What do you need help with? V3

[jrj996]

I'm trying to toy around with the sun entity "env_sun" and for some odd reason nothing works for me when I try to modify except for ent:Remove(). Key Values don't do anything neither do typical entity functions. Here's my code:

[lua]
concommand.Add("env_suntest",function(player,_,args)
ents.FindByClass("env_sun")[1]:SetKeyValue("Pitch",tonumber(args[1]))
end)
[/lua]

This is just to toy around so I can figure out how to work with it.

tsql = tmysql.initialize(ad, uz, aa, db, 3306)
-- Then later in the file:

Still gives me the same error. This is what you meant right?[/QUOTE]

It's tsql:Query(), not query() I believe.

[QUOTE=Mythikos;37259742]Hey guys, sorry to ask so many questions lol (im still learning) and this thread is awesome because there isn't much help anywhere else :). Im trying to make a command for the gamemode gofish2. The command would allow me to give other players money rather than just myself.
.
This is what I have so far.
[lua]
concommand.Add("gfc_givecash", function(ply, args)
if ply:IsAdmin() then
if args[2] then

local p = args[1]
local num = args[2]

p:SetNetworkedInt("cash", p:GetNetworkedInt("cash") + num)
umsg.Start("MoneyChanged", p)
umsg.Short(p:GetNetworkedInt("cash"))
umsg.End()
else
Msg("Insufficient amount of arguments! gfc_givecash 'name' 'amount'")
end
//end
end)
[/lua]

and This is what the old lua code is.
[lua]
function givecash(ply)
if ply:IsAdmin() then
ply:SetNetworkedInt("cash", ply:GetNetworkedInt("cash") + 500)
umsg.Start("MoneyChanged",ply)
umsg.Short(ply:GetNetworkedInt("cash"))
umsg.End()
end
end
concommand.Add("givecash", givecash)
[/lua]

The error the console is spitting back at me is Lua Error: [@gamemodes\gofish2\gamemode\init.lua:40] bad key to string index (number expected, got string) and note this is happening to my script, not the original.

I am not sure on how to fix this one, or even if im doing it right at that matter. If anyone knows a way/has a better way please tell :). Btw Line 40 is the "p:SetNetworkedInt("cash", p:GetNetworkedInt("cash") + num)" part of the code. Thanks!

Does anyone know how I can find out if an entity was created by world?

The concommand callback's arguments are player, command, arguments. You're attempting to treat a string as an array.

Entity:CreatedByMap()

[QUOTE=Lexic;37276852]The concommand callback's arguments are player, command, arguments. You're attempting to treat a string as an array.[/QUOTE]

Actually, while that is an issue it's not what's causing the error.
[lua]local p = args[1]
local num = args[2][/lua]
args is an array of strings, so both p and num are strings. You need to call tonumber() on num and perform some form of lookup to get the player object.

[QUOTE=Banana Lord.;37269284]have you tried with net.Send( { ply } )[/QUOTE]

Yes, and I'm getting the same result.

I understand but I am not sure how to remedy an issue like this. Possibly can you help further. possibly like an example or something. thanks and sorry :\

Also side note: I am trying to figure out how to set a prop to owner world... I'm using SPP on my server and need to be able to set certain entities to "Owner: World" so other players cant interact with them. I tried the "Entity:SetOwner()" function but it isn't doing what I need. Any help on this would be greatly appreciated!

[jrj996]

Not sure if the issue is in my code or if Garry messed up something in the update but whenever I die my player's ragdoll entity doesn't "spawn". It does a weird camera glitch where it levitates over where my dead body SHOULD be but there's nothing there. Here's the only hooks that could interfere with it that I have:

[lua]
hook.Add("PlayerDeath","Check Match Status",function(victim,inf,pl)
if GAMEMODE:GetAlivePlayers() - 1 == 1 then
if victim != player then
GAMEMODE:EndMatch(pl)
else
--Still working on it
end
end
print("Ran hook.")
end)

hook.Add("PlayerDeathThink","Prevent Match Spawning",function(player)
if GAMEMODE.MatchStarted then
return false
end
end)
[/lua]
Also, this ONLY happens when a bot is spawned. If I don't spawn it or I'm in single player then it works fine.

You have put
[lua]concommand.Add("gfc_givecash", function(ply, args)[/lua]
change it to
[lua]concommand.Add("gfc_givecash", function(ply, cmd, args)[/lua]

I am starting to get it. I just need help understanding one last thing. This is my new code...
[LUA]
concommand.Add("gfc_givecash", function(ply, cmd, args)
if ply:IsAdmin() then
if args[2] then

local p = args[1]
local num = args[2]

p:SetNetworkedInt("cash", p:GetNetworkedInt("cash", 0) + tonumber(num))
umsg.Start("MoneyChanged", p)
umsg.Short(p:GetNetworkedInt("cash"))
umsg.End()
else
Msg("Incorrect number of arguments! gfc_givecash 'name' 'amount'")
end
end
end)
[/lua]

And the error is still "init.lua:40] bad key to string index (number expected, got string)". I am assuming it has to do with what you said about checking for the player, but how exactly would I do that?

Thank again for any help in advanced. Its nice to have such a good resource on facepunch.com

Pop this somewhere that your script will be able to find it (say at the top of the script) and then use local p = player.Get(args[1])
[lua]---
-- Gets a player by a part of their name, or their steamID, or their UniqueID, or their UserID.
-- Will provide the player with the shortest name that matches the key. That way a search for 'lex' will return 'Lexi' even if 'LeXiCaL1ty{GT}' is available.
-- @param id An ID to search for the player by.
-- @return A player if one is found, nil otherwise.
-- @author Lexi R
function player.Get(id)
local res, len, name, num, pname, lon;
name = string.lower(id);
id = string.upper(id);
num = tonumber(id);
for _,ply in pairs(player.GetAll()) do
pname = ply:Name():lower();
if ((num and (ply:UniqueID() == num or ply:UserID() == num)) or ply:SteamID() == id) then
return ply;
elseif (pname:find(name)) then
lon = pname:len();
if (res) then
if (lon < len) then
res = ply;
len = lon;
end
else
res = ply;
len = lon;
end
end
end
return res;
end[/lua]

Incidentally, you're not checking to see if the input arguments are valid. Try something like this
[lua]local p = player.Get(args[1])
local num = tonumber(args[2])

if not p then
ply:ChatPrint("Invalid player '" .. args[1] .. "'!")
return -- End the function early
elseif not num then
ply:ChatPrint("Invalid amount '" .. args[2] .. "'!")
return
end[/lua]

[zzaacckk]

[lua]
local p = args[1]
[/lua]

You are setting p equal to a string/number, then running entity only functions on it.

O... M... G... I cant thank you enough for your help. After reviewing the code snips, I see what lua was saying... Yet again it is so nice to have such a good resource here on facepunch.com. Thanks everyone.

[Crap-Head]

So in the last 3 hours, i've been doing everything to resolve this issue, tho i cannot seem to find a way to fix this.

Heres my code:

local SW,SH = ScrW(),ScrH()

local HealthText = "Healthy"
local HealthColor = Color(0,102,0,255)

-- Health
surface.SetFont("HUDText_Health_Scaled")
surface.SetTextColor(HealthColor)
local x,y = surface.GetTextSize(HealthText)
surface.SetTextPos(ScreenScale(25), SH-ScreenScale(12.5)-y*0.5)
surface.DrawText(HealthText)

Heres the error that repetitively gets spammed:
[gamemodes/testgm\gamemode\client\hud.lua:375] attempt to perform arithmetic on local 'y' (a nil value)(Hook: HUDPaint)
1. lua/includes/modules/hook.lua:106 (unknown)

Line 375 is "surface.SetTextPos(ScreenScale(25), SH-ScreenScale(12.5)-y*0.5)".

Please notice that this is from GMod 13.

Thank you in advance.

[Lexic]

When in doubt, put a print statement. Try shoving print(x, y) before the line which errors and see what it outputs.

[Ronon Dex]

What happened to Vector:Normalize(Vector) in GMod 13? It no longer works properly for me now.

Use before:
[lua]
local t = p:GetEyeTrace();
local cv = self.Entity:WorldToLocal(t.HitPos):Normalize();

local da = math.deg(math.acos(v:DotProduct(cv)/v:Length()));

[/lua]

It says it can't DotProduct cv because it equals nil where as it should be a vector.

EDIT:
So I have to just do
[lua]
local cv = self.Entity:WorldToLocal(t.HitPos)
cv:Normalize()
[/lua]

Now then?

[Pelly]

I've been trying to use the player classes in gmod 13 and on the wiki it says the following:
[QUOTE]

DEFINE_BASECLASS( "player_default" )

local PLAYER = {} 

--
-- See gamemodes/base/player_class/player_default.lua for all overridable variables
--
PLAYER.WalkSpeed 			= 200
PLAYER.RunSpeed				= 400


function PLAYER:Loadout()

	self.Player:RemoveAllAmmo()
	
	self.Player:GiveAmmo( 256,	"Pistol", 		true )
	self.Player:Give( "weapon_pistol" )

end

player_manager.RegisterClass( "player_custom", PLAYER, "player_default" )

These player class functions are usually housed in gamemode/player_class/ - and they do not get loaded automatically. You should load it in your shared.lua gamemode file. And they should be loaded in the right order - so that base classes get loaded before their children. [/QUOTE]

What does it mean about loading them and/or How would i go about loading them?

Thanks in advance.

It works the same way it always has. Normalize MODIFIES the vector, but doesn't return anything. GetNormalized/GetNormal return a vector, and don't modify the original.

I am working on a swep that will ragdoll a player when shot. Everything works perfectly except the ragdoll says "Owner: N/A" and can be claimed by another player. If the player then deletes that ragdolled player, the server crashes. I need to know how to set the ragdoll entity to owner: world by default or at least disable interaction with it.

This is the snip that dictates the ragdoll ness...
[lua]
local rag = ents.Create("prop_ragdoll")
rag:SetModel( plyTarget:GetModel() )
rag:SetPos( plyTargetPos )
rag:Spawn()
rag:Activate()
[/lua]

I am using SPP (Simple Prop Protection) on my server. Any help would be appreciated and thanks in advance :D

I think for setting owner this should work:
[lua]
rag:SetOwner(GetWorldEntity())

Hello, I'd like to know where I would put this to actually make it work, or if the code is just wrong, cause no one tells you where to put your HUD code after you make it...

function HUDHide( hud )

		if hud == v then
			return false
		end
	end
end
hook.Add( "HUDShouldDraw", "HUDHide", HUDHide)

	local person = LocalPlayer( )
	local Health = LocalPlayer( ):Health( )
	surface.CreateFont( "coolvetica",64,400,false,false,"tbsfont" )
	surface.SetTextColor( 255,255,255,255 )
	surface.SetTextPos( 34, (ScrH()/2)+(ScrH()/4) )
	surface.SetFont( "tbsfont" )
	surface.DrawText( "Health: "+Health )
end
