Method Detail

debugDrawWorld

public void debugDrawWorld()

Specified by:

debugDrawWorld in class DynamicsWorld

clearForces

public void clearForces()

Specified by:

clearForces in class DynamicsWorld

applyGravity

public void applyGravity()

Apply gravity, call this once per timestep.

stepSimulation

public int stepSimulation(float timeStep,
                 int maxSubSteps,
                 float fixedTimeStep)

Description copied from class: DynamicsWorld

Proceeds the simulation over 'timeStep', units in preferably in seconds.

By default, Bullet will subdivide the timestep in constant substeps of each 'fixedTimeStep'.

In order to keep the simulation real-time, the maximum number of substeps can be clamped to 'maxSubSteps'.

You can disable subdividing the timestep/substepping by passing maxSubSteps=0 as second argument to stepSimulation, but in that case you have to keep the timeStep constant.

Specified by:

stepSimulation in class DynamicsWorld

setGravity

public void setGravity(Vector3f gravity)

Description copied from class: DynamicsWorld

Once a rigidbody is added to the dynamics world, it will get this gravity assigned. Existing rigidbodies in the world get gravity assigned too, during this method.
