Class Segment

Definition

Namespace:
Tizen.NUI.Physics2D.Chipmunk
Assembly:
Tizen.NUI.Physics2D.dll

A line segment shape between two points, which is mainly useful when it behaves statically, though it can be beveled to give it thickness.

Segment(Body, Vect, Vect, double)

Create a line segment.

Declaration
public Segment(Body body, Vect a, Vect b, double radius)
Parameters
Type Name Description
Body body

The body to attach the segment to.
Vect a

The first endpoint of the segment.
Vect b

The second endpoint of the segment.
double radius

The thickness of the segment.

Properties

A

Get the first endpoint of the segment shape.

Declaration
public Vect A { get; }
Property Value
Type Description
Vect

Area

Calculate the area of the segment, assuming a thickness has been provided. The area is calculated assuming the endpoints would be rounded, like a capsule.

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

B

Get the second endpoint of the segment shape.

Declaration
public Vect B { get; }
Property Value
Type Description
Vect

Normal

Get the normal of the segment shape.

Declaration
public Vect Normal { get; }
Property Value
Type Description
Vect

Radius

Get the segment radius.

Declaration
public double Radius { get; }
Property Value
Type Description
double

SetNeighbors(Vect, Vect)

Let Chipmunk know about the geometry of adjacent segments to avoid colliding with endcaps.

Declaration
public void SetNeighbors(Vect prev, Vect next)
Parameters
Type Name Description
Vect prev
Vect next
