IsEnabled()

Whether the virtual loop system is enabled or not

Public function Static

bool

 

ShouldListenerMoveForceUpdate

(
    const FTransform& LastTransform,
    const FTransform& CurrentTransform
)

Check to see if listener move is far enough such that a check for virtual loop realization is necessary

Public function

bool

 

Update

(
    float DeltaTime,
    bool bForceUpdate
)

Updates the loop and checks if ready to play (or 'realize').

Public function

void

 

UpdateFocusData

(
    float DeltaTime
)

Takes aggregate update delta and updates focus so that realization check can test if ready to play.

Public function Static

bool

 

Virtualize

(
    const FActiveSound& InActiveSound,
    bool bDoRangeCheck,
    FAudioVirtualLoop& OutVirtualLoop
)

Checks if provided active sound is available to be virtualized.
