Nice ahref. Been looking forward to this since you mentioned it in developers corner (I think that was where)
I've not tried this (not even re-installed Gmod since my HD crash last week); Does it work from console too? "ulx rocket", etc
Rainbow eh?
How about an extra option?
You seem to already have some basic color settings for when UTeam isn't installed.
How about some primary colors, ignoring UTeam if the admin types "ulx rocket <player> <color>"
Where color could be Red, Green, Blue, Yellow, Orange, Purple, or Rainbow.
Typing rainbow would cycle through colors for multiple people, OR, if individual, use multicolored puffs of smoke. I'm not sure what effect your using...can it be changed every few frames/short time/units?
I dunno, that just sounds like fun.
