Understanding The basics of Lua Locals!

LOCAL GUIDE!

This is another little guide im making to describe a more advanced yet commonly needed command. The local command. The local command lets you use multiple NPCs in one script.

Ok lets go!!

to start a local value you use the command

local npcname -- this means nothing it is just recognizing the name in the script you can change npcname into anything you want

Now when you start your script you want to name the local value so it means something, for example

function npclolz(pUnit, Event)
npcname = pUnit -- this tells the script that this npc is named that! you can use as many npcs as you want using this!
npcname:SendChatMessage(12, 0, "lol") -- npcname replaces pUnit and does its same function
end

you need to bind each function to an npc id, for example

local npcname
local npcname2

function npcname(pUnit, Event)
npcname = pUnit
end

RegisterUnitEvent(NPC ID, 1, "npcname")

npcname2 = pUnit
function npcname2(pUnit, Event)
end

RegisterUnitEvent(NPC ID, 1, "npcname2")

Thats all i hoped you learned something! have fun!

I think you kinda failed to mention what local does, basically it makes it a local variable (as opposed to global) and the variable must stay in its "scope". For example, if you define the variable as a local variable OUTSIDE a method (Such as a function or conditional statement), then its scope is the entire file. It can be used in every function in the file if needed. If I defined it inside a function as a local variable, then it will be bound to it's scope, which is in this case that function only. It can't be used anywhere else. Hope that helps you clear stuff up You could add some examples of how scope works in your guide and some readable colors that are easy on the eyes and then your set
