Get your lua script to target the npc you want, with examples

[choweyiii]

You will need to add some things at the end of your .lua so the script knows which npc you're talking about, this will teach you some basics, with a cheesy example, and how to remove events on bosses (so the players are not in combat once the creature is dead).

You can name the .lua file whatever you want, as long as the things inside are correct, I'm very tired, so some of these may be mistakes, correct me if i'm wrong, please!

Feel free to change the messages.
PM me if you need some more help, I'm a noob to scripting, but I think I've got the basics down.

For gossip NPCs add:

RegisterUnitGossipEvent(NPC ID GOES HERE, 1, "On_Gossip")
RegisterUnitGossipEvent(NPC ID GOES HERE, 2, "Gossip_Submenus")
end

For bosses:

function CreatureNameGoesHereWithCaps_OnCombat(pUnit, Event)
local RandomTalk=math.random(1, 3);
if RandomTalk == 1 then
pUnit:SendChatMessage(14, 0, "rarr you pulled me") 
elseif RandomTalk == 2 then
pUnit:SendChatMessage(14, 0, "im cummin to getch ye")
elseif RandomTalk == 3 then
pUnit:SendChatMessage(14, 0, "it's a one in three chance to see this message, personally, i think this one is the best, arn't you lucky")
end
end

function CreatureNameGoesHereWithCaps_OnDied(pUnit, Event)
pUnit:SendChatMessage(14, 0, "oh noes im deads")
pUnit:RemoveEvents()
end 

function CreatureNameGoesHereWithCaps_OnLeaveCombat(pUnit, Event)
pUnit:SendChatMessage(14, 0, "this is what i yell when i leave combat, like when players wipe or run away!")
pUnit:RemoveEvents()
end

function CreatureNameGoesHereWithCaps_OnKilledTarget(pUnit, Event)
local RandomText=math.random(1, 3)
if RandomText == 1 then
pUnit:SendChatMessage(14, 0, "pwned")
elseif RandomText == 2 then
pUnit:SendChatMessage(14, 0, "this is what i yell when i kill somthing")
elseif RandomText == 3 then
pUnit:SendChatMessage(14, 0, "l2p")
end
end

RegisterUnitEvent(NPC ID GOES HERE, 1, "CreatureNameGoesHereWithCaps_OnCombat") 
RegisterUnitEvent(NPC ID GOES HERE, 2, "CreatureNameGoesHereWithCaps_OnLeaveCombat") 
RegisterUnitEvent(NPC ID GOES HERE, 3, "CreatureNameGoesHereWithCaps_OnKilledTarget")
RegisterUnitEvent(NPC ID GOES HERE, 4, "CreatureNameGoesHereWithCaps_OnDied")
end

Good Luck!

I don't think the title of the thread fits the content at all - I have no clue how it is related to it - but you've done your best to contribute, which gets my rep.

Nice, hopefully helps somebody in some way

I think he's trying to teach how to link script with creature if I'm not mistaken?

[pantryboy]

You're linking the script with the creature, as MaCAppLeBiTeMe said... If you didn't do this the script would do nothing.
If you wanted to make a script select a specific creature, you would spawn it in-game, get it's SQL Id and do this:

local creature = Unit:GetUnitBySqlId(...)

Then you can invoke actions on the creature variable.
