Remember Im a novice at LUA. So please give me a detailed explanation so I can learn more. See Im still not sure how to through code together. So im finding other code and editing it to see if I can make it work for what im wanting to do. This is going to be a Disease Manager for DKs. Once the Disease get to 3 sec left of its target debuff then the DK will recast the move according to the disease to reapply it.

 

if not (UnitIsDead("target")) and not (IsFlying("player")) and not (IsResting("player")) and not (UnitIsAFK("player")) then

    --[[ refresh the Diseases on the target if there are less then 3 sec left (to be sure that it dont run out while a fight ]]

Try it

Im going to try this today. And TY for the help. Ill edit this post to let you know if it is working.

Well it seems to work right Im doing some extended teasting. So I will be bck again if I find out it isnt working in the manner Im needing it to.

OK Driodz is not casting Plague Strike to put Blood Plague on the target. Its not doing (1,2,1 do)

meaning that

 

    --[[ Outbreak,Plague Strike ]]
idDiseases[2]={77575,45462}

 

Isnt being used for some reason or kept up on the target. But

 

--[[ Outbreak,Icy Touch ]]
idDiseases[3]={77575,45477}

 

Is being kept up on the target.

 

is there a reason why bot spells aren't being fires consecutively??? to keep the debuffs up on the target?
