Player saying somthing

[Xmaily]

If i wanted a player to say somthing on picking up a quest what would i do?

I have

function Carlosintro1(pUnit, event)
local pla = pUnit:GetClosestPlayer()
if pla == nil then
else
pla:SendChatMessage(14, 0, "What the f-")

Anyone know how to make a player say somthing using LuA?

It's giving me a msg saying player is a nill value

Aswell my script won't make the npc follow...

function OnQuestAccept1(event, pPlayer, questId, pQuestGiver)
if (questId == 30002) then
pUnit:SetUnitToFollow(player, 2, 1)
player:GossipComplete(player)
end
end

RegisterServerHook(14, "OnQuestAccept1")

function Carlosintro1(pUnit, event)
	local pla = pUnit:GetClosestPlayer()
	if pla then
		pla:PlayerSendChatMessage(14, 0, "What the f-")
	end
end

function OnQuestAccept1(event, pPlayer, questId, pQuestGiver)
	if (questId == 30002) then
		pQuestGiver:SetUnitToFollow(pPlayer, 2, 1) -- pQuestGiver and pPlayer, not pUnit and player
	end
end

RegisterServerHook(14, "OnQuestAccept1")

Try setting the creature to guard type 2 in creature_proto.

Try setting the creature to guard type 2 in creature_proto.

Just tried it but he still stops following when he leaves combat. I gave him ai_agents would those effect it at all?

Also regarding the first post i just got to test the script after making the changes and the get the error:

Player is nil value
Pla is nil value

Here is the script

    local CarlosAEntryID = 90004
    local InvisAEntryID = 90005
    local OBJECT_END = 0x0006
    local GAMEOBJECT_BYTES_1 = OBJECT_END + 0x000B
     
    function CLO(pUnit, event)
            CarlosA = pUnit
    end
     
    function INS(pUnit, event)
            InvisA = pUnit
    end
     
    RegisterUnitEvent(CarlosAEntryID, 18, "CLO")
    RegisterUnitEvent(InvisAEntryID, 18, "INS")
     
    function OnQuestAccept(event, pPlayer, questId, pQuestGiver)
	    if (questId == 30001) then

I thought that WoW uses C++...there are some LUA involved?

I depends on the Core your using for example Trinity is only C++ but Arcemu is LuA.

Oh alright I use Arcemu.

TrinityCore with Eluna supports Lua.

Harry i made a simple script to try and fix the problem but it says Unit is a nil value.

function carlosfollow_OnSpawn(Unit, Event)
end

function carlosfollow_OnCombat(Unit, Event, Plr)
	Unit:RemoveEvents()
end

function carlosfollow_OnKilledPlayer(Unit, Event, Plr)
end

function carlosfollow_OnLeaveCombat(Unit, Event, Plr)
target = Unit:GetClosestPlayer()
        Unit:SetUnitToFollow(pPlayer, 2, 1)
	Unit:RemoveEvents()
end

function carlosfollow_OnDied(Unit, Event, Plr)
	Unit:RemoveEvents()
end

RegisterUnitEvent(90004, 1, carlosfollow_OnCombat)
RegisterUnitEvent(90004, 2, carlosfollow_OnLeaveCombat)
RegisterUnitEvent(90004, 3, carlosfollow_OnKilledPlayer)
RegisterUnitEvent(90004, 4, carlosfollow_OnDied)
RegisterUnitEvent(90004, 18, carlosfollow_OnSpawn)

Aswell just for future references how can i make him unfollow?

[stoneharry]

Unit:SetUnitToFollow(pPlayer, 2, 1)

What pPlayer? Where is that defined? You have a target, maybe you should follow that.
