My code for a HUD isn't working

[TheFallen(TF2)]

[QUOTE=Jcw87;26439787]
Hang on, is this an external Lua interpreter? AddCSLuaFile doesn't exist anywhere other than gmod, so run it in gmod.[/QUOTE]

[url]http://en.wikipedia.org/wiki/SciTE[/url] That is what I used for coding the debugger found a few errors but most of the errors I found were in the console for gmod such as this recent one I found after I edited the code: [lua\autorun\init.lua:2] attempt to call global 'AddCSLua' (a nil value)

AddCSLua is not a function. You are looking for AddCSLuaFile. Did you read my post thoroughly?

Yes I did so I corrected the problem and now its not showing any errors relating to AddCSLuaFile however I did get this error: lua: HUDDistrict9.lua:4: attempt to index global 'surface' (a nil value)

surface is a client-side library. It has to be run client-side. Change the top of your file to look like this:
[lua]
if SERVER then AddCSLuaFile("filename.lua") return end
[/lua]

Okay, but do I include the directory or not?

You don't need to.

I checked the gmod wiki about this error here: lua: HUDDistrict9.lua:2: '<eof>' expected near 'end' and the gmod wiki has nothing about it, can anyone tell me what this means?

google the error, its a common one, it means your missing (or exceeding, forgot which) 1 or more "end"s

You are not using the correct number of 'end's. Load your script with notepad++, and pay close attention to the left margin. There will be buttons for "collapsing" your code. Pay attention to where the lines that extend from those buttons go. Example:

[img]http://img574.imageshack.us/img574/1396/notepadpp.png[/img]

Notice how the lines connect the beginning statement to the appropriate 'end'. Search your script for any irregularities with these lines.

Okay that error has been taken care of but now I'm getting another error: lua: HUDDistrict9.lua:5: attempt to index global 'surface' (a nil value)

Do I put function in front of it? Or Hook?

[Lord Ned]

Are you running this script on the client?

[editline]4th December 2010[/editline]

What color is the error? Is it blue or yellow when it pops up in the upper right?

I run it on the client for testing but this time the surface error didn't come up this time, but this did and it was blue:
[lua\autorun\init.lua:2] attempt to call global 'AddCSLua' (a nil value)
and when I tried to debug it in SciTE it came up with this red error: lua: HUDDistrict9.lua:4: attempt to index global 'surface' (a nil value)

So this is a big double wammy for me, because I have no clue why it is doing one thing in SciTE and another totally different thing in Garry's Mod.

Because in SciTE the lua debugger does not have garrysmod lua functions

here's a tip, don't use SciTE anymore for debugging.

You don't use anything, you enter your game, and look for errors which get printed in the console, simple huh?

put your entire code here again

but it should be
[lua] if SERVER then AddCSLua "init.lua" end[/lua]

although it could be because you named it init.lua, try naming it something else.

Its not named init.lua.

Any way here is the code:
[lua]if SERVER then AddCSLua ("cl_hud_remove.lua")
print("cl_hud_remove.lua loaded!")
end
surface.CreateFont ("D9 non-humans",54, 400, false, false, "Text32")

function MyCustonHUDPaint()
print ( "GM:HUDPaint() blah blah" )

local person = LocalPlayer()
print ("Player: "..tostring(person))
local Health = LocalPlayer(): Health()
print ("Health: "..tostring(helath))

surface.SetText( 255, 0, 0, 255 )
surface.SetTextPos( 34, ScrH()/2 + ScrH()/4 )
surface.SetFont("Text32")
surface.DrawText( Health )

end

hook.Add( "HUDPaint", "MyCustomHUDPaint", MyCustomHUDPaint)[/lua]

[Lord Ned]

Do this:

[lua]
if (SERVER) then
AddCSLuaFile( "test_hud.lua" )
end

if (CLIENT) then
function HideHudBits( name )
if ( name == "CHudHealth" or name == "CHudBattery") then
return false
end
end
hook.Add( "HUDShouldDraw", "HideHudBits", HideHudBits )

surface.CreateFont( "D9 non-humans", 54, 400, false, false, "D9NonHumans" )
hook.Add( "HUDPaint", "D9HudPaint", function()
local hudPlayer = LocalPlayer()
local hudHealth = hudPlayer:Health()

surface.SetTextColor( 255, 255, 255, 255 )
surface.SetTextPos ( 34, (ScrH()/2) + (ScrH()/4) )
surface.SetFont( "D9NonHumans" )
surface.DrawText( hudHealth )
end)
end
[/lua]

Then put that in "D9Hud.lua" inside your lua/autorun folder. It works, throws no errors, etc.

Which results in this:

[editline]4th December 2010[/editline]

Also the D9 Non-Humans font is worthless, you can't tell anything about it really. I tried making it bigger and giving it a drop shadow/outline to no avail..

then why is your error

[lua\autorun\[u][b]init.lua[/b][/u]:2

[TheFallen(TF2)]

Thanks for the help guys it finally works! I owe all of you for the help big time! But I have a few questions before this thread is locked:
1. How do I add boxes to go around the the health text?
2. How do I add a health bar?
3. And when I add armor do I add a separate function or not?

[Zephilinox]

Take a look at this thread: [url]http://www.facepunch.com/threads/1032991[/url]

Just make sure you draw the box first, and then draw the text over the box's position.

also take a look at this: [url]http://wiki.garrysmod.com/?title=Clientside:draw[/url]

this shows you how to make a health bar, and add text to it: [url]http://wiki.garrysmod.com/?title=Simple_HUD_Tut[/url]

And there were several spellings mistakes in the script you posted which would stop it from working, heres the fixed version:

[lua]
if SERVER then AddCSLuaFile ("cl_hud_remove.lua")
print("cl_hud_remove.lua loaded!")
end
surface.CreateFont ("D9 non-humans",54, 400, false, false, "Text32")

function MyCustomHUDPaint()
print ( "GM:HUDPaint() blah blah" )

local person = LocalPlayer()
print ("Player: "..tostring(person))
local health = LocalPlayer():Health()
print ("Health: "..tostring(health))

surface.SetText( 255, 0, 0, 255 )
surface.SetTextPos( 34, ScrH()/2 + ScrH()/4 )
surface.SetFont("Text32")
surface.DrawText( health )

end

hook.Add( "HUDPaint", "MyCustomHUDPaint", MyCustomHUDPaint)
[/lua]

1. Learn Lua
2. Learn Lua

However... Only since I still have the file open:
[lua]
if (SERVER) then
AddCSLuaFile( "test_hud.lua" )
end

if (CLIENT) then
function HideHudBits( name ) --This is run once, when the hud first tries to draw
if ( name == "CHudHealth" or name == "CHudBattery") then
return false
end
end
hook.Add( "HUDShouldDraw", "HideHudBits", HideHudBits )

surface.CreateFont( "D9 non-humans", 78, 400, true, false, "D9NonHumans", true, true )
hook.Add( "HUDPaint", "D9HudPaint", function() --This is run every frame. Anything that needs to get drawn can be added here
local hudPlayer = LocalPlayer()
local hudHealth = hudPlayer:Health()

local hudArmor = --What's it equal? Here's a hint, it's found here: [url]http://wiki.garrysmod.com/?title=Player[/url] It's also similar to "hudPlayer:Health()

--If we want to draw backgrounds, we have to do it before we draw the stuff ontop of it, or else it'd draw over soo..
--More stuff/information here: [url]http://wiki.garrysmod.com/?title=Surface[/url]
surface.SetDrawColor( 128, 128, 128, 255) --Set it's background to a generic grey
surface.DrawRect( x position, y position, width, height) --FILL THESE OUT

--DRAW THE FONTS ONTOP
surface.SetTextColor( 255, 255, 255, 255 )
surface.SetTextPos ( 34, (ScrH()/2) + (ScrH()/4) )
surface.SetFont( "D9NonHumans" )
surface.DrawText( hudHealth )

--Now do more surface commands. You've already set the color, and the font... So maybe if you just change the position and what text it should draw?
surface.SetTextPos --Fill this out
surface.DrawText( ) --What do we want to draw now, armor? We have a variable, maybe put that in here?
end)
end
[/lua]

[b]You'll probably want to use this over Zeph's just because it matches your other code and is written to be run on both the client/server without issues.[/b]

[TheFallen(TF2)]

You mean sort of like this:

[lua]if (SERVER) then
AddCSLuaFile( "cl_hud_remove.lua" )
end

if (CLIENT) then
function HideHudBits( name )
if ( name == "CHudHealth" or name == "CHudBattery") then
return false
end
end
hook.Add( "HUDShouldDraw", "HideHudBits", HideHudBits )

surface.CreateFont( "D9 non-humans", 100, 400, false, false, "D9NonHumans" )
hook.Add( "HUDPaint", "D9HudPaint", function()
local hudPlayer = LocalPlayer()
local hudHealth = hudPlayer:Health()

local hudArmor = hudPlayer:Armor()

surface.SetDrawColor( 128, 128, 128, 255)
surface.DrawRect( 1, 34, 25, 25 )

surface.SetTextColor( 255, 0, 0, 255 )
surface.SetTextPos ( 34, (ScrH()/2) + (ScrH()/4) )
surface.SetFont( "D9NonHumans" )
surface.DrawText( hudHealth )

surface.SetTextColor(255,0, 0, 255)
surface.SetTextPos(24 (ScrH()/2) + (ScrH()/4) )
surface.SetFont("D9NonHumans")
surface.DrawText( HudArmor )
end)
end
[/lua]

[Lord Ned]

Looks like it'd work, does it not?

Also the:
if (SERVER) then
AddCSLuaFile( "cl_hud_remove.lua" )
end

You don't need cl_hud_remove.lua anymore, I built it into the start of the if (CLIENT) section.

I had it downloading the hud itself, which I don't know if it's necessary, depends if you're using it as a gamemode or just an addon people can install.

I'm going to be using it in a remake of GoFish2 I'm planning on making which will have a menu that can enable custom HUDS.

Heres the code for the HUD so far btw:
[lua]function HideHudBits( name )

return false
end
end
hook.Add( "HUDShouldDraw", "HideHudBits", HideHudBits )

local hudArmor = hudPlayer:Armor()

surface.SetTextPos (24 (ScrH()/2) + (ScrH()/4) )
surface.SetFont ("D9NonHumans")
surface.DrawText ( HudArmor )
end)
end

It stopped working and I don't know why.

[Lord Ned]

You have to tell us what's wrong, we're not mind readers.

What error, what line, what message, etc. Look in your console and scroll up to find one.

I don't understand what that means I checked the wiki and it didn't say what the error was, plus the game has reverted back to using the HL2 HUD.
