bump again! someone here?

why'd you even need those ? they seem so useless.......

all i can see tho is that the first one would be used like this:

local something(cid)
    doCreatureSay(cid, "Hehe", 1)
end

doActionForAllPlayers(something)

that would make all players online say "Hehe"

not are useless at all! thanks for the example, can give some examples of area functions?
