Froggy is a prototype for Component Graph System. Froggy is not an ECS (it could as well be named "finecs" but then it would have "ecs" in the name... yikes)! Give it a try if:

  • you are open to new paradigms and programming models
  • you are tired of being forced to think in terms of ECS
  • you like simple composable things

Check ecs_bench for performance comparisons with actual ECS systems.


extern crate froggy;

fn main() {
    let mut positions = froggy::Storage::new();
    // create entities
    let entities = vec![
        positions.create(1u8), positions.create(4u8), positions.create(9u8)
    // update positions
    for e in &entities {
        positions[e] += 1;
