exactly i have try it to make the same as home bhut whit places :p that is a scrip of tmn first when i got the mesage unknown comand and than i have chane som things an now th script wil start bhut when i type in chat /set place than i got no message enter happens nothing

okay so sometimes I try. good for the brains.
it has never really worked, I changed everything and the database as well.
if I put everything back to normal sample, PlacePos_y PlacePos_z ..... etc back to HomePos_y HomePos_z ... etc and put the old database back everything works fine but people on my server sex but then served a home point. kite and I make something that other people platsen could make themselves as their home

i hope you have enough greetz Jjustmee22
