Detailed Description

Represents a sound (called an 'event') in the Fmod sound system.

Provides functions to start, pause, stop a sound, set parameters, change volume, pitch etc.

Member Function Documentation

◆ DeserializeComponent()

void plFmodEventComponent::DeserializeComponent ( plWorldReader & inout_stream )

overridevirtual

Override this to load the current state of the component from the given stream.

The active state will be automatically serialized. The 'initialized' state is not serialized, all components will be initialized after creation, even if they were already in an initialized state when they were serialized.

Reimplemented from plFmodComponent.

◆ OnDeactivated()

void plFmodEventComponent::OnDeactivated ( )

overrideprotectedvirtual

This method is called when the component gets deactivated.

Upon destruction, a component that is active first gets deactivated. Therefore OnDeactivated() should be used for typical game code cleanup.

See also: OnActivated(), OnDeactivated(), Initialize(), Deinitialize(), OnSimulationStarted()

Reimplemented from plComponent.

◆ OnMsgSetFloatParameter()

void plFmodEventComponent::OnMsgSetFloatParameter ( plMsgSetFloatParameter & ref_msg )

Allows one to set event parameters through the generic plMsgSetFloatParameter message.

Requires event parameter lookup via a name, so this is less efficient than SetParameter().

◆ OnSimulationStarted()

void plFmodEventComponent::OnSimulationStarted ( )

overrideprotectedvirtual

This method is called once for active components, at the start of the next world update, but only when the world is simulated.

This is the one preferred method to setup typical game logic. In a pure game environment there is no practical difference between OnActivated() and OnSimulationStarted(), as OnSimulationStarted() will be called right after OnActivated().

However, when a scene is open inside the editor, there is an important difference: OnActivated() is called once the component was created. OnSimulationStarted() is only called once the game simulation is started inside the editor. As an example, if a component starts a sound in OnActivated(), that sound will play right after the scene has been loaded into the editor. If instead the sound gets started in OnSimulationStarted(), it will only play once the user starts the game mode inside the editor.

Additionally, OnSimulationStarted() is only ever executed once on a component, even if the plWorld pauses and resumes world simulation multiple times. Thus components that should only execute a thing exactly once, will work correctly. In contrast OnActivated() and OnDeactivated() will be executed every time the component's active state is toggled, which could re-execute the same behavior multiple times.

See also: OnActivated(), OnDeactivated(), Initialize(), Deinitialize(), OnSimulationStarted()

Reimplemented from plComponent.

◆ plFmodComponentIsAbstract()

virtual void plFmodEventComponent::plFmodComponentIsAbstract ( )

inlineoverrideprivatevirtual

Implements plFmodComponent.

◆ SerializeComponent()

void plFmodEventComponent::SerializeComponent ( plWorldWriter & inout_stream ) const

overridevirtual

Override this to save the current state of the component to the given stream.

Reimplemented from plFmodComponent.

◆ SetPitch()

void plFmodEventComponent::SetPitch ( float f )

Todo: Global pitch might better be a bus setting

◆ StartOneShot()

void plFmodEventComponent::StartOneShot ( )

Plays a completely new sound at the location of this component and with all its current properties.

Pitch, volume, position, direction and velocity are copied to the new sound instance. The new sound event then plays to the end and cannot be controlled through this component any further. If the referenced Fmod sound event is not a "one shot" event, this function is ignored. The event that is controlled through this component is unaffected by this.
