is there a way to set up an no-pk protection?

hello.
one more time i need help hehe.
i want to know if there is a way to set up an protection that dont let players atack others... just mobs in the map... like the protection in the market...
if there is a way pls help me...

well
if i am not wrong
you need to check the map of cronus and market

you see there some numbers of pkX and pkY
fill in the right cordinates and it will make it pk free

not sure of that numbers but to be sure , check market map id and see where there are numbers differend and missing

then fill that number (other cordinates then ) in to the map you like to have private

to make a pk free map , please note that it works in a Square
so if you put X1 and Y 1 then it will make xy and yx 1 pk free

market is probaly something as 100Y and 500X

thats all i can say , because i cant check it at this moment
