SHARED STATES AND SWITCHES

The WwiseSampleProject provides you with many State and Switch groups which you can use to integrate your audio in the game, and this page gives you all the details required to use them. Note that you can't create new Switch or State groups, as those are included in the Init Soundbanks of the WwiseSampleProject. If required, you can work around this by using SimVarSounds, Requirements Attributes, or even by creating your own game parameters.

 

 

Shared Viewpoint States

You can find the VIEWPOINT States group here:

\States\aircraft\VIEWPOINT

This state group will help you switching smoothly between you sounds on camera changes. We always recommend using it for engine sounds, so you can easily manage the engine sound transition between the inside and outside viewpoint:

 

You can also use it to mute outside or inside sounds in the Sound Property Editor:

 

 

Shared Surfaces Type Switches

You can find the surface type switch group here:

\Switches\surface\surfaces

This switches group allows to integrate sounds depending on the ground surface:

This switch group is using the SIMVAR_SURFACE_TYPE game parameter. It's implemented by default on GroundSounds triggers, but you can use it on any audio events (rattles, shakes, etc...). Just make sure to send the correct SURFACE TYPE SimVar on your sound through the sound.xml, for example:

<WwiseRTPC SimVar="SURFACE TYPE" Units="ENUM" Index="0" RTPCName="SIMVAR_SURFACE_TYPE" /> 

 

 

Shared Flight Control Switches

Flight control switches are hooked to SimVar through Wwise RTPC. If you want to use them, make sure to send the SimVar into Wwise RTPC using the sound.xml. As an example, here's some XML for the left aileron of an aircraft:

<Sound WwiseData="true" WwiseEvent="aileron_left" NodeName="AILERON_LEFT" ContinuousStopDelay="1.0" SimVar="AILERON POSITION" Units="PERCENT" Index="1">
      <WwiseRTPC SimVar="AILERON POSITION" Units="PERCENT" Index="1" RTPCName="SIMVAR_AILERON_POSITION" />
      <WwiseRTPC SimVar="AILERON POSITION" Units="PERCENT" Index="1" Derived="true" RTPCName="SIMVAR_AILERON_POSITION_DERIVED" />
  </Sound>

The table below lists the available switches:

 

Switch Group name	SIMVAR	RTPCName	Derived	Description
aileron_left_movement	AILERON POSITION	SIMVAR_AILERON_POSITION	No	This switch allows you to bind sounds on left aileron movements and stops. You should set up "Index=1" as a sound attribute in the sound.xml.
aileron_right_movement	AILERON POSITION	SIMVAR_AILERON_POSITION	No	This switch allows you to bind sounds on right aileron movements and stops. You should set up "Index=2" as the sound attribute in the sound.xml.
elevator_movement	ELEVATOR POSITION	SIMVAR_ELEVATOR_POSITION	No	This switch allows you to bind sounds on elevator movements and stops.
rudder_movement	RUDDER_POSITION	SIMVAR_RUDDER_POSITION	No	This switch allows you to bind sounds on rudder movements and stops.
flaps_left_move_generic	TRAILING_EDGE_FLAPS_LEFT_PERCENT	SIMVAR_TRAILING_EDGE_FLAPS_ LEFT_PERCENT_DERIVED	Yes	This switch allows you to bind sounds on left flaps movements and stops.
flaps_right_move_generic	TRAILING_EDGE_FLAPS_RIGHT_PERCENT	SIMVAR_TRAILING_EDGE_ FLAPS_RIGHT_PERCENT_DERIVED	Yes	This switch allows you to bind sounds on right flaps movements and stops.
flaps_left_up_down	TRAILING_EDGE_FLAPS_LEFT_PERCENT	SIMVAR_TRAILING_EDGE_ FLAPS_LEFT_PERCENT_DERIVED	Yes	This switch allows you to bind sounds on left flaps up or down movements.
flaps_right_up_down	TRAILING_EDGE_FLAPS_RIGHT_PERCENT	SIMVAR_TRAILING_EDGE_ FLAPS_RIGHT_PERCENT_DERIVED	Yes	This switch allows you to bind sounds on right flaps up or down movements.
canopy_movement	CANOPY OPEN	SIMVAR_CANOPY_OPEN_DERIVED	Yes	This switch allows you to bind sounds on canopy movements and stops.
exit_door_movements	EXIT OPEN	SIMVAR_EXIT_OPEN_DERIVED	Yes	This switch allows you to bind sounds on exit door movements and stops.
exit_door_direction	EXIT OPEN	SIMVAR_EXIT_OPEN_DERIVED	Yes	This switch allows you to bind sounds on exit door on opening or closing movements.
gears_movement	GEAR_TOTAL_PCT_EXTENDED	SIMVAR_GEAR_TOTAL_PCT_ EXTENDED_DERIVED	Yes	This switch allows you to bind sounds on exit door movements and stops.
gears_direction	GEAR_TOTAL_PCT_EXTENDED	SIMVAR_GEAR_TOTAL_PCT_ EXTENDED_DERIVED	Yes	This switch allows you to bind sounds on gears ups or down movements.
left_gears_movements	GEAR_LEFT_POSITION	SIMVAR_GEAR_LEFT_ POSITION_DERIVED	Yes	This switch allows you to bind sounds on left gear movements and stops.
left_gears_direction	GEAR_LEFT_POSITION	SIMVAR_GEAR_LEFT_ POSITION_DERIVED	Yes	This switch allows you to bind sounds on left gears ups or down movements.
right_gears_movements	GEAR_RIGHT_POSITION	SIMVAR_GEAR_RIGHT_ POSITION_DERIVED	Yes	This switch allows you to bind sounds on right gear movements and stops.
right_gears_direction	GEAR_RIGHT_POSITION	SIMVAR_GEAR_RIGHT_ POSITION_DERIVED	Yes	This switch allows you to bind sounds on right gears ups or down movements.
