So the problem is that you're printing ("Touching") or ("Touch Ended") for each touch, not connecting to the actual function. You're also not waiting between them and instantly setting the debounce to true/false.

To fix it:

1. Delete the lines that say print() and end).

2. Have a wait between setting debounce and have a check for the debounce.

Fixed script:

local part = script.Parent
local ceiling = workspace.ce
debounce = false
local waitTime1 = 3; -- Time to wait on the onTouched before resetting debounce.
local waitTime2 = 3; -- Time to wait on the TouchEnded function before resetting debounce.


function ontouched()
   if debounce then return end; -- If debounce is true, then stop here, else, continue.
    debounce = true
    ceiling.Transparency = 1
    wait(waitTime1);
    debounce = false
end

function touchedended()
   if debounce then return end; -- If debounce is true, then stop here. Else, continue.
    debounce = true
    ceiling.Transparency = 0
    wait(waitTime2); 
    debounce = false
end

script.Parent.Touched:Connect(function(ontouched);

script.Parent.TouchEnded:Connect(function(touchedended);
