Constructor & Destructor Documentation

PhysicsShape

(

float

radius

)

Sphere Constructor.

Parameters:

radius

radius of sphere

PhysicsShape

(

Vector2

width

)

Box Constructor.

Parameters:

width

half width of box

width param is half width of box

PhysicsShape	(	Vector2[]	pos,
		int	num
	)

Convex Constructor.

Parameters:

pos	point list for convex shape
num	num of point list for convex shape

the limitation of number of point list containd by convex shape is 30

PhysicsShape	(	Vector2[]	pos,
		int	num,
		bool	flag
	)

Chain of Line Segments Constructor.

Parameters:

pos	point list for line shape
num	num of point list for convex shape
flag	true should be given

the limitation of number of point list containd by convex shape is 30, and this is only for static rigid body

PhysicsShape

(

PhysicsShape

con

)

PhysicsShape Copy Constructor.

Parameters:

con	shape of rigid body

Member Function Documentation

static PhysicsShape CreateConvexHull	(	Vector2[]	vertList,
		int	num
	)		[static]

create convex shape from random point

Parameters:

vertList	random point set
num	number of random point set

Returns:

convex shape

uint hint

hint for PhysicsShape

hint defines symmetry of PhysicsShape hint=1 means non symmetry, hint=2 means symmetry except for sphere and box, convex shape should define this property to accelarate the simulation when usr uses convex shape

Vector2 [] vertList = new Vector2[30]

list of points

assume maximum number of vertex = 30, numVert = 0 means sphere, this is the special case and the first x-coordinate of the point holds radius
