Help with script

[Bless]

How would i make these scrips check if no 1 is in, and then clear mobs when no 1 is in... and then spawn more when some 1 goes in...i want only 1 person in room at a time and when no 1 is in room. clear the mobs..also at end ov event if they clear mobs give them a item.

38,42,140 for coords and radius seems wrong to me.

I would expect the coordinates to be at the center of the map and the radius to be approximately half the xx or yy dimensions.

eg - a map of 250 by 350, centre would be 125,175 and radius anywhere between 125 and 175.
