Continuous interaction presets
- Top-down Character — standing outward response plus movement force.
- Platformer Character — body response plus lateral movement force.
- Moving Object — velocity-driven deformation for props/vehicles.
- Swing — oscillating authored direction.
- Pulse — repeating radial strength envelope.
- Custom — directional/radial/vortex flow with optional Pulse Overlay.
Interaction shapes
Continuous interaction and optional one-shot actions share one authored footprint. Supported shapes are Circle, rotated Box, Ellipse, Capsule, Segment, Collider2D and Custom Polygon. Concave polygons are supported; custom polygons use up to 64 points.
- Circle/Box continuous interaction stays on the cheap transient-source path.
- Advanced shapes use the polygon-capable composition path.
- Falloff is a real spatial exponent and the Scene contours show the same mapping used at runtime.
One-shot actions
- Bend — directional temporary deformation.
- Pulse — radial temporary deformation.
- Cut — persistent shortened vegetation state.
- Destroy — persistent hidden/collapsed vegetation state.
- Grow — timed growth animation.
- Regrow — restores matching Cut/Destroy state and animates vegetation back in.
