AddCSLuaFile("cl_init.lua")
AddCSLuaFile("shared.lua")

include("shared.lua")

-- Values

local IngredientsForBread = {'egg_cookingmania', 'flour_cookingmania', 'milk_cookingmania'}
local CookingDelay = 5

-- Networks

util.AddNetworkString("DrawRecipesDerma")
util.AddNetworkString("ButtonBreadClick")
util.AddNetworkString("ButtonCakeClick")
util.AddNetworkString("ButtonCookClick")

function ENT:Initialize()

self:SetModel("models/props_c17/furnitureStove001a.mdl")
self:PhysicsInit(SOLID_VPHYSICS)
self:SetMoveType(MOVETYPE_VPHYSICS)
self:SetSolid(SOLID_VPHYSICS)
self:SetUseType(SIMPLE_USE)
self:DrawShadow(true)
self:SetPos(self:GetPos() + Vector(0, 0, 100))

local phys = self:GetPhysicsObject()

if ( SERVER ) then
self:PhysicsInit( SOLID_VPHYSICS )
end

if phys:IsValid() then
phys:Wake()
end

self.CookersRecipe = "None"
end
function ENT:Use(activator, caller)
if activator:IsValid() and caller:IsPlayer() then
net.Start("DrawRecipesDerma")
net.Send(caller)
end
end

local SelfEntity = FindMetaTable( "Entity" )

net.Receive("ButtonBreadClick", function ()
SelfEntity.CookersRecipe = "Bread"
-- SelfEntity:SetVar("CookersRecipe", "Bread" )
-- SelfEntity:SetCookersRecipe("Bread")
end)

net.Receive("ButtonCakeClick", function()
SelfEntity.CookersRecipe = "Cake"
-- SelfEntity:SetVar("CookersRecipe", "Cake" )
-- SelfEntity:SetCookersRecipe("Cake")
end)

net.Receive("ButtonCookClick", function()
print(SelfEntity.CookersRecipe)
end)
