This cog is for making Swarm missiles, and yes I do have permission to use it! The problem is, in multiplayer, the missiles do not show up, and no damage is done to the enemy. THe other player is, however, able to hear the sound of them. I need help. I've tried adding the 0X140 flag for multiplayer, but it still refuses to work.
Any suggestions? Here it is:

# The Emperor's Fury Cog Script

# WEAP_HMISSILE.COG
#
# Homing Missile
#
# Level used in - 00
#
# This gun fires homing swarm missiles. First you target the victim by pressing
# fire, and when you release it the missiles home in on the specified
# victim. It cannot be fired when there is no victim and does not
# differentiate between friendlies or enemies, so be careful!
# Before people complain there is a built in level of inacuracy in each missile,
# getting progressively worse.
# There is no form of secondary fire at all.
#
# - Not affected by Magsealed sectors/surfaces (It very rarely hits them

Templates from static.jkl will only be created on the person's computer that called FireProjectile().

You can, however, get around this by using triggers.

There's a tutorial at Millenium about it here.
