That doesn't seem to work... Well, it did once, but only one way ('self.Frame = 1;' but not 'self.Frame = 0;'), and now it doesn't...
Also, for some unknown reason, everything started laging. Yesterday I tested the door in both singleplayer and 2player mode and it was lagless, today everything is ♥♥♥♥ up. >:E

If this lag doesn't just 'go away', this thing will end up scrapped...
And honestly, I don't even know what causes the lag... It's definitely not the emitters, because the particles they emit are very short lived, so there aren't really more then 50-70 of them per frame... So it must be the checks... Even though there are only 2 working at a time...

I tried changing all the proximity checks to boxes but it didn't seem to reduce lag.
Is there a better way to trigger the lasers without having to constantly check for them?
I tried adding a proximity check that would make 'emitter = self.laser;' and then use 'self.laser' for whatever I needed, but I ended up with that Ω error BS... Maybe I was doing it wrong?

Sometimes, I really ♥♥♥♥ hate how CC works. >:C

This is the current code, I changed the checks to boxes, but self.Frame doesn't work. See what is wrong.

for one, putting it all in a box that checks positions every 1/3/500 MS using timers should dramatically cut down your lag.
otherwise, your efficiency was pretty bad. http://pastebin.com/m5f9be4e9 enjoy

Hmm, that does actually remove the lag... 300ms is alot though, I changed it to 80.

Now, a new problem occured. It lags like ♥♥♥♥ whenever an AI actor is on scene.
It seems that AI somehow makes ♥♥♥♥ with lua lag...
And the thing seems to break after some time... Like, it stops switching on/off, it always stays on.

Goddamnit.

has a link to another pastebin containing something for major restructuring that i cbf doing now. should fix your lag, considering the gross amount of for loops.
heck, you could create a list early on using some string.find and proximity checks for the emitters so you cant get rid of the particle fors.
