Small problem, bug perhaps?

[DaynNight]

Hello Ownedcore, so I recently started to work on a new boss with some great ideas, now i've ran into an issue which I am clueless about since it does not give an error in world.exe or what so ever.

So basicly what I want is when players get in approx 40 yard distance (or less) that the boss will say something and continue with a small cinematic. I've made a trigger npc but still it doesnt work (thought that the boss might stand to high on the throne so I made a trigger npc). Now I spawned everything but when I get into 40 yards of the trigger (or less) nothing happens, no error shown in world.exe.



As you can see the trigger is on the ground and the boss is standing in front of the throne.

Script I currently have which does not function right:

local BossEntryID = 77002
local GuardDosEntryID = 77001
local GuardUnoEntryID = 77000
local TalkTriggerEntryID = 66000

function TT(pUnit, event)
	TalkTrigger = pUnit
end

function GA(pUnit, event)
	Boss = pUnit
end 

function GAN(pUnit, event)
	GuardDos = pUnit
end 

function GR(pUnit, event)
	GuardUno = pUnit
end 

RegisterUnitEvent(BossEntryID, 18, "GA")
RegisterUnitEvent(GuardDosEntryID, 18, "GAN")
RegisterUnitEvent(GuardUnoEntryID, 18, "GR")
RegisterUnitEvent(TalkTriggerEntryID, 18, "TT")

function Boss_OnSpawn(pUnit, Event)
        Boss:SetFaction(14)
		Boss:SetCombatCapable(1)
		Boss:Root()
		Boss:WipeTargetList()
		GuardUno:SetFaction(14)
		GuardUno:SetCombatCapable(1)
		GuardUno:Root()
		GuardUno:WipeTargetList()
		GuardDos:SetFaction(14)
		GuardDos:Root()
		GuardDos:SetCombatCapable(1)
		GuardDos:WipeTargetList()
        Boss:RegisterEvent("Check_For_Players_Boss", 2000, 0)
end

function Check_For_Players_Boss(pUnit)
        local plr = pUnit:GetClosestPlayer()
        if plr ~= nil then
                if TalkTrigger:GetDistanceYards(plr) < 40 then -- Replaced "pUnit" by "TalkTrigger" both didnt work
                        Boss:SendChatMessage(14,0,"Well well, what do we have here..")
                        Boss:RegisterEvent("BossCinematic1", 4000, 1)
		end
	end 
end

I hope someone can help me out.

You need to print. Print as if your life depends on it, it is the easiest way to debug!

function OnSpawn(pUnit, Event)
print(pUnit) -- pUnit should be a unit value and not nil, if you see a 1 digit number you know you have the wrong data type (perhaps Event?) see why debugging helps
local plr = pUnit:GetClosestPlayer()
print(plr) -- Do same with plr
if plr ~= nil then
if plr:GetdistanceYards(pUnit) < 40 then
print("player is within 40 yards")
end
end
end
