ChainShape Class

A chain shape is a free form sequence of line segments. The chain has two-sided collision, so you can use inside and outside collision. Therefore, you may use any winding order. Connectivity information is used to create smooth collisions. WARNING: The chain will not collide properly if there are self-intersections.

public class ChainShape : Shape

The ChainShape type exposes the following members.

Constructors
 NameDescription
Public methodChainShape Constructor for ChainShape. By default have 0 in density.
Public methodChainShape(Vertices, Boolean) Create a new chainshape from the vertices.

Properties
 NameDescription
Public propertyChildCount
(Overrides ShapeChildCount)
Public propertyDensity Gets or sets the density. Changing the density causes a recalculation of shape properties.
(Inherited from Shape)
Public propertyNextVertex Establish connectivity to a vertex that follows the last vertex. Don't call this for loops.
Public propertyPrevVertex Establish connectivity to a vertex that precedes the first vertex. Don't call this for loops.
Public propertyRadius Radius of the Shape Changing the radius causes a recalculation of shape properties.
(Inherited from Shape)
Public propertyShapeType Get the type of this shape.

Methods
 NameDescription
Public methodClone
(Overrides ShapeClone)
Public methodCompareTo Compare the chain to another chain
Public methodComputeAABB
(Overrides ShapeComputeAABB(AABB, Transform, Int32))
Protected methodComputeProperties
(Overrides ShapeComputeProperties)
Public methodComputeSubmergedArea
(Overrides ShapeComputeSubmergedArea(Vector2, Single, Transform, Vector2))
Public methodEqualsDetermines whether the specified object is equal to the current object.
(Inherited from Object)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object)
Public methodGetChildEdge Get a child edge.
Public methodGetHashCodeServes as the default hash function.
(Inherited from Object)
Public methodGetTypeGets the Type of the current instance.
(Inherited from Object)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
Public methodRayCast
(Overrides ShapeRayCast(RayCastOutput, RayCastInput, Transform, Int32))
Public methodTestPoint
(Overrides ShapeTestPoint(Transform, Vector2))
Public methodToStringReturns a string that represents the current object.
(Inherited from Object)

Fields
 NameDescription
Public fieldMassData Contains the properties of the shape such as: - Area of the shape - Centroid - Inertia - Mass
(Inherited from Shape)
Public fieldVertices The vertices. These are not owned/freed by the chain Shape.
