AmbientSource Class
This class is used to create an ambient background sound that is non-directional.
Notice
For an ambient source to be played, a player is always required. In case an ambient source needs to be played when neither a world, nor the editor are loaded, a player should be created in the system script unigine.cpp; otherwise, no sound will be heard.
AmbientSource Class
Members
AmbientSource (string name, int stream = 0)
Constructor. Creates a new ambient sound source using a given sound file.Arguments
- string name - Path to the sound file.
- int stream = 0 - Positive value to create a streaming source, 0 to create a static source. If the flag is set, the sample will not be fully loaded into memory. Instead, its successive parts will be read one by one into a memory buffer.
float getGain ()
Returns volume of the sound.Return value
Volume. 0 means muted, 1 means maximum volume.float getLength ()
Returns the total length of the sound sample.Return value
Length of the sample in seconds.int getLoop ()
Returns a value indicating if the sample is looped.Return value
Positive number if the sample is looped; otherwise, 0.float getPitch ()
Returns a sound pitch.Return value
Factor, by which the current pitch will be multiplied.string getSampleName ()
Returns the name of the sound file.Return value
Path to the sound file.int getSourceMask ()
Returns a bit mask that determines to what sound channels the source belongs to. For a sound source to be heard, its mask should match at least with the player's sound mask in at least one bit.Return value
Integer, each bit of which specifies a sound channel.float getTime ()
Returns the current time, at which the sample is being played.Return value
Time in seconds.int isPlaying ()
Returns a value indicating if the sample is being played.Return value
1 if the sample is being played; otherwise, 0.int isStopped ()
Returns a value indicating if playback is stopped.Return value
1 if the sample is stopped; otherwise, 0.void play ()
Starts playing the sample.void setGain (float gain)
Sets volume of the sound.Arguments
- float gain - Volume. 0 means muted, 1 means maximum volume.
void setLoop (int mode)
Sets a value indicating if the sample should be looped.Arguments
- int mode - Positive number to loop the sample, 0 to play it only once.
void setPitch (float pitch)
Sets a sound pitch.Arguments
- float pitch - Factor, by which the current pitch will be multiplied.
void setSourceMask (int mask)
Updates a bit mask that determines to what sound channels the source belongs to. For a sound source to be heard, its mask should match with the player's sound mask in at least one bit.Arguments
- int mask - Integer, each bit of which specifies a sound channel.
void setTime (float time)
Sets time, from which the sample should be played.Arguments
- float time - Time in seconds.
void stop ()
Stops playback. This function saves the playback position so that playing of the file can be resumed from the same point.Last update: 03.07.2017
