C# Class FarseerPhysics.Collision.Shapes.ChainShape

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.

Method Details

ChainShape() public méthode

Constructor for ChainShape. By default have 0 in density.

public ChainShape ( ) : System.Diagnostics
Résultat	System.Diagnostics

ChainShape() public méthode

Create a new chainshape from the vertices.

public ChainShape ( Vertices vertices, bool createLoop = false ) : System.Diagnostics
vertices	Vertices	The vertices to use. Must contain 2 or more vertices.
createLoop	bool	Set to true to create a closed loop. It connects the first vertice to the last, and automatically adjusts connectivity to create smooth collisions along the chain.
Résultat	System.Diagnostics

CompareTo() public méthode

Compare the chain to another chain

public CompareTo ( ChainShape shape ) : bool
shape	ChainShape	The other chain
Résultat	bool

clone() public méthode

public clone ( ) : Shape
Résultat	Shape

computeAABB() public méthode

public computeAABB ( AABB &aabb, Transform &transform, int childIndex ) : void
aabb	AABB
transform	Transform
childIndex	int
