public static class Distance.DistanceProxy

Object
Distance.DistanceProxy

A distance proxy is used by the GJK algorithm. It encapsulates any shape. TODO: see if we can just do assignments with m_vertices, instead of copying stuff over

Fields

`public final` `Vec2[] m_vertices`
`public int m_count`
`public float m_radius`
`public final` `Vec2[] m_buffer`

Constructors

public DistanceProxy()

Methods

`public final void set(Shape shape, int index)`	Initialize the proxy using the given shape.
`public final int getSupport(Vec2 d)`	Get the supporting vertex index in the given direction.
`public final` `Vec2 getSupportVertex(Vec2 d)`	Get the supporting vertex in the given direction.
`public final int getVertexCount()`	Get the vertex count.
`public final` `Vec2 getVertex(int index)`	Get a vertex by index.

Method details

set

public final void set(Shape shape, int index)

Initialize the proxy using the given shape. The shape must remain in scope while the proxy is in use.

getSupport

public final int getSupport(Vec2 d)

Get the supporting vertex index in the given direction.

getSupportVertex

public final Vec2 getSupportVertex(Vec2 d)

Get the supporting vertex in the given direction.

getVertexCount

public final int getVertexCount()

Get the vertex count.

getVertex

public final Vec2 getVertex(int index)

Get a vertex by index. Used by Distance.
