Help with net Server to Client!!

[DubyxD]

Hi guys I need help understanding something. I have been trying to get this working for some time now and I have looked every where but no luck. So I hope today you can help explain and show me where I am going wrong!

I am trying to get a timer to work with my round system. I have been trying to do this for ages, but the way perhaps or my knowledge is incorrect on how to do it. So this is what I have.

[B]Server side[/B]

function round.Begin()

if round.Begin then

util.AddNetworkString("myMessage")
net.Start("myMessage")
net.Broadcast = ply

end

end

[B]Client side[/B]

function hud()

local timeleft = math.Round(math.max(0, roundend - CurTime()), 2)

net.SendToServer ("myMessage", function(length, client)

draw.SimpleText( timeleft,"MyFont2", ScrW() / 2 - -700, ScrH() - 1000, Color(220, 78, 78, 255),TEXT_ALIGN_CENTER)

end)

end

I have been trying to understand this server to networking for ages now. Also please just don't link this. As I have been reading it and trying it for ages.

Thankyou very much for any support. I have to gain an understanding from this.

Please use [noparse]

[/noparse] tags in the future, though I fixed it anyway for the purposes of this quote.
[b]Server[/b]

util.AddNetworkString("roundstart") -- Renamed the netmessages.
util.AddNetworkString("roundend") -- It's better to define this at the top of your init file. I also renamed it.

function round:Begin() -- use : instead of .
    if round.Begin then -- what is round.Begin? Have you defined it anywhere? I presume you have.
	net.Start("roundend")
	net.Broadcast() -- it's just net.Broadcast(), no need for ply.
    end
end

[b]Client[/b]

local roundended = false

function hud() -- assuming this is using the HUDPaint hook there's no reason to change it.
    local timeleft = math.Round(math.max(0, roundend - CurTime()), 2) -- what's roundend? where was it defined?

    if roundended == true then
        draw.SimpleText( timeleft,"MyFont2", ScrW() / 2 - -700, ScrH() - 1000, Color(220, 78, 78, 255),TEXT_ALIGN_CENTER)
    end
end
hook.Add("HUDPaint", "RoundHUD", hud)

net.Receive("roundstart", function(length) -- net.Receive, not net.SendToServer().
    roundended = false
end)

net.Receive("roundend", function(length) -- net.Receive, not net.SendToServer().
    roundended = true
end)

This is as much as I can help you without further details or error logs.

Instead you should have put the net.Receive outside the hud function and used hook.Add() to call the hud and then use hook.Remove() when he's done, instead of adding a net.Receive every frame.

Yes, that would have been ideal, I did not want to confuse him too much though.

If it were me, I would define it separately then set something like "roundended" to true, and only draw that text if "roundended" is true.

Fixed it. Thanks.

[DubyxD]

Hmmmmm Very intresting. I really appreciate the fact that you took the time to comment it. Thankyou very much. :) I will look closely at how this works and try and apply it to other things.

Hmm the timer isn't appearing on my screen. I don't have any error's on my console either. But it also creates a time out for joining. 'this is for a gamemode if you didn't know'

[Mitsudigi]

Looks like you didn't [url=http://wiki.garrysmod.com/page/Net_Library_Usage]check the usage tutorial[/url] first.

Quite a lot of mistakes were made contrary to the information provided there.

Good luck with your gamemode though.

[DubyxD]

Thankyou for the good luck. But *facepalm* You didn't read what I posted correctly. I have read this 100s of times and I am stuck with getting it to work. Thus I need someone to show me how it can work with this correctly above ^. Then I can learn how to use it with other things..
