public ChainShape()

Method Detail

getType

public Shape.Type getType()

Description copied from class: Shape

Get the type of this shape. You can use this to down cast to the concrete shape.

Specified by:

getType in class Shape

Returns:

the shape type.

createLoop

public void createLoop(float[] vertices)

Create a loop. This automatically adjusts connectivity.

Parameters:

vertices - an array of floats of alternating x, y coordinates.

createLoop

public void createLoop(float[] vertices,
                       int offset,
                       int length)

Create a loop. This automatically adjusts connectivity.

Parameters:

vertices - an array of floats of alternating x, y coordinates.

offset - into the vertices array

length - after offset (in floats, not float-pairs, so even number)

createLoop

public void createLoop(Vector2[] vertices)

Create a loop. This automatically adjusts connectivity.

Parameters:

vertices - an array of vertices, these are copied

createChain

public void createChain(float[] vertices)

Create a chain with isolated end vertices.

Parameters:

vertices - an array of floats of alternating x, y coordinates.

createChain

public void createChain(float[] vertices,
                        int offset,
                        int length)

Create a chain with isolated end vertices.

Parameters:

vertices - an array of floats of alternating x, y coordinates.

offset - into the vertices array

length - after offset (in floats, not float-pairs, so even number)

createChain

public void createChain(Vector2[] vertices)

Create a chain with isolated end vertices.

Parameters:

vertices - an array of vertices, these are copied

setPrevVertex

public void setPrevVertex(Vector2 prevVertex)

Establish connectivity to a vertex that precedes the first vertex. Don't call this for loops.

setPrevVertex

public void setPrevVertex(float prevVertexX,
                          float prevVertexY)

Establish connectivity to a vertex that precedes the first vertex. Don't call this for loops.

setNextVertex

public void setNextVertex(Vector2 nextVertex)

Establish connectivity to a vertex that follows the last vertex. Don't call this for loops.

setNextVertex

public void setNextVertex(float nextVertexX,
                          float nextVertexY)

Establish connectivity to a vertex that follows the last vertex. Don't call this for loops.

getVertexCount

public int getVertexCount()

Returns:

the number of vertices

getVertex

public void getVertex(int index,
                      Vector2 vertex)

Returns the vertex at the given position.

Parameters:

index - the index of the vertex 0 <= index < getVertexCount( )

vertex - vertex

isLooped

public boolean isLooped()
