2D physics layout container turning UI elements into simulated rigid bodies with fixed-timestep JBox2D simulation, shapes, boundaries, pointer dragging modes, collision/drag/step events.
PhysicsBox is a Compose Multiplatform physics layout container for Android and Desktop (JVM). It turns composables into 2D physics bodies and renders their motion by applying translation and rotation during layout.
The runtime uses JBox2D on JVM platforms, giving you stable rigid-body simulation with fixed-timestep stepping, boundaries, dragging, and collision callbacks.
