AmbientSource Class
This class is used to create a non-directional ambient background sound.
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
static 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 - 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.
void setGain(float gain)
Sets volume of the sound.Arguments
- float gain - Volume. 0 means muted, 1 means maximum volume.
float getGain()
Returns volume of the sound.Return value
Volume. 0 means muted, 1 means maximum volume.void * getInterface()
float getLength()
Returns the total length of the sound sample.Return value
Length of the sample in seconds.void setLoop(int loop)
Sets a value indicating if the sample should be looped.Arguments
- int loop - Positive number to loop the sample, 0 to play it only once.
int getLoop()
Returns a value indicating if the sample is looped.Return value
Positive number if the sample is looped; otherwise, 0.void setPitch(float pitch)
Sets a sound pitch.Arguments
- float pitch - Factor, by which the current pitch will be multiplied.
float getPitch()
Returns a sound pitch.Return value
Factor, by which the current pitch will be multiplied.int isPlaying()
Returns a value indicating if the sample is being played.Return value
1 if the sample is being played; otherwise, 0.void setSampleName(string name)
Reloads the internal sound source.Arguments
- string name - Path to the sound file.
string getSampleName()
Returns the name of the sound file.Return value
Path to the sound file.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.
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.int isStopped()
Returns a value indicating if playback is stopped.Return value
1 if the sample is stopped; otherwise, 0.void setTime(float time)
Sets time, from which the sample should be played.Arguments
- float time - Time in seconds.
float getTime()
Returns the current time, at which the sample is being played.Return value
Time in seconds.void play()
Starts playing the sample.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: 2017-07-03
