function GM:Initialize()
	CreateConVar("test_roundtime", "360", true, "Sets the time per round")
	CreateConVar("test_preptime", "12", true, "Sets how long preparation takes")
	CreateConVar("test_breaktime", "6", true, "Sets how long preparation takes")
end

-- More code in here, not applicable

local round = {}
	round.intermission	= GetConVar("test_breaktime"):GetInt()
	round.time			= GetConVar("test_roundtime"):GetInt()
	round.prep_time		= GetConVar("test_preptime"):GetInt()
	round.in_progess	= false
	round.count			= 0
	round.timeleft		= -1
	round.status		= "STALE"

What am I doing wrong? First time making ConVar's. The idea is to let the server owner/admins set the times they want to use for said values.[/QUOTE]

You're creating the convars in Initialize which is called after the gamemode is loaded, however it looks like you're attempting to get the convars outside of any block probably meaning before they're created. That's where the index nil error is coming from because GetConVar returned nothing.

Just create the convars outside of any blocks.

Also CreateConVar returns the created convar object so you won't have to call GetConVar.

I have a question about Render Targets. I'm trying to create an animation system for Garry's Mod so cut-scenes can happen on the client's end. I wanted to take advantage of render targets, and while I did manage to get it to work, finding which hook to use has been troublesome.

Here's a short video showing the effect:
[video]https://youtu.be/67xLSy6MyAo[/video]

The trouble is that the hook I'm using is turned off while the main menu is visible, meaning the overlay won't be visible at all. That's a problem - I want it to be visible, even while the main menu is opened.

Here's the problems I've had with these hooks I've tried:

[U][B]CRASH[/B][/U]
PostDrawOpaqueRenderables
PreDrawEffects
RenderScreenspaceEffects
PostDrawEffects
PreDrawHUD
PostDrawHUD

[B][U]Doesn’t work[/U][/B]
HUDPaintBackground

[B][U]Doesn’t render while in main menu[/U][/B]
HUDPaint

[B][U]Renders over GUI[/U][/B]
DrawOverlay

Any ideas?

EDIT: Here's the script, if that helps.

[LUA]
AddCSLuaFile()

if not CLIENT then return end

local rt_cam_pos = Vector(-3057, -1471, -77)
local rt_cam_ang = Angle(0, 177, 0)

local rt_mat = Material("rt_test/rt_add")
local rt_tex = rt_mat:GetTexture("$basetexture")

hook.Add( "HUDPaint", "HUDPaint_RT_TEST", function()
local old_rt = render.GetRenderTarget()

render.SetRenderTarget(rt_tex)
local cam_data = {}
cam_data.angles = rt_cam_ang
cam_data.origin = rt_cam_pos
cam_data.fov = 9
cam_data.x = 0
cam_data.y = 0
cam_data.w = ScrW()
cam_data.h = ScrW()
render.RenderView(cam_data)

render.SetRenderTarget(old_rt)

render.SetMaterial(rt_mat)
render.DrawScreenQuad()
end)
[/LUA]

EDIT:

Here's also the VMT I made called rt_add:

"gmodscreenspace"
{
	"$basetexture" "_rt_FullFrameFB1"
	"$additive" 	1
	"$vertexcolor" 	1
	"$vertexalpha" 	1
}

[QUOTE=sannys;51780126]You are blowing this so out of proportion. He asked for a simple hook.[/QUOTE]

The problem with solving questions on here is that there are many ways to do something, but only one way is actually designed to solve the given problem, and other methods may even cause more. When someone asks to solve a specific problem, they are sometimes trying to solve a problem caused by solving another problem badly.

This is why it is important to make sure this isn't an X-Y problem, where a user has problem X causing problem Y, but only gives information pertinent to Y.

Txike's problem sounds very much like an X-Y problem. Why do you need to know if a file is being reloaded? If your implementation of something is correct, then you have no need to know if it is being reloaded, otherwise try instead solving the bad implementation, rather than the symptoms of the problem it is causing.

In any cause, here is an easy way to know if your file is being reloaded:

[lua]
if ( FILE_ALREADY_LOADED ) then
print( "This file is being reloaded" )
end
FILE_ALREADY_LOADED = true
[/lua]

The variable FILE_ALREADY_LOADED is only set after the check. Therefore, if it is true during the check, then the file is being reloaded. This method is standard practice in CPP, where header files may be included multiple times, causing redefinition problems, however, you don't know which file is including it first without following every include tree.

[raubana]

I solved my problem. The trick is to place the part where the RT is rendered to in a separate hook (PreRender works), and then render to the screen in the RenderScreenspaceEffects hook.

As in the quote you are using, I was giving my reason for suspecting it was an XY problem. If you need me to further elaborate:

The only reason you would need to know if a file is being reloaded is because their behaviour is being changed between reloads. If a file runs the same before and after a reload, then they are equivalent, and need no knowledge of a reload. This also explains the solution I provided; As files reload on a file by file basis, then it makes sense that he only needs to check a specific file if it is being reloaded.

To cut this short, there is no hook that tells you if a file has been reloaded, only entire gamemodes, entities or weapons.

I don't understand why you are defending Txike without understanding our reasons for saying he is having an XY problem. You say we are "accusing" him, as if our suggesting his problem might be one he hasn't considered is a bad thing. You say I have no bussiness asking, when I'm attempting to provide a solution and you aren't. You say I have no tangible reason (as if reasons are anything BUT tangible) to suspect he is doing something wrong, without reading my explination in the post you quoted.

TLDR: Feel free to defend a guy from immagined accusations, but atleast try and provide a solution yourself beforehand.

He never asked how to check if a file was reloaded. He asked how to check if there was a lua refresh.

I'm going to leave it at that because this isn't something even worth arguing about.

[tehbiga]

How about instead of a bunch of hacks we just get the hook many have wanted for years? I've wanted a refresh hook for quite a while so that I don't have to put garbage at the top of every file I need to keep an eye on.

At one point I just went OOP entirely so that I can track object registration and refresh my addon gracefully. I like to avoid map reloading when developing so I reload gamemodes and addons instead. A hook for file refreshes would assist with this.

[b]Also I'm sick of unhandled refreshes and I'd want this hook to allow returning true or something to force the reload.[/b] This is the real gear grinder.

ScrW() = 1600
w = 363
padding = 10
ScrW() - w - padding = 1227
w - padding = 353

1227 + 353 = 1580. It must be an order of operations problem, but how?[/QUOTE]

Don't exactly know what you're asking, but your last equation should be w + padding since the fourth equation is really two separate operations, and can be written as ScrW() - (w + padding)

Everything else works and it's getting on my nerves that I can't figure out how to keep velocity the same... :\

[Mr.Pilot]

Quick ignorant question time!!!

What's the most efficient way to set the position of surface.DrawTexturedRect(0,0,50,50) so that it's on the bottom of the screen instead of the top?

[nubpro]

What would be ideal solution to cap a player's velocity?

For example, Player A is bhopping at 350 velocity, instead of going over it, I would want his/her velocity to be capped at 350 till it's interrupted naturally.

I'm quite confused how SetVelocity() would work in this case.
If someone would point me into the right direction, that would be great!

Codes snippets I took from a post:

local MAX_SPEED = 260
function speedLimiter(ply, data)
	local speed = ply:GetVelocity():Length()	
	if speed > MAX_SPEED then
		ply:ChatPrint("Speed Length: ".. speed)
		ply:ChatPrint("Velocity: ".. tostring(ply:GetVelocity()))		
		ply:ChatPrint("Speed limit over "..MAX_SPEED )	
		ply:SetVelocity(ply:GetVelocity())
	end
end
hook.Add("Move", "Speed Limit", speedLimiter)

When the velocity is greater than the max, simply set it back to the max.
