Requesting help with Ready = true/false stuff.

[BurnDownTheSystem]

Hi, im very sorry if I explain this bad.. my english aint so good/lack of sleep.

So I want to create this basic gossip script: talking to a creature which will check if every hostile unit in the area / with id 525003 is dead OR alive, if they all are dead I want some spawned units to move forward. There is just 1 problem, I have never done a script like this before.. so how do I do this? I have inspected some scripts from several people with for example something like if Ready = false then and if Ready = true then stuff, I have basic experience with the lua commands "if" "else" and "then" could anyone please post an example of a script so I can see how I can do it or just explain to me what is best to do? :confused:

Kind regards

Something like this:

for _,unit in pairs(pUnit:GetInRangeUnits()) do
   if unit:GetAreaId() == 1 and unit:GetEntry() == 525003 then
     if unit:IsAlive() then
       -- Unit is alive
       -- Do something
    else
      -- Unit is dead, do something
    end
  end
end

Thanks it worked, had to remove "unit:GetAreaId() == 1 and" from it otherwise it would bug.

Now I have to find a way that if there are more than 1 npc's alive/dead that it doesnt spam with the message I want him to say, but that aint so hard I guess, got it all planned out in my mind already.

Thanks alot

EDIT: +rep sorry almost forgot

Call 'break' to make that loop stop and for it to move on.

e.g:

for _,unit in pairs(pUnit:GetInRangeUnits()) do
   if unit:GetAreaId() == 1 and unit:GetEntry() == 525003 then
     if unit:IsAlive() then
       -- Unit is alive
       -- Do something
       break
    else
      -- Unit is dead, do something
      break
    end
  end
end

Alternatively you can do something similar with a function:

function CreatureSpawn(pUnit, Event)
	pUnit:RegisterEvent("HandleStuff", 1000, 0)
end

function HandleStuff(pUnit)
	local result = DoStuff(pUnit) -- We call the function, which will return a value
	if result == 1 then
		-- the unit was alive that we found
	elseif result == 2 then
		-- the unit was dead that we found
	elseif result == 0 then
		-- nothing was found
	end
end

function DoStuff(pUnit)
	for _,unit in pairs(pUnit:GetInRangeUnits()) do
	   if unit:GetAreaId() == 1 and unit:GetEntry() == 525003 then
		 if unit:IsAlive() then
		   -- Unit is alive
		   -- Do something
		   return 1
		else
		  -- Unit is dead, do something
		  return 2
		end
	  end
	end
	return 0
end
