CurTime() Timer

Garry's Mod coding
#1

Hello i made a timer that counts down to zero using CurTime() but when i remove or add a another entity it just goes synced.Lets say i spawned my entity it starts to count down from 120 5 seconds have passed its 115 now i remove the entity spawn it again after 5 secs and it says 110 seconds.

init.lua


AddCSLuaFile( "cl_init.lua" ) 
 include('shared.lua')
 local timecount = 120

function ENT:Initialize()
	self:SetModel(  "models/props_lab/crematorcase.mdl" )
	self:PhysicsInit( SOLID_VPHYSICS )      
	self:SetMoveType( MOVETYPE_VPHYSICS )   
	self:SetSolid( SOLID_VPHYSICS )         
 	self:SetUseType(SIMPLE_USE)
        local phys = self:GetPhysicsObject()
	if (phys:IsValid()) then
		phys:Wake()
	end
end
 local m = CurTime()



function ENT:Think()


self:SetNWInt("time", timecount - (CurTime() - m));	   
   
end

cl_init.lua


include("shared.lua")

function ENT:Initialize()
end

function ENT:Draw()
	self:DrawModel()

	local Pos = self:GetPos()
	local Ang = self:GetAngles()

	local owner = "Time: "..self:GetNWInt("time").."s"; 

	surface.SetFont("HUDNumber5")
	local text = "AAA"
	local TextWidth = surface.GetTextSize(text)
	local TextWidth2 = surface.GetTextSize(owner)

	Ang:RotateAroundAxis(Ang:Up(), 90)

	cam.Start3D2D(Pos + Ang:Up() * 11.5, Ang, 0.11)
		draw.WordBox(2, -TextWidth*0.5, -30, text, "HUDNumber5", Color(140, 0, 0, 100), Color(255,255,255,255))
		draw.WordBox(2, -TextWidth2*0.5, 18, owner, "HUDNumber5", Color(140, 0, 0, 100), Color(255,255,255,255))
	cam.End3D2D()
end

if i was not clear i am trying to make it so evertime i spawn it it stars to countdown from 120 again.it doenst stop counting when i remove it .Any help is appericated !

Is there a particular reason you want to use CurTime() over a timer? If not, try this:

[lua]AddCSLuaFile( “cl_init.lua” )

include(‘shared.lua’)

local function doTime()

timeCount = 120

timer.Create( “countTimer”, 1, timeCount, function()

timeCount = timeCount - 1

end)
end

function ENT:Initialize()

self:SetModel( “models/props_lab/crematorcase.mdl” )
self:PhysicsInit( SOLID_VPHYSICS )
self:SetMoveType( MOVETYPE_VPHYSICS )
self:SetSolid( SOLID_VPHYSICS )
self:SetUseType(SIMPLE_USE)

local phys = self:GetPhysicsObject()

if (phys:IsValid()) then

phys:Wake()

end

doTime() – Calling it on Init should reset the timer each time, since it gets set each time doTime() is called.
end

function ENT:Think()

self:SetNWInt( “time”, timeCount )

end[/lua]

Well i try to avoid usage of timers since i heared that it is not brilliant for multiple entities do you think that it would cause problems if multiple ppl was using this at the same time in my server ?

EDIT : there is a issue with this code i run it and it works perfectly with a single ent but multiple entitys is still buggy.I spawn one of my entity it works fine and lets say 100s left when i spawn antoher one it just sets back to 120s.

This is how I would do It
[lua]
AddCSLuaFile( “cl_init.lua” )
include(‘shared.lua’)
local timecount = 120

function ENT:SetupDataTables()
self:NetworkVar(“Float”, 0, “Timer”)
end

function ENT:Initialize()
self:SetModel( “models/props_lab/crematorcase.mdl” )
self:PhysicsInit( SOLID_VPHYSICS )
self:SetMoveType( MOVETYPE_VPHYSICS )
self:SetSolid( SOLID_VPHYSICS )
self:SetUseType(SIMPLE_USE)
self:SetTimer(CurTime() + timecount)
local phys = self:GetPhysicsObject()
if (phys:IsValid()) then
phys:Wake()
end
end

function ENT:Think()
end[/lua]
I’d create the timer when the ent initializes.

#5

How do we get a valvue from a networked float ? I have seen the wiki but i get errors from using self:GetTimer()

#6

if you wanted to get the time in seconds do
[lua]self:GetTimer() - CurTime()[/lua]
and what errors are you getting?

#7

Well i achieved what i was trying to do but now it gives a error everything works fine though.
my code
init


AddCSLuaFile( "cl_init.lua" ) 
include('shared.lua')
local timecount = 120



function ENT:Initialize()
	self:SetModel(  "models/props_lab/crematorcase.mdl" )
	self:PhysicsInit( SOLID_VPHYSICS )      
	self:SetMoveType( MOVETYPE_VPHYSICS )   
	self:SetSolid( SOLID_VPHYSICS )         
 	self:SetUseType(SIMPLE_USE)
	self:SetTimer(CurTime() + timecount)
    local phys = self:GetPhysicsObject()
	if (phys:IsValid()) then
		phys:Wake()
	end
end

cl init


include("shared.lua")

function ENT:Initialize()
end

function ENT:Draw()
	self.Entity:DrawModel()
	
	local Pos = self:GetPos()
	local Ang = self:GetAngles()
	
    local owner = self:GetTimer() - CurTime()
	
	surface.SetFont("HUDNumber5")
	local TextWidth3 = surface.GetTextSize(owner)
	
	Ang:RotateAroundAxis(Ang:Up(), 90)
	
	cam.Start3D2D(Pos + Ang:Up() * 6.2, Ang, 0.11)
	    draw.WordBox(2, -TextWidth3*0.5, -8, owner, "HUDNumber5", Color(255, 255, 255, 100), Color(0,0,0,255))
	cam.End3D2D()
end

function ENT:Think()
end

....error attempted to call method GetTimer (a nil valvue)
#8

instead of
local timecount
do
ENT.timecount or ENT.TimeCount
and rename every “timecount” in the code to self.timecount
self. makes a value unique to the entity, local makes it global

I didn’t really read much of this thread but to answer the guy who was saying “Why not use timers instead.” The answer is prediction. Using timers messes with prediction why CurTime doesn’t.
