PlayTileSound()

void PlayTileSound	(	const GRFFile *	file,
		SoundID	sound_id,
		TileIndex	tile
	)

Play a NewGRF sound effect at the location of a specific tile.

Parameters

PlayVehicleSound()

bool PlayVehicleSound	(	const Vehicle *	v,
		VehicleSoundEvent	event,
		bool	force
	)

Checks whether a NewGRF wants to play a different vehicle sound effect.

Parameters

v	Vehicle to play sound effect for.
event	Trigger for the sound effect.
force	Should we play the sound effect even if vehicle sound effects are muted?

Returns

false if the default sound effect shall be played instead.
