And if I want to mute more then 1 sound with a click do I use "SoundCollision""SoundPickup"? Or with + betwhen them or &, what?
The screen you posted isn't the right logic.
What the program will do is :
- Ev1 : on the Mute button clicked (any click, first or not) => mute the music, set the variable to 1
- after Ev1, if the variable is set to 1 (witch will be the case, since you just set it to 1), unmute the music and set the variable to 0.
Here is another implementation that should do it properly : example
You should use "onTouch" events from the touch object, since it will simulate an "onClick" too, but not the other way around. Though, on Buttons, it will work both ways.
If you want to mute multiple sounds with a single click, just mute them one after the other, where you muted/unmuted the background sound. If you want to mute all sounds, you can change the general volume too.
