Single header C library to turn your buffer into a generic doubly linked list, by sacrificing the first few elements. Provides some typesafety through the ML_Add() macro.

	// This lib turns an array into a linked list by sacrificing the first
	// few elements of the array

	#ifndef ML_TYPE
	// by default max numItems is 65535, redefine ML_TYPE if needed
	#define ML_TYPE unsigned short

zloedi / roguelike_FOV.c

Last active May 13, 2024 21:51

Efficient roguelike grid FOV / shadowcasting / line of sight in a single C function inspired by https://docs.microsoft.com/en-us/archive/blogs/ericlippert/shadowcasting-in-c-part-one

	// Copyright (c) 2021 Stoiko Todorov
	// This work is licensed under the terms of the MIT license.
	// For a copy, see https://opensource.org/licenses/MIT.

	// What this function does:
	// Rasterizes a single Field Of View octant on a grid, similar to the way
	// field of view / line of sight / shadowcasting is implemented in some
	// roguelikes.
	// Uses rays to define visible volumes instead of tracing lines from origin
	// to pixels.
