Zed A. Shaw 3986e6978e Sprites now have a distance lighting calculation that's the same as the raycaster using a shader.

amt The tracy directory now has an experiment in getting Tracy to work. It's _not_ as easy as it is touted to be. 2025-01-19 12:58:05 -05:00

magick Some quick hacks that do the seamless texture splits. 2025-01-22 11:14:57 -05:00
scratchpad Now the sprites are rendered in the 3d scene with just SFML sprites. 2025-01-23 11:24:06 -05:00
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. 2025-01-19 04:02:42 -05:00
shaders Sprites now have a distance lighting calculation that's the same as the raycaster using a shader. 2025-02-07 13:50:50 -05:00
tests More cleanup of the raycaster, finally removed the window as a dependency but I went against making it an sf::Drawable since that had a lot of code quality problems. 2025-02-04 22:52:04 -05:00

animator.cpp Tiles now record their textures and this is loaded from the map then converted to an indexed integer on the fly. 2025-01-31 13:37:01 -05:00
animator.hpp Implement a little junk camera on its own that we can use later for movement and views. 2025-02-03 11:08:17 -05:00
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. 2025-02-07 11:05:15 -05:00

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.
