Ignore many events if case is met?

I am implementing levels in my game. When a stage marker is reached I want many events, for example keyboard controls and various animations to no longer work.

At the moment I am going though and putting extra conditions on all those events.

i.e., if not Player.EndofStageReached then Do_Keyboard etc

I was thinking is it perhaps possible to have

if not Player.EndofStageReached then

begin

all the events

in here

end;

For example is it possible to put a condition of a group?

Yes, Groups is what you want!

Yes, but what I can't figure out is how to exclude a whole group from being run.

Am I missing something obvious? It wouldn't be the first time ;)

System:(General):Set group active

That is awesome. Thanks that makes life easier. Still learning :)
