Subject: Percentage chance for item loading
This is a patch for percentage loading. Apply the changes and
then add a number between 1 and 100 to the MOEPG lines, for
which you want percentage loading, in the zone files. The number
is the chance that the obj/mob will not load. So with a number
of 100 it is only 1% chance that the load will occur.
New format for the zone commands. (The load chance is not needed
if the obj/mob should always pop.)
M <if-flag> <mob vnum> <max existing> <room vnum> <load chance>
O <if-flag> <obj vnum> <max existing> <room vnum> <load chance>
G <if-flag> <obj vnum> <max existing> <load chance>
E <if-flag> <obj vnum> <max existing> <equipment position> <load chance>
P <if-flag> <obj vnum 1> <max existing> <obj vnum 2> <load chance>
