Tomik18 These are really scripting questions. But to answer them quickly, background
music can be switched with the command "musicoverride=x" For no music/sound and give it a "blank" sound file
to play. For a door with no sound just remove the sound files from the doors "property settings"
And to remove "footfall" sound, try these...
Add to an entities .fpe file.
For the player use a trigger script
plrfootfall=x (1 on, 0=off)
I haven't used these in awhile, so let me know if they still work
My games never have bugs. They just develop random features..
Lots and lots of random features...
