hi i signed onto the site it asked me to. :).
can i talk to ya now more ?
im not sure if i am in wrong place to send e mail to you still
i still ahving problems with the ball script this is the script at the moment
how it stands with 1 ball working fine and i have been trying to add another
ball to the script.
i coppied the txt and added a location2 aswell as location. but it didnt seam
to work :S
