Member Function Documentation

CollisionNames()

std::vector<std::string> CollisionNames

(

)

const

Get a vector of all the collision names.

Returns

All the collision names used to trigger audio playback on contact.

FillBufferFromFile()

void FillBufferFromFile

(

const std::string &

_audioFile

)

Fill the OpenAL audio buffer with data from a sound file.

Parameters

[in]

_audioFile

Name and an audio file.

FillBufferFromPCM()

bool FillBufferFromPCM	(	uint8_t *	_pcmData,
		unsigned int	_dataCount,
		int	_sampleRate
	)

Fill the OpenAL audio buffer from PCM data.

Parameters

[in]	_pcmData	Pointer to the PCM audio data.
[in]	_dataCount	Size of the PCM data.
[in]	_sampleRate	Sample rate for the PCM data.

Returns

True on success.

HasCollisionName()

bool HasCollisionName

(

const std::string &

_name

)

const

Get whether the source has a collision name set.

Parameters

[in]

_name

Name of a collision to check for.

Returns

True if the collision name was found.

IsPlaying()

bool IsPlaying

(

)

Is the audio playing.

Load()

bool Load

(

OnContact()

bool OnContact

(

)

const

Return true if the audio source is played on contact with another object.

Contact is determine based on a set of collision objects.

Returns

True if audio is played on contact.
