List of all members.

Public Member Functions

void SetAsBox (float32 hx, float32 hy)
 Build vertices to represent an axis-aligned box.
void SetAsBox (float32 hx, float32 hy, const b2Vec2 &center, float32 angle)
 Build vertices to represent an oriented box.

Public Attributes

b2Vec2 vertices [b2_maxPolygonVertices]
 The polygon vertices in local coordinates.
int32 vertexCount
 The number of polygon vertices.

Detailed Description

Convex polygon.

The vertices must be in CCW order for a right-handed coordinate system with the z-axis coming out of the screen.

Member Function Documentation

void b2PolygonDef::SetAsBox ( float32  hx,
