buff/spell reuse after

"buff reuse after xxx" should never set a spell if the spell is not active.

No, not really, because I want update a buff only, If it was set "by hand" before.

What I can is

... to detect if the buff is running or not.

...set a buff if its not running.

but

I want to (re)set a buff only if it was already set.

I dont want set the buff, if its not running before.

I have a lot of poisons. And mostly a rogue use Leeching ... and Deathly ... for solo fights. But in raids I dont need Leeching. Maybe crippling is a better choice. In this case I set i.e. Crippling. No Problem at all. What I want is, that now Cripping was renewed, until it is changed from me to another poison.

(its not very important but would be a nice feature.)

But maybe it could be done by another suggestion that I have: it is possible to use global variables ? Variables that could be set by one Lua-script and read from another ?

With this, I could also realise this.

Try this code lua:

timeLeftToCastAgain > max time left before casting again buff in seconds

minSpellDuration > To ignore spells like Avenging Wrath (combat spell) in seconds 

local timeLeftToCastAgain = 10;
local minSpellDuration = 60 * 2;
for i=1,40 do
	local name, rank, icon, count, debuffType, duration, expirationTime, unitCaster, isStealable, shouldConsolidate, spellId = UnitBuff("player", i); 
	if spellId and unitCaster == "player" then
		local expireTimeLeft = expirationTime-GetTime();
		if (expireTimeLeft >= 0 and duration > minSpellDuration and expireTimeLeft < timeLeftToCastAgain) then
			CastSpellByName(name);
		end
	end
end

Tell me if don't works or if you don't understand (or if is not what you want).

Thanks. Could be closed.

I will use parts of this. I think i will do my own code, because for rouges I have only to check 7 spells/poisons, and I know which one I want to reuse. so i dont have to check all 40 possible buffs.

My solution:
