I am almost certainly going to add some kind of programmable computer to my game. Thinking of making it programmable with assembly and basically implementing something like a 6502 VM that runs a handful of instructions per game tick. But I'm not entirely sure whether to make it an *actual* 6502, or to just make a similar but simplified ISA

Kinda tempted to do the second one, because 1) making ISAs is fun and 2) standard 6502 assembly is ugly so I'd wanna make some changes anyway.. #gamedev

I recently re-implemented my asset import system to make it much more flexible. Instead of having each tile variation in its own PNG, I can now make a tile set as one image. I can reference either the whole thing as a tile's texture to make it animated, or I can reference individual "frames" to have multiple tile textures in one image. Makes things like this way easier... #gamedev

I added hot reloading of C++ gameplay code to my game :D

This is possible because "engine" code and "gameplay" code is split into different shared libraries. So when you hit F5, it compiles a new shared library for the gameplay code and loads the new one (as well as reloading all the assets etc).

Kind of an obscure talk, but if you find #3D lighting and/or Overwatch interesting, you might enjoy this talk. The debugging tools were neat to see.

They started work on overhauling the global illumination before Overwatch 2 even launched in 2023. In late 2024, they started shipping the new lighting system.

Working on a new, more fancy tile set for more fancy tree structures.. #gamedev

So I'm rendering stuff in the following order:

1. Background image
2. Background fluid color, opaque
3. Sprites etc
4. Foreground fluid color, transparent

So where there's fluid, you should not see the background image, right

SO WHY DO I SEE A BACKGROUND IMAGE

Worse, if I remove the call to draw the foreground fluid, OR make the foreground fluid transparent, IT BEHAVES AS I EXPECT AND THE BACKGROUND IMAGE GOES AWAY

What the actual fuck

I've been having some thoughts about my game's windowing library. I use #glfw and am mostly happy with its API. But I'm not sure I wanna keep using it. I have weird stacking order and focus bugs on macOS, and window resizing is SUPER laggy on #GNOME #Wayland. Those are really the only two platforms I use.

I used to use #SDL to create windows. I moved to GLFW because SDL is overkill, but maybe I should go back.. if I can't find a way to make GLFW less broken that is #linux#gamedev #programming
