Event Recognition Lua script help

[Diavol]

So I'm fine tuning all my lua macros and scripts, and I am noticing that at certain times, such as bg's, my healing script on my paladin will try to spam heal someone who is in range, but is line of sighted...
So my question would be, is there a way to track certain events and turn them into variables within a macro or script? I'm assuming there is considering there was a script for recognizing when you are behind someone, though I never dl'd in time before NA blew up...
Any ideas or help on this would be greatly appreciated.

I wrote the behind target check script. This should work the same way, but I haven't tested it:

if not LoSCheck then
    LoSCheck = CreateFrame("Frame")
end

local frame = LoSCheck
frame:RegisterEvent("UI_ERROR_MESSAGE")
frame:SetScript("OnEvent", function(self, event, ...)
	local msg = select(1, ...)
	if (msg:find("sight") ~= nil) then
		LoS=1
	else
		LoS=0
	end
end)

This creates a frame that monitors error message and once it captures the error "You must be in line of sight" or whatever it says, it will return true, so you call it using LoS==1 if your target is not in line of sight. I think. And I believe you need to add a GetTime function as well. Like I said, haven't tested but this should get the ball rolling.

I love your face. I will test this out when I get home

Hmmm I'm having a hell of a time trying to call it from sdm. I can't seem to get the syntax right for adding it as a check before my main healing section...

I'm guessing something like this, but integrating it into your entire script will be a bit challenging and I don't have any time these days:

if not LoSCheck then
    LoSCheck = CreateFrame("Frame")
end

local frame = LoSCheck
frame:RegisterEvent("UI_ERROR_MESSAGE")
frame:SetScript("OnEvent", function(self, event, ...)
	local msg = select(1, ...)
	if (msg:find("sight") ~= nil) and cd("Holy Shock")==0 then
		c("Holy Shock",p)
	else
		c("Flash of Light",t)
	end
end)

c("Flash of Light",t);

Well I have been trying a lot of different ways to get this to work, but its just not for me. All samples I have run check syntax fine but produce no results. Do you by chance have the behind target check script you could send me? I want to make sure Im not missing something...
