Detailed Description

SCUMM implementation of IMuse. This class implements the IMuse mixin interface for the SCUMM environment.

Member Function Documentation

◆ setMusicVolume()

void Scumm::IMuseInternal::setMusicVolume ( int vol )

overridevirtual

Set the output volume for music. Also used, if the inheriting class doesn't distinguish between music and sfx.

Parameters

vol	the new output volume

Implements Scumm::MusicEngine.

◆ startSound()

void Scumm::IMuseInternal::startSound ( int sound )

overridevirtual

Start playing the sound with the given id.

Parameters

sound the sound to start

Implements Scumm::MusicEngine.

◆ stopSound()

void Scumm::IMuseInternal::stopSound ( int sound )

overridevirtual

Stop playing the sound with the given id.

Parameters

sound the sound to stop

Implements Scumm::MusicEngine.

◆ stopAllSounds()

void Scumm::IMuseInternal::stopAllSounds ( )

overridevirtual

Start playing all currently playing sounds.

Implements Scumm::MusicEngine.

◆ getSoundStatus()

int Scumm::IMuseInternal::getSoundStatus ( int sound ) const

overridevirtual

Query the status of the sound with the given id. Usually this is just a boolean telling us whether the sound is playing or not.

Parameters

sound the sound to for which we want the status

Returns: the status of the specified sound

Implements Scumm::MusicEngine.

◆ getMusicTimer()

int Scumm::IMuseInternal::getMusicTimer ( )

overridevirtual

Get the value of the music timer. Used for synchronising scripts with the music/sound.

Returns: the music timer

Reimplemented from Scumm::MusicEngine.
