Right so I'm working on a crude version of the health/armour chargers but I'm having a bit of bother with implementing an interval timer so the client isn't spammed with a notification every frame while using the charger.
I have a base entity that creates the network variables in the standard ENT:SetupDataTables function, here is the majority of my code from the shared.lua file for the base entity:
-- ENTITY EXTENSION FUNCTIONS
function ENT:SetupDataTables()
self:NetworkVar("Int", 0, "Charge")
self:NetworkVar("Int", 1, "NotificationInterval")
end
function ENT:NotifyClient(ply, text, duration, notificationType)
if not self:CanSendNotification() then return end
if (SERVER && duration >= 0) then
net.Start("notifyclient")
net.WriteString(notificationType)
net.WriteString(text)
net.WriteInt(duration, 16)
net.Send(ply)
elseif (CLIENT) then
SendClientNotification(text, notificationType, duration)
end
end
function ENT:CanSendNotification()
return self.timer + self:GetNotificationInterval() > CurTime()
end
-- OTHER FUNCTIONS
function SendClientNotification(text, notificationType, duration)
-- can easily add more error types if required
if (notificationType == "Error") then
notification.AddLegacy(text, NOTIFY_ERROR, duration)
elseif (notificationType == "Generic") then
notification.AddLegacy(text, NOTIFY_GENERIC, duration)
end
surface.PlaySound("buttons/button15.wav")
end
if (CLIENT) then
net.Receive("notifyclient", function()
local notificationType = net.ReadString()
SendClientNotification(net.ReadString(), notificationType, net.ReadInt(16))
end)
end
Here is my init.lua for my base entity, where I set the NotificationInterval value on initialise:
AddCSLuaFile("cl_init.lua")
AddCSLuaFile("shared.lua")
include("shared.lua")
function ENT:Initialize()
self:SetModel("models/props_c17/consolebox01a.mdl")
self:PhysicsInit(SOLID_VPHYSICS)
self:SetMoveType(MOVETYPE_VPHYSICS)
self:SetSolid(SOLID_VPHYSICS)
local phys = self:GetPhysicsObject()
if phys:IsValid() then phys:Wake() end
self.timer = CurTime()
self:SetNotificationInterval(4)
end
function ENT:Think()
if CurTime() > self.timer + self:GetNotificationInterval() then self.timer = CurTime() end
end
if ( SERVER ) then util.AddNetworkString("notifyclient") end
I have then created a health charger entity that inherits from the base entity briefly described above. In my ENT:Use function below, you can see me calling the base ENT:NotifyClient function I've written when the player's health is full:
function ENT:Use(activator, caller)
if not IsValid(caller) or not caller:IsPlayer() then return end
local plyCurrentHealth = caller:Health()
if plyCurrentHealth >= 100 then BaseClass:NotifyClient(caller, "You are already at full health!", 4, "Error") end
end
So if you refer back to my shared.lua file for my base entity (first spoiler), and look within the NotifyClient function, I call another function by the name of CanSendNotification where I check to see if the interval has been passed. However, I get the following error when I press my use key on the entity in-game:
[ERROR] lua/entities/base_charger/init.lua:30: attempt to call method 'GetNotificationInterval' (a nil value)
1. CanSendNotification - lua/entities/base_charger/init.lua:30
2. NotifyClient - lua/entities/base_charger/shared.lua:18
3. unknown - lua/entities/health_charger/init.lua:23
I feel like this is gonna be a really silly mistake considering it's taken me this long and I still haven't found what I've done wrong. Any help would be appreciated, and yes, I know my scripts are shite pls no hate.
