Bevy 2D physics

When to use

Load this when a Bevy app needs simulated 2D bodies, triggers, or layer filtering before choosing a solver. Pair with bevy-character-movement for player motion that should not be a rigid body. Pair with bevy-spatial-queries for casts that also wait on a solver.

ECS shape

• Components own velocity, mass, a circle radius, and a layer mask for props you simulate yourself.
• Resources own gravity.
• Systems integrate on FixedUpdate, then separate overlapping circles. .chain() runs separation after the step.
• Schedule: the fixed step is the clock. A solver plugin can replace the integrator when you need joints and a spatial index. This file does not name that plugin's types. Player locomotion stays on bevy-character-movement.
