I am nearing alpha on my Chernarus Electrical Grid script pack, which is the sequel to Sahrani Electrical Grids for A1 which simulates an entire Island Electrical Grid to include switching lights on and off. There are over 1000 street lamps on Chernarus and some of them arre off by themseleves near nothing else so it takes a bit to find them all. I have an algorithim that finds them all using nearObjects in a series of small radii (500m or less) and and switches them off systematically using switchLight. I do it like this because if you try to switch them all off in one big radius (like 11000m outward from Novy Sobor) it causes a LOT of lag (several seconds).
The algorithim is lengthy and is meant to be executed in stages, but I am happy to post it when I get home tonight (I don't have it with me at work).
And just to note, switchLight is a local command, so it has to be run on all machines to have full effect or some players will have lights on and some off if MP and you only run it local.
Update:Ok, here you go. It's not really an algorithm, it is more of a brute force method
. This is not totally pretty and clean as I ripped it from my larger script pack to make it more universal, but the below script will switch off every street lamp in Chernarus. The caveats being:
1) The switching code is laggy (5-10 secs) unless you use the include startLoadingScreen/endLoadingScreen commands.
2) It will only turn off street lamps. Tower lights, traffic signals, and ALICE houselights are not affected (there is away to turn off ALICE lights but we can cover that later if necessary).
Here is how it works. The script creates an array of circle positions and radii that I have pre-compiled to cover every street lamp on the island and tailored the radii to only cover the lamps. It then iterates through each one of these search radii finding it street lamp with nearObjects and uses switchLight to turn each light off. I have included some additional code (and script) that if used will verify that every light is off and if not will put a yellow dot marker at its location. Just comment/remove it if you don't want to use it.
Regarding startLoadingScreen/endLoadingScreen, if you are unfamiliar with them, they are a fantastic combo that halts the game simulation and scene drawing so that scripts run at full speed. Without them, it would take about 10 secs (on my slow machine) to iterate though all of the lights. With them at mission start (i.e. script launched from init.sqf or unit init line), it only adds a few seconds to the "Receiving..." screen (you never see "initializing..." unless you run the script AFTER mission start). I am working on further optimizing the searches to avoid lag all together that will take me some more time (days to weeks) and is part of my bigger overall project. So, enough intro, here is the code (warning: long):
