Luafinding is an A* module written in Lua with the main purposes being ease of use & optimization.

To run a performance test yourself, see performance/performance.lua. Move all the Lua files in src/ to that folder and run performance.lua in your console. Here are my performance results:

> luajit performance.lua
Using seed 1614795006
Building 100 x 100 sized map.
Generating 2000 random start/finish positions.
Finding 1000 paths.
Done in 0.309 seconds.
Average of 0.000309 per path.

To compare, "lua-star" runs at an average of 0.0017 seconds per path on my machine for a 100x100 map; that's an 81.8% improvement from one of the mainstream Love2D pathfinding methods.

Not to mention that a lot of Love2D implementations also feature a lot of O(n) for tables instead of indexing. When testing "lua-star" in Love2D, it ran at about 2 seconds per path - whereas Luafinding, on my machine, runs at 0.00034 seconds per path. That's an entire 99.98% decrease in computing time.
