Shape#

struct nvShape#

Collision shape.

Public Members

nvShapeType type#

Type of the shape

nv_float radius#

Circle radius.

nvArray *vertices#

Polygon local vertices.

nvArray *trans_vertices#

Polygon transformed vertices.

nvArray *normals#

Polygon edge normals.

Enums#

enum nvShapeType#

Shape type enumerator.

Values:

enumerator nvShapeType_CIRCLE#

Circle shape. It’s the simplest collision shape.

enumerator nvShapeType_POLYGON#

Convex polygon shape. It’s more complex than circle shape and the calculations gets more expensive as the vertex count goes higher.
