An open-source library for managing maps for roguelike games in Godot Engine. It helps with map generation, storing map data, and using pathfinding, raycasting, and FOV

FOV calculation using RPAS algorithm

Raycasting using Bresenham's lines

Pathfinding using Godot built-in A* class

Discovering cells that have been visible at least once

Chunk system loadind/freeing chunks, dumping and restoring chunk data

Draw and fill functions for drawing primitives (lines, ellipse, rects, circles, arcs)

Managing tiles in RGMap class

TileSet generator for Tilemaps based on data from RGMap

Merging maps. Placing one RGMap inside the other map

Entity tracking. Entities and their properties can also be considered while using FOV and pathfinding

Saving and loading data as a flat array
