Shape(IntPtr)

Create a Shape with the given shapeHandle.

Declaration
protected Shape(System.IntPtr shapeHandle)
Parameters
Type Name Description
System.IntPtr shapeHandle

The native shape handle.

Properties

View Source

Area

Get the calculated area of the shape.

Declaration
public double Area { get; }
Property Value
Type Description
double
View Source

Body

The body that this shape is associated with.

Declaration
public Body Body { get; set; }
Property Value
Type Description
Body
View Source

BoundingBox

Get the bounding box that contains the shape, given it's current position and angle.

Declaration
public BoundingBox BoundingBox { get; }
Property Value
Type Description
BoundingBox
View Source

CenterOfGravity

Get the center of gravity of the shape.

Declaration
public Vect CenterOfGravity { get; }
Property Value
Type Description
Vect
View Source

CollisionType

An arbitrary value representing the collision type of this shape. Only shapes with like collision types will collide.

Declaration
public int CollisionType { get; set; }
Property Value
Type Description
int
View Source

Data

Arbitrary user data.

Declaration
public object Data { get; set; }
Property Value
Type Description
object
View Source

Density

Density of the shape if you are having Chipmunk calculate mass properties for you.

Declaration
public double Density { get; set; }
Property Value
Type Description
double
View Source

Elasticity

The elasticity of the shape. A value of 0.0 is perfectly inelastic (no bounce). A value of 1.0 is perfectly elastic. Due to simulation inaccuracy, values of 1.0 or greater are not recommended.

Declaration
public double Elasticity { get; set; }
Property Value
Type Description
double
View Source

Filter

An arbitrary value representing the collision type of this shape. Only shapes with like collision types will collide.

Declaration
public ShapeFilter Filter { get; set; }
Property Value
Type Description
ShapeFilter
View Source

Friction

The friction coefficient, following the Coulomb friction model. A value of 0.0 is frictionless. https://en.wikipedia.org/wiki/Friction#Coefficient_of_friction

Declaration
public double Friction { get; set; }
Property Value
Type Description
double
View Source

Handle

The native handle.

Declaration
public System.IntPtr Handle { get; }
Property Value
Type Description
System.IntPtr
View Source

Mass

Mass of the shape to have Chipmunk calculate mass properties for you.

Declaration
public double Mass { get; set; }
Property Value
Type Description
double
View Source

Moment

Get the calculated moment of inertia for the shape.

Declaration
public double Moment { get; }
Property Value
Type Description
double
View Source

Sensor

Whether the shape is a sensor.

Declaration
public bool Sensor { get; set; }
Property Value
Type Description
bool
View Source

Space

Gets the space that this shape is registered within.

Declaration
public Space Space { get; }
Property Value
Type Description
Space
View Source

SurfaceVelocity

The surface velocity of the object. Useful for creating conveyor belts or players that move around. This value is only used when calculating friction, not resolving the collision.

Declaration
public Vect SurfaceVelocity { get; set; }
Property Value
Type Description
Vect
