BROKEN: Big refactoring happening, so it compiles but game does not run and the tests fail. 		2 years ago
amt The tracy directory now has an experiment in getting Tracy to work. It's _not_ as easy as it is touted to be. 2 years ago
assets BROKEN: Big refactoring happening, so it compiles but game does not run and the tests fail. 2 years ago
magick Some quick hacks that do the seamless texture splits. 2 years ago
scratchpad Now the sprites are rendered in the 3d scene with just SFML sprites. 2 years ago
scripts Tweaking the build to turn on various debug options in GCC and enable -Wall -Werror on only our executable configs because turning them on globally causes most of the dependencies to fail. One thing to note is if you try to move the -D_GLIBCXX options from the project() to the executable() then you get segfaults inside the libc++ and other places. This is because the ABI changes when you enable these options, so you have to recompile _all_ dependencies with these options. 2 years ago
shaders Sprites now have a distance lighting calculation that's the same as the raycaster using a shader. 2 years ago
tests BROKEN: Big refactoring happening, so it compiles but game does not run and the tests fail. 2 years ago
tracy The tracy directory now has an experiment in getting Tracy to work. It's _not_ as easy as it is touted to be. 2 years ago
wraps We now have a full map that's basically the same mapping system from Roguish. There's a bug right now where it needs you to move once to calc the light and it's not being centered, but it does work. 2 years ago

camera.cpp FINALLY fix that stupid bug. The cause was two-fold: I was giving every 'enemy' a sprite, but that automatically included the player in the list of enemies, which meant that I was rendering the player's sprite while moving. Then in the sprite casting loop I was rendering things at 0. 2 years ago

Simple Raycaster Study

This is a study project for me to learn the raycasting technique. It's an older technique that's not really used much but I'm learning game dev historically and it's definitely been used in the past (Doom).

Don't Study This Code

This code is mostly a tech study and demo, not an actual game. It could be a game but it will require a significant cleanup to improve the layout and design. It's also the culmination of studying about 6 different tutorials on raycasting so it has a weird mix-match code style as I brought ideas over from other tutorials.

Eventually this will be more understandable, but for now just browse it casually and ignore the inconsistent style and kind of stupid structure.
