ShapeBox
Physics Engine

Real-world physics, zero code

ShapeBox has a full rigid-body physics simulation built right in. Add gravity, collisions, joints, and forces — all through a visual panel, no scripting required.

Rigid body simulation

Give any mesh mass, friction, and restitution. Watch it tumble, bounce, and stack with physically accurate motion.

Automatic colliders

ShapeBox generates optimised collision shapes (box, sphere, capsule, convex hull) automatically from your mesh.

Joints & constraints

Hinge, ball-socket, prismatic — constrain objects to create doors, wheels, ropes, and mechanical linkages.

Trigger volumes

Define invisible trigger zones that fire events when a physics body enters or exits — ideal for game logic.

Forces & impulses

Apply directional forces, explosions, or wind fields from the visual scripting system or timeline.

GPU-accelerated

Physics runs on a dedicated WebAssembly worker so your frame rate stays smooth no matter how many bodies are in the scene.

Rigid Body Simulation

Physics that just works, visually

Give any mesh mass, friction, and restitution through a simple property panel. Watch objects tumble, bounce, and stack with physically accurate motion — all simulated in a dedicated WebAssembly worker so your frame rate never drops.

Collision shapes generated for you

ShapeBox analyses your mesh geometry and generates the most efficient collision shape automatically — box, sphere, capsule, or convex hull. You can override with a custom shape at any time, all without writing a single line of code.

Forces & Impulses

Wind, gravity, explosions — all visual

Apply directional gravity, area wind fields, point explosions, and per-object impulses from the visual scripting graph or directly from the timeline. Build interactive game mechanics and simulations without touching a physics API.
