Problems with net.SendToServer()

Garry's Mod coding

Hey FacePunch community !

I get a problem with my net.SendToServer…

I’m testing a swep, so here the code :

cl_init.lua



if not LocalPlayer():canAfford(amount_floor) then
	net.Start("fwlt")
		net.WriteString("Testing")
	net.SendToServer()
	return ""
end

init.lua



-- Adding the netstring
util.AddNetworkString("fwlt")

-- When receive the net 
net.Receive("fwlt", print("success"))

I think my code is correct but nothing apear…

I’m sure the if is working, I’ve tested the code with only a print(“success”) in the condition and it was working :confused:

I reallllly hope someone can help me !

Thanks a lot in advance,
Gaby

try this:


net.Receive( "fwlt", function( _Length, _Player )
      print( "success" )
end)

You’re passing both the length and the player into the print function, so in reality it will probably break.

#3

While your code snippet is indeed the correction required, your reasoning is wrong. print(“success”) doesn’t return a function that will print success, it calls the function print with argument success, and returns nil. This means that the second argument in net.Receive is nil, and not a function that can handle net messages.

Hey guys !

Thanks you so much, it’s working now.

I think it can be cool to explain like that on the gmod wiki. Cuz for beginners it’s not really clear ^^

Thanks a lot again,

Gaby
