did you added some mapflag like this somewhere in your other script ?
mapname mapflag nowarp
mapname mapflag nogo
mapname mapflag nocommand
etc....
if yes then remove it
well...good try..but it wont work..
like what cyledion has mentioned...they can re-equip...
and due to too many item to disable from the map.. and items...
without any src for creating a new mapflag....
i can suggest you to do it in this way...
create a simple npc warper..that check for Item Weight
if the player current Weight is larger than 0....he cant go in the map...
or
you can use getinventory command..
if the users have more than 1 items or 0 items..
he cant go into the map.
with this..i think they are not be able to bring any items into the map..
but of course...the idea might still have not good enough to fit what you want.
