end
end)
db = false

Yes i do have a clickdectector in my union(part). Yes this is in the same script. Could have made a shortcut with local .. = .. but decided to not do that.

This is meant to make it so if the door is clicked alrdy it should be transparency = 1 after 1 second + cancollide = false and if transparency = 1 then when u click it should make the door go from transparency 1 to 0 so its fully visible + making it so u cant go through it, added debounce which doesnt work either, Im really confused.

Pls help.
