LUA Example #1 - Scaling an NPC

[KLS]

Just to add to the example you can take it and do something like:

function NPC:Scale(level, zoneid, instanceid, scalerate, loottableid)
	--Set up static constants, these are close to PEQ values:
	local hpval = ((level * (11 + level)) * scalerate) / 100
	local manaval = ((level * (11 + level))  * scalerate) / 100
	local endurval = ((level * (11 + level))  * scalerate) / 100
	local min_dmg = (((level + 2) + level)   * scalerate) / 100
	local max_dmg = (((level * 2) + level)   * scalerate) / 100
	local ac = ((28 + (4 * level))   * scalerate) / 100
	local hp_regen_rate = (((level / 5) + 1) * scalerate) / 100
	local mana_regen_rate = (((level / 5) + 1)   * scalerate) / 100
	local rawstats 	= ((75 + (level * 2)) * scalerate) / 100

	--[[ 
	Lua supports nice looking comments too, so why not tell people we are starting the actual scaling here?
	Maybe include instance version at some point to the equation? :)
	--]]
	
	self:AddLootTable(loottableid)
	self:ModifyNPCStat("str", tostring(rawstats))
	self:ModifyNPCStat("sta", tostring(rawstats))
	self:ModifyNPCStat("agi", tostring(rawstats))
	self:ModifyNPCStat("dex", tostring(rawstats))
	self:ModifyNPCStat("wis", tostring(rawstats))
	self:ModifyNPCStat("int", tostring(rawstats))
	self:ModifyNPCStat("cha", tostring(rawstats))
	self:ModifyNPCStat("ac", tostring(ac))
	self:ModifyNPCStat("max_hp", tostring(hpval))
	self:ModifyNPCStat("mana", tostring(manaval))
	self:ModifyNPCStat("min_hit", tostring(min_dmg))
	self:ModifyNPCStat("max_hit", tostring(max_dmg))
	self:ModifyNPCStat("hp_regen", tostring(hp_regen_rate))
	self:ModifyNPCStat("mana_regen", tostring(hp_regen_rate))
	self:ModifyNPCStat("level", tostring(level))
	self:ModifyNPCStat("healscale", tostring(healscale))
	self:ModifyNPCStat("spellscale", tostring(spellscale))
	self:Heal()
end

and in your global/script_init.lua add
require("lua_scale")

Then you could literally do

function event_say(e)
	e.self:Say("Scaleme!")
	e.self:Scale(e.message, eq.get_zone_id(), eq.get_zone_instance_id(), 100, 1)
end

Inheritance issues can sometimes make it a bit tricky though as these wont be in the metatable lookup that deals with inheritance.

Interesting addition, KLS.

Hopefully this will cut down the need for so many functions that we generally export to perl - except they'll be faster.
