EQEmulator Forums - spawn areas

here are the updates to do : ( based on 24-05-2004 source )

first :
download this :
spawnarea.zip

it contains spawnarea.cpp and spawnarea.h
add these files in your project zone folder, and add them to your zone project

then do the following changes ( there is a lot ) and compile :
