Other Syntax and Information

GUI Condition

This condition is whether the specified players have or don't have a GUI open. Patterns:

%players% (has|have) a gui [open]
%players% (doesn't|does not|do not|don't) have a gui [open]

If you see this in patterns, it simply means the syntax wants a GUI.

Technical Note: The only reason it's called a "guiinventory" is because Skript does not like the name "gui"
