Capsule2D

Introduction

A Capsule2D is a PositionedObject which can be used to perform collision tests. Since Capsule2Ds provide the same collision interface as other shapes, it is also considered a "shape". A Capsule2D is a shape that can be any length, but has rounded edges and a straight segment connecting the two points.

When are Capsules used?

Capsules are often used to determine if a collision has occurred between a moving Circle and another object. Since capsules use rounded edges, they can represent the area that a Circle occupies during and between two subsequent frames.

Capsule Size

Capsule size is controlled by two variables:

• Scale

• EndpointRadius

The following diagram shows hwo these values are used in a Capsule2D:
