Fine, ill do it myself – Over the past few months, I’ve been working on my own 3d game engine in C++. With the goal to build my own 3D Boomer Shooters but with modern 3D graphics APIs. In today’s episode I walk through how it all works, and how I’ve used open-source tools to make it happen. Please enjoy!

What you have so far reminds me of Selaco - a GZDoom boomer shooter that's a moody sci-fi tactical shooter that uses modern pbr materials and lighting but mostly voxels and 8 directional 2D sprites for enemies, weapon sprites and objects. I'd personally love to see this game go for that kind of look.

Where are the micro-transactions and how do i implement a constant online check? This engine needs to be fit for modern gaming.

But Mr MVG, what will you call your Engine? (Most) good engines have a sick name

Forgive me father MvG edition😂🎉

pretty much have built out my own game engine editor now. I was inspired years ago when Tim Sweeny said something along the lines of " if you don't want to pay the epic fee's make your own engine". Would love to have a convo sometime!

You're making skybox "box" huge and that's where you get that render artifact in the sky (limitation of depth buffer precision).
Instead - make a box small (1x1x1 meter) and draw it as a first thing (before the level). This way it'll cover any open portions of the map without any artifacts. Edit: do not forget to disable depth write when drawing the cube ))

Using dynamic_cast in a game is a big no no, obviously you didn't compile with -fnorrti :(.

Don't lie. This is a simple ray casting engine. Damn liars

i've love to learn about how you hooked opengl to your game.
(that way i can make a new hook for ut99)
@unrealengine1enhanced December 2, 2024 - 9:52 am
go full ut99 clone.

Very clever use of tiled. What are you using for visibility culling? I have built similar systems in other frameworks. Always love to see the retro concepts updated for modern systems.

I love graphics programming, I'm currently building a ray tracing engine in Vulkan for university and hoping to study an MSc in computer graphics next year
