Godot Volume Slider

A simple and ready-to-use volume slider plugin for Godot 4. It provides HVolumeSlider and VVolumeSlider nodes that directly control the volume of any audio bus.

Features

• Dynamic Bus Selection: Select the audio bus from a dropdown list in the Inspector, which is automatically populated with your project's actual audio buses.
• Horizontal & Vertical Slider :
  • HVolumeSlider
  • VVolumeSlider
• Automatic dB Conversion: Automatically converts the slider's linear value (by default 0-100) to the logarithmic dB scale used by Godot's AudioServer.
  • The conversion is based on the slider's range. The slider's max_value is mapped to full volume (0 dB), while its min_value is mapped to silence (-60db).
• Auto-Mute: Automatically mutes the bus when the volume is set to its minimum value.
• Volume Signal: Emits a volume_changed(volume_db) signal whenever the volume is adjusted.
