Rust Bevy Fixed Step Physics

Use this skill to separate deterministic simulation from frame-rate-dependent presentation in Bevy games.

Core Workflow

1. Identify which movement must be deterministic and collision-safe.
2. Sample input in update systems, then apply movement in fixed-step systems.
3. Store velocity, acceleration, and intent explicitly in components/resources.
4. Predict or sweep movement before committing positions.
5. Emit physics/collision events; keep animation and particles as presentation.
6. Interpolate or tween visuals when fixed simulation looks choppy.
