Accessors

  • get shape(): Shape
  • The shape of this collider.

    Returns Shape

Methods

  • The events active for this collider.

    Returns ActiveEvents

  • Get the physics hooks active for this collider.

    Returns ActiveHooks

  • Find the closest intersection between a ray and this collider.

    This also computes the normal at the hit point.

    Returns

    The time-of-impact between this collider and the ray, or -1 if there is no intersection.

    Parameters

    • ray: Ray

      The ray to cast.

    • maxToi: number

      The maximum time-of-impact that can be reported by this cast. This effectively limits the length of the ray to ray.dir.norm() * maxToi.

    • solid: boolean

      If false then the ray will attempt to hit the boundary of a shape, even if its origin already lies inside of a shape. In other terms, true implies that all shapes are plain, whereas false implies that all shapes are hollow for this ray-cast.
