Function Documentation

ChangeSoundSet()

void ChangeSoundSet

(

int

index

)

Change the configured sound set and reset sounds.

Parameters

index

Index of sound set to switch to.

InitializeSound()

void InitializeSound

(

)

Definition at line 90 of file sound.cpp.

OpenBankFile()

static void OpenBankFile ( const std::string &  filename )

static

The sound file for the original sounds, i.e. those not defined/overridden by a NewGRF. Needs to be kept alive during the game as _original_sounds[n].file refers to this.

Definition at line 27 of file sound.cpp.

SetBankSource()

static bool SetBankSource ( MixerChannel *  mc, SoundEntry *  sound, SoundID  sound_id  )

SndCopyToPool()

void SndCopyToPool

(

Definition at line 153 of file sound.cpp.

SndPlayFx()

void SndPlayFx

(

SoundID

sound

)

Definition at line 245 of file sound.cpp.

SndPlayScreenCoordFx()

static void SndPlayScreenCoordFx ( SoundID  sound, int  left, int  right, int  top, int  bottom  )

static

Decide 'where' (between left and right speaker) to play the sound effect.

Note: Callers must determine if sound effects are enabled. This plays a sound regardless of the setting.

Parameters

sound	Sound effect to play
left	Left edge of virtual coordinates where the sound is produced
right	Right edge of virtual coordinates where the sound is produced
top	Top edge of virtual coordinates where the sound is produced
bottom	Bottom edge of virtual coordinates where the sound is produced
