendering.

I got inputs working and I can navigate my 3D environment (big steps)

Made a FPS counter and made sure to turn off vsync.

Woah. I finally got a 3d rotation triangle :O

We’ve come a long way (and i’ve been lazy) but I finally got texture rendering to work. I’ve also spent a lot of time organizing things into classes so complex behavior (like raw opengl calls) are abstracted away and I can speed up development in my game engine. Soon to go 3D!

I made the triangle go bigger and smaller, had to rework my shader system in order to support modifying vertex points. I also spent a lot of time abstracting mesh things into classes (vertex buffer objects, vertex array object) so it’s easier to use in the future and I don’t have to work with raw opengl calls every time.

note: you may notice that the scale of the triangle doesn’t increase/decrease orderly (uniformly increasing) this is because my scale code is being called in the render, which is for every frame. This issue is usually resolved by creasing “fixed updates”; like the minecraft tick system that runs game logic (not rendering).

Because I’m going to need extensive debugging logic, I decided to go with a GUI system (ImGui) after watching jdh’s video on his experience while creating a game engine. This is going to help me change values, etc, etc in the game engine, which is especially helpful for the (maybe) later on level editor.

Wow! I finally got a 2d triangle rendered on screen. (Even though my engine will be in 3d)

I built a simple custom logger for my project. I also had to make a seperate subdirectory (Core) for this. (I didn’t have to but ethe rway)

I fixed up my CMake config files and then implemented the window creation logic. (yes, blank window. no rendering yet)

I did a couple things:

• Setup CMake (first time using this) to easily compile and build my project, as well as automatically download glfw3 on the user’s computer if they dont’ already have it.
• Setup project in general (git, gitignore)
• I also forced myself to use Neovim to prevent accidental AI usage
