Hahem - floodfilling should be working and the pathfinding is doing okay. There's some bugs near the edges (like if you go to the very top of the map) where some of the agents get stuck. It is working off of GDNative code, so it'll need to be compiled to libheatmap.dll/.so/.dylib in the win64/x11/osx folders under /assets/libraries/. At least, that's how I configured it for the the .gdnlib file.

Populates a grid that uses razcore's pathfinder class to build a heatmap - each tile referring to how far away they are from the goal. Uses a simple extra thread to keep the game from hitching up. Spawner creates some 500 heatmap following enemies that use as simple a set of nodes and code as possible to show off performance.
Currently, the enemies don't interact with the player - not sure how well it'd do with physics based collision detection with that many agents.
Note: I also built it using GDNative, but the performance gain was so minimal - just barely any faster using C++ for loops, since the biggest cost is actually in the calls to Astar.find_path(). It's a testament to how well GDScript can work.
