## Detailed Description

This implements a solid consisting of a cylinder with hemispherical endcaps, also known as a capsule or a spherocylinder.

This shape was previously erroneously called CollisionTube.

## Member Function Documentation

## ◆ flush_level()

void CollisionCapsule::flush_level | ( |  | ) |
| inline static

## ◆ get_collision_origin()

LPoint3 CollisionCapsule::get_collision_origin | ( |  | ) | const
| virtual

Returns the point in space deemed to be the "origin" of the solid for collision purposes.

The closest intersection point to this origin point is considered to be the most significant.

## ◆ register_with_read_factory()

void CollisionCapsule::register_with_read_factory | ( |  | ) |
| static

Tells the BamReader how to create objects of type CollisionCapsule.

## ◆ write_datagram()

void CollisionCapsule::write_datagram | ( | BamWriter * | manager,
|  | Datagram & | dg
| ) |  |
| virtual

Writes the contents of this object to the datagram for shipping out to a Bam file.
