github Latest version Documentation MIT Apache

Editable lookup curve for Bevy that can be used for many things, for example:

  • Animation
  • Gameplay progressiom (control different aspects over time or other variables)
  • Physics (for example: tweakable feel on a character controller)
  • Probability control (for item drops etc)
  • Shaders
  • ... just about anything where you need a formula (x -> y) that you can fine tune, with a GUI instead of diving into math

If you have used AnimationCurve in Unity, this would be an attempt at something similar for Bevy.

Features

  • LookupCurve type with modifiable knots and tangents. Three types of interpolation: Constant, Linear, and Cubic
  • LookupCurve implements bevy_math::Curve<f32> to fit into the ecosystem, giving access to resampling and other conveniences.
  • Asset loader and save functionality
  • egui-based editor
  • Integration with bevy-inspector-egui for quick and easy tweaking

Using without Bevy

This crate can be used without Bevy as well (except for bevy_math which is a core dependency).

Just set default-features = false. And enable serialize, ron, and/or editor_egui if needed.

See the egui_only example. It can also be used as a standalone curve editor.
