Parameters:

  • (Float)

Returns:

  • (Float)

def pan=(value)
  @pan = value
end

#speed=(value) ⇒ Float (writeonly)

Sets the playback speed. A value of 2.0 will play the sample at 200% speed and one octave higher. A value of 0.5 will play the sample at 50% speed and one octave lower. The valid range of this property depends on the operating system, but values up to 8.0 should work.

Parameters:

  • (Float)

Returns:

  • (Float)

Instance Method Details

#pausevoid

# File 'rdoc/gosu.rb', line 631

def pause; end

#paused?true, false

Returns whether the sample is paused.

Returns:

  • (true, false)

    whether the sample is paused.


641
# File 'rdoc/gosu.rb', line 641

def paused?; end

#playing?true, false

Returns whether the sample is playing.

Returns:

  • (true, false)

    whether the sample is playing.

# File 'rdoc/gosu.rb', line 645

def playing?; end

#resumevoid

This method returns an undefined value.

Resumes playback of the sample.


637
# File 'rdoc/gosu.rb', line 637

def resume; end

#stopvoid

This method returns an undefined value.

Stops playback of this sample instance. After calling this method, the sample instance is useless and can be discarded.
