public sealed struct Sandbox.Collision

There are various interfaces that can be given to components for specific purposes.

The HammerMesh component is added automatically to game objects in Hammer that are tied to a mesh.

The scene system includes a programmable particle system, which can be controlled completely with components.

S&box includes a full 3D and 2D physics system powered by the Source 2 engine, with great performance and stability. Rigidbodies, colliders, joints, raycasting, and trigger volumes are all usable through Components on GameObjects.

As you play with developing in s&box, you will notice some things are weird, missing, or suck. We are aware.

Scenes can be traced against using Scene.Trace - which uses a builder pattern to make construction a bit easier. At a minimum, traces have a shape, start, and end. You can also filter which specific tags will be hit or ignored, or opt-in to using your project's collision rule matrix by calling WithCollisionRules(tag).
