What is the best linden script to show a stream of light-glow pulses, and to change the speed or width of some of hte pulses, or colour too? The size of the tube they travel in changes . The trigger information has to come from the avatar who uses it - settings in a HUD. I saw something on youtube about a person who designed a beautiful hud to operate all kinds of bullets for a weapon. So, I was half thinking of trying to adapt of modify the script for both of those but of course, those are proprietary and not visible. Maybe there is a better way. I saw the script suggestion for changing lights around a frame but in this case,I would like changing sizes of pulses inside , not outside. Maybe there is not much diff... Has anyone tried something similar? :heart: :matte-motes-kiss:
