But how? thats my question, because i dont know where put the coordinates, but i'm fixing it, just give me some time :p
Edit:
The problem is solved :D, thanx Tryskell for your help :)
Here is the code:
<zone name="lair_of_antharas" type="NoSummonFriendZone" shape="Cylinder" minZ="-8708" maxZ="-5708" rad="4500">
<node X="177302" Y="114789" />
</zone>
I make a Cylinder of 4500 range.
minZ and maxZ when the coordinate Z is negative, the numbers are reverted, like in this case, minZ="-8708" maxZ="-5708".
The center of the Cylinder is X="177302" Y="114789", and thats all :)
Thanx to all for help me. Close the topic.
