After about an hour or so of tweaking, everything is running perfectly!
Now i can have multiple heat seeking missiles chaotically flying towards different enemies on screen, all with crazy light trails everywhere and it actually looks exactly how I wanted it to! <!-- s:D --><img src="SMILIES_PATH/icon_biggrin.gif" border="0" alt=":D" title="Very Happy" /><!-- s:D -->
