Collider

Collider changes simple authored box and sphere Colliders at runtime. Use Collider.ShapeBox and Collider.ShapeSphere; unsupported shapes are rejected.

Method	Returns	Description
`Collider.Has(gameObjectId)`	boolean	Checks for a Collider.
`Collider.GetShape(gameObjectId)`	integer or `nil`	Reads the shape constant.
`Collider.SetShape(gameObjectId, shape)`	boolean	Changes the shape.
`Collider.IsTrigger(gameObjectId)`	boolean	Reads trigger state.
`Collider.SetIsTrigger(gameObjectId, isTrigger)`	boolean	Changes blocking/trigger behavior.
`Collider.GetSize(gameObjectId)`	Vec3 or `nil`	Reads box size.
`Collider.SetSize(gameObjectId, x, y, z)`	boolean	Sets positive box dimensions.
`Collider.GetRadius(gameObjectId)`	number or `nil`	Reads sphere radius.
`Collider.SetRadius(gameObjectId, radius)`	boolean	Sets a positive sphere radius.

doorGameObjectId = -1

function OpenDoor(gameObjectId)
  if Collider.Has(doorGameObjectId) then
    Collider.SetIsTrigger(doorGameObjectId, true)
  end
  GameObject.SetActive(doorGameObjectId, false)
end

Changing a Collider can change collision pairs on the following simulation step. Use trigger callbacks for overlap-only volumes and collision callbacks for blocking contacts.
