| − | === Event "engine" ===
| |
| − | | |
| − | Event "engine" plays sound of the engine.<br>
| |
| − | It has to be 3D event. The event should be routed to the "truck_engine" audio bus.<br>
| |
| − | The event must be looped and its living cycle is controlled by "play" parameter (see bellow).<br>
| |
| − | <br>
| |
| − | These event parameters must exist:
| |
| − | * engine/play<br>The parameter "play" control living cycle of the event:<br>value play = 1 means - sound is playing<br>value play = 0 means - sound should be stopped
| |
| − | * engine/brake<br>the value is in the range <0 - 1> and represents the action of the motor brake
| |
| − | * engine/load<br>the value is in the range <0 - 1><br>value represents the motor load<br>value < 0.05 means idle engine sound
| |
| − | * engine/rpm<br>the value is in the range <0 - 3000><br>the value represents the number of engine revs per second
| |
| − | | |
| − | === Event "exhaust" ===
| |
| − | | |
| − | Event "exhaust" plays sound of the exhaust.<br>
| |
| − | It has to be 3D event. The event should be routed to the "truck_exhaust" audio bus.<br>
| |
| − | The event must be looped and its living cycle is controlled by "play" parameter.<br>
| |
| − | <br>
| |
| − | These event parameters must exist:
| |
| − | * exhaust/load
| |
| − | * exhaust/play
| |
| − | * exhaust/rpm
| |
| − | The purpose of the parameters is the same as for the "engine" event (see Event "engine").
| |
| − | | |
| − | === Event "turbo" ===
| |
| − | | |
| − | Event "turbo" plays sound of the turbo.<br>
| |
| − | It has to be 3D event. The event should be routed to the "truck_turbo" audio bus.<br>
| |
| − | The event must be looped and its living cycle is controlled by "play" parameter.<br>
| |
| − | <br>
| |
| − | These event parameters must exist:
| |
| − | * engine/turbo<br>the value is in the range <0 - 1> and represents the action of the turbo system
| |
| − | | |
| − | === Event "start_bad" ===
| |
| − | Event "start_bad" plays sound of unsuccessful starting of the engine.<br>
| |
| − | It has to be 3D event. The event should be routed to the "truck_engine" audio bus.<br>
| |
| − | The event is one-shot sound (without loop).<br>
| |
| − | There are no other parameters for the event.<br>
| |
| − | It is possible to use randomization of the assets supported by FMOD Studio.<br>
| |
| − | | |
| − | == Engine Sound Configuration ==
| |
| − | | |
| − | The sound configuration of the engine sounds is stored in the "accessory_engine_data" data.<br>
| |
| − | There is array "sounds" which contents specification for the mandatory events of the engine.<br>
| |
| − | That means that each type of the engine can have assigned its own sound bank.<br>
| |
| − | <br>
| |
| − | Example:<br>
| |
| − | There are configuration files of engines for the "Peterbilt 579" at the folder "\def\vehicle\truck\peterbilt.579\engine".<br>
| |
| − | Each engine include ''@include "sound.sui" '' file which contents indirect definition of the events:
| |
| − | <pre>
| |
| − | sounds: 4
| |
| − | sounds[]: "engine|/def/vehicle/truck/peterbilt.579/engine/sound_engine.soundref"
| |
| − | sounds[]: "exhaust|/def/vehicle/truck/peterbilt.579/engine/sound_exhaust.soundref"
| |
| − | sounds[]: "start_bad|/def/vehicle/truck/peterbilt.579/engine/sound_start_bad.soundref"
| |
| − | sounds[]: "turbo|/def/vehicle/truck/peterbilt.579/engine/sound_turbo.soundref"
| |
| − | </pre>
| |
| − | There are .soundref file (for each event) to specify bank end FMOD event of the sound.
| |
| − | | |
| − | Content of the sound_engine.soundref is:
| |
| − | <pre>
| |
| − | source="/sound/truck/peterbilt_579.bank#engine/engine"
| |
| − | </pre>
| |
| − | | |
| − | The record<br>sound: ''"/sound/truck/peterbilt_579.bank"''<br>at the any engine configuration file assigns the sound bank to the engine.
| |
| − | | |
| − | == Engine Sound Position ==
| |
| − | | |
| − | The 3D position of the engine sound is (by default) 1 m above the first axle of the truck.<br>
| |
| − | This position could be modified by the .soundref file. (see [[Documentation/Engine/Sound#Sound_reference_file|Sound reference file]])
