I'm trying to get a sound to loop back to a certain point, but first, I need to actually :Pause()!
This script simply starts it from the beginning after the wait:
script.Parent:Play()
wait(14.3)
script.Parent:Pause()
script.Parent.Volume = 0.5
wait(71.7)
script.Parent:Play()
Roblox and their bountiful sound and mesh freedoms... Help, please?
