# boids
|
|
|
|
addon for Godot that adds 2D / 3D boids (flocking).
|
|
|
|
|
|
|
|
it can handle about 2000 boids in a single flock at 11ms physics process tick on my PC (Ryzen 5600).
|
|
(keep in mind this is without any partitioning of sorts, so it's bound to get better)
|
|
|
|
## usage
|
|
|
|
download it from the [asset library](https://godotengine.org/asset-library/asset/3284).
|
|
|
|
or clone the repository, and run `just build-all` to build the libraries (in release mode) for all supported targets.
|
|
(requires [cross](https://github.com/cross-rs/cross), [just from `master` branch](https://github.com/casey/just) and [nushell](https://github.com/nushell/nushell))
|
|
|
|
## development
|
|
|
|
it's just a standard rust project under `rust`, so make sure you have the latest stable rust toolchain installed.
|
|
also don't forget to have godot installed and available in your `PATH` (the extension currently targets 4.3).
|
|
|
|
- **cargo features**
|
|
- enable `stats` feature to let the extension log into godot console some times for how its processing the boids.
|
|
|
|
## todo
|
|
|
|
- [ ] memoize calculated distances
|
|
- [ ] implement avoidance (point avoidance, edge avoidance)
|
|
- [ ] implement nodes for these (for 2d, point and a rect node and 3d point and a cube node, circle / sphere too)
|
|
- [ ] implement partitioning (quadtree/octree)
|
|
- [ ] do we just use `spatialtree` crate?
|
|
- [ ] write better usage documentation
