We have a system which communicates the same message to a couple dozen objects at once. Currently they are within the 20m say-range, but we anticipate needing to talk further afield. Possibly several dozen such listening objects. Does anyone have solid numbers on what's better to use in that situation, llSay, lLShout, or llRegionSay?
My concern with the calls that filter objects on range is how much work it is to know what objects are in range. llRegionSay sidesteps that and addresses all objects listening on that channel, with no concern as to how far away they are. I think that would be more efficient. But perhaps the grid is already very efficient on knowing what objects sre in range of what other objects?
