Benimator

A sprite animation library for rust game development.

Initially designed for bevy, it is now engine agnostic.

Status

This project is discontinued.

Goals

This project aim to provide the building the blocks to facilitate 2d sprite animation with any game engine.

Non-goals

Benimator is not rendering anything. It only keeps track of sprite indices.

One is expected to use benimator with a game engine such as bevy.

How it looks like

At its core benimator is an Animation data structure and a State to track the frame-index as time pass.

// Create an animation
let animation = Animation::from_indices(0..=3, FrameRate::from_fps(10.0));

// Create a new animation state
let mut state = State::new();

// In the game loop, for each update, tell the state how much time has elapsed
let delta_time = Duration::from_millis(250);
state.update(&animation, delta_time);

// Then get the current frame index.
// (so that we can tell our engine to render the sprite at that index)
assert_eq!(state.frame_index(), 2);

Have a look at the examples for complete examples using the bevy game engine.
