Public Attributes

b2Vec2 m_vertex1
 These are the edge vertices.
b2Vec2 m_vertex2
b2Vec2 m_vertex0
 Optional adjacent vertices. These are used for smooth collision.
b2Vec2 m_vertex3
bool m_hasVertex0
bool m_hasVertex3

Detailed Description

A line segment (edge) shape. These can be connected in chains or loops to other edge shapes. The connectivity information is used to ensure correct contact normals.
