public class b2Sweep
extends Pointer

This describes the motion of a body/shape for TOI computation. Shapes are defined with respect to the body origin, which may no coincide with the center of mass. However, to support dynamics we must interpolate the center of mass position.

Constructor Detail

b2Sweep

public b2Sweep()

Default native constructor.

b2Sweep

public b2Sweep(long size)

Native array allocator. Access with Pointer.position(long).

b2Sweep

public b2Sweep(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

position

public b2Sweep position(long position)

Overrides:

position in class Pointer

GetTransform

public void GetTransform(b2Transform xfb,
                         @Cast(value="float32")
                         float beta)

Get the interpolated transform at a specific time.

Parameters:

beta - is a factor in [0,1], where 0 indicates alpha0.

Advance

public void Advance(@Cast(value="float32")
                    float alpha)
