public Chars PROPERTY_UPDATE

Get World global viscosity/drag.
to simulate air friction.
return drag [0-1]

double getDrag ()

Set World global viscosity/drag.
param drag [0-1]

void setDrag (double d)

Get integrator used to update the physique world.
return Integrator

Integrator getIntegrator ()

Set integrator used to update the physique world.
param solver

void setIntegrator (Integrator integrator)

Contain object holding all collisions and managing events.
return CollisionsState

CollisionsState getCollisionsState ()

List the world singularities.
The list is a view, use addSingularity/removeSingularity methods to modify it.
return Sequence, never null, can be empty.

Sequence getSingularities ()

Add singularity in this world.
param singularity

void addSingularity (Singularity singularity)

Remove singularity from this world.
param singularity

void removeSingularity (Singularity singularity)

List the world bodies.
The list is a view, use addBody/removeBody methods to modify it.
return Sequence, never null, can be empty.

Sequence getBodies ()

Add body in this world.
param body

void addBody (Body body)

Remove body from this world.
param body

void removeBody (Body body)

List the present forces.
The list is a view, use addForce/removeForce methods to modify it.
return Sequence, never null, can be empty.

Sequence getForces ()

Add force in this world.
param force

void addForce (Force force)

Remove force from this world.
param force

void removeForce (Force force)

Remove all elements in this world.

void removeAll ()

List the world bodies group.
Groups are used to define collision exclusions.
Bodies is the same group are not tested for collision.
return Sequence, never null, can be empty.

Sequence getGroups ()

Integration time step, used by solver.
return double in seconds

double getIntegrationTimeStep ()

Update the world using current solver.
param timeellapsed in seconds

void update (double timeellapsed)
