Constructor Details

PhysicsStepListenerContext

public PhysicsStepListenerContext(long contextVa)

Instantiate a context with the specified native object assigned but not owned.

For use in custom contact listeners.

Parameters:

contextVa - the virtual address of the native object to assign (not zero)

Method Details

getDeltaTime

public float getDeltaTime()

Return the duration of the current step. The context is unaffected. (native attribute: mDeltaTime)

Returns:

the duration (in seconds, >0)

getIsFirstStep

public boolean getIsFirstStep()

Test whether this is the first step. The context is unaffected. (native attribute: mIsFirstStep)

Returns:

true if it's the first step, otherwise false

getIsLastStep

public boolean getIsLastStep()

Test whether this is the last step. The context is unaffected. (native attribute: mIsLastStep)

Returns:

true if it's the last step, otherwise false

getPhysicsSystem

public PhysicsSystem getPhysicsSystem()

Access the system being simulated. The context is unaffected. (native attribute: mPhysicsSystem)

Returns:

the pre-existing object, or null if not found
