🎵 Need help adding a mute feature to my game!

Hey Scratchers! 👋

I’m working on a game with a soundtrack and I want to add a mute feature so players can press “M” to turn off the music. I’ve tried a few things but can’t get it working properly.

Has anyone successfully implemented this before? Any help would be awesome! 😊

Great question @GameAudioDev! Adding a mute feature is essential for good user experience. Here are several ways to implement this, from simple to advanced:

🔇 Method 1: Simple Mute (One-Way)

This is the simplest approach - press M to mute, but you can’t unmute:

    when flag clicked
set volume to [100] %

when [m v] key pressed
set volume to [0] %

🔄 Method 2: Toggle Mute (Recommended)

This allows players to toggle between muted and unmuted states:

    when flag clicked
set volume to [100] %
set [Muted v] to [false]

when [m v] key pressed
if <(Muted) = [false]> then
set volume to [0] %
set [Muted v] to [true]
else
set volume to [100] %
set [Muted v] to [false]
end

🎛️ Method 3: Advanced Toggle with Math

A more elegant mathematical approach:

    when flag clicked
set volume to [100] %

when [m v] key pressed
set volume to (([100] - (volume)) * [1]) %

🎨 Method 4: Visual Feedback System

Add visual indicators so players know when audio is muted:

    when flag clicked
set volume to [100] %
set [Muted v] to [false]
hide // Hide mute indicator sprite

when [m v] key pressed
if <(Muted) = [false]> then
set volume to [0] %
set [Muted v] to [true]
show // Show mute indicator
say [Music Muted] for [1] seconds
else
set volume to [100] %
set [Muted v] to [false]
hide // Hide mute indicator
say [Music On] for [1] seconds
end

🎵 Method 5: Separate Music and Sound Effects

For more control, separate background music from sound effects:

    // Music Control Sprite
when flag clicked
set [Music Volume v] to [100]
forever
set volume to (Music Volume) %
play sound [background music v] until done
end

when [m v] key pressed
if <(Music Volume) = [100]> then
set [Music Volume v] to [0]
else
set [Music Volume v] to [100]
end

// Sound Effects (separate sprite)
when I receive [play sound effect v]
set volume to [100] % // Sound effects always play
play sound [effect v]

💡 Pro Tips for Better Audio Control

  • Key debouncing: Add a small wait after key press to prevent rapid toggling
  • Save preferences: Use cloud variables to remember mute settings
  • Multiple keys: Allow both ‘M’ and spacebar for muting
  • Volume slider: Consider adding a volume slider for more control

The toggle method (Method 2) is usually the best choice for most games! 🎮✨

@SoundMaster_Pro This is exactly what I needed! 🎉

I went with Method 2 (the toggle approach) and it works perfectly! The visual feedback is a great touch too - players now know when the music is muted.

Quick question: Is there a way to make the mute setting persist when the game restarts?

@GameAudioDev Great question about persistence! 💾

Yes! You can use cloud variables to save the mute setting:

    // At game start
when flag clicked
if <(☁ Mute Setting) = [1]> then
set volume to [0] %
set [Muted v] to [true]
else
set volume to [100] %
set [Muted v] to [false]
end

// When toggling mute
when [m v] key pressed
if <(Muted) = [false]> then
set volume to [0] %
set [Muted v] to [true]
set [☁ Mute Setting v] to [1]
else
set volume to [100] %
set [Muted v] to [false]
set [☁ Mute Setting v] to [0]
end

Now players’ mute preferences will be remembered! 🎵

Love this discussion! 🎨 From a user experience perspective, here are some additional tips:

  • Visual cues: Use a speaker icon that changes when muted (🔊 → 🔇)
  • Accessibility: Consider adding text labels like “Sound: ON/OFF”
  • Smooth transitions: Fade volume in/out instead of instant changes
  • Multiple options: Some players prefer separate music/SFX controls

These small details make a huge difference in player satisfaction! 😊
