HUD Code Makes Me Crash

[Zmaster]

I wanted to start working with HUDs yesterday, so I found a video on YouTube for it and then fixed the code he showed (His code was outdated and produced errors)

After making it work with GM13, I realized whenever I was on my server running the code for a few minutes, I would crash out of GMod with no errors or anything

I get no errors on the code and my game shows no errors when I crash
My GMod will just suddenly close

I'm sure this code is making me crash, because when I moved it to another folder where the code wouldn't run, I stopped crashing

Code: Lua

1. //include( "shared.lua" )
2.  
3. hook.Add( "HUDShouldDraw", "hidethehud", function( name )
4.         if (name == "CHudHealth" or name == "CHudBattery" or name == "CHudAmmo") then return false end end )
5.  
6. function PaintZeeHud()
7.         local ply = LocalPlayer()
8.         local HP = ply:Health()
9.         local ARM = ply:Armor()
10.         local NewScrH = (ScrH() - 50 )
11.        
12.         draw.RoundedBox( 10, 10, NewScrH - 30, 75, 75, Color( 87, 81, 81, 255 ) )
13.         surface.CreateFont( "ZeeFont", {
14.         font = "ScoreboardText",
15.         size = 40,
16.         weight = 255,
17.         antialias = false,
18.         underline = false,
19.         italic = false,
20.         })
21.         surface.SetTextColor( 0, 0, 255, 255 )
22.         if (ply:Health() == 100) then
23.                 surface.SetTextPos( 20, NewScrH - 14)
24.         elseif (ply:Health() == 0) then
25.                 surface.SetTextPos( 39, NewScrH - 14 )
26.         else
27.                 surface.SetTextPos( 30, NewScrH - 14 )
28.         end
29.         surface.SetFont( "ZeeFont" )
30.         surface.DrawText( HP )
31. end
32. hook.Add( "HUDPaint", "PaintZeeHUDHook", PaintZeeHud )

Does anyone know what I did wrong?
Line 1 is commented out because I didn't create a shared.lua file yet

I didn't know if that was a default font or not so I went with Arial. The HUD worked for me after I changed the function name and removed a hook:

Code: Lua

1. //include( "shared.lua" )
2.  
3. hook.Add( "HUDShouldDraw", "hidethehud", function( name )
4.         if (name == "CHudHealth" or name == "CHudBattery" or name == "CHudAmmo") then return false end end )
5.  
6. function GM:HUDPaint()
7.         local ply = LocalPlayer()
8.         local HP = ply:Health()
9.         local ARM = ply:Armor()
10.         local NewScrH = (ScrH() - 50 )
11.  
12.         draw.RoundedBox( 10, 10, NewScrH - 30, 75, 75, Color( 87, 81, 81, 255 ) )
13.         surface.CreateFont( "ZeeFont", {
14.         font = "Arial",
15.         size = 40,
16.         weight = 255,
17.         antialias = false,
18.         underline = false,
19.         italic = false,
20.         })
21.         surface.SetTextColor( 0, 0, 255, 255 )
22.         if (ply:Health() == 100) then
23.                 surface.SetTextPos( 20, NewScrH - 14)
24.         elseif (ply:Health() == 0) then
25.                 surface.SetTextPos( 39, NewScrH - 14 )
26.         else
27.                 surface.SetTextPos( 30, NewScrH - 14 )
28.         end
29.         surface.SetFont( "ZeeFont" )
30.         surface.DrawText( HP )
31. end

Getting this error on that code
Why would GM: not be recognized?

[JamminR]

Ouch Zmaster, learn to copy/paste text from console
I've little to no experience with gamemode, but probably cause GM has to be registered in some way.
Had some oddity like that with a script many years ago.
Had to go from GM to "gamemode" or something like that.
GAMEMODE perhaps.
SOrry, don't fully remember.

[Zmaster]

Okay...
Changed GM to GAMEMODE and no longer got an error

However, after a minute or two of severe lag on my computer (was getting this lag before I came here for help), GMod will crash.

Again, no errors
I just start lagging a ton, then my game closes and the lag stops

I've tried reinstalling my game and removing unnecessary addons and even verified my game cache, but the problem is still occuring

[JamminR]

Did you try "Dog's" code, not using a custom font?
If not, try that.
If that works, investigate to see if a font can/should be created outside of HUDPaint, then used within it.
I would imagine creating a font every frame draw, even the same one, might not be the proper way to do it.
(Again, I'm inexperienced here...I've never worked with GUI in Gmod)

[Dog]

Okay, so a non-laggy code I have got:

Code: Lua

1. include( "shared.lua" )
2.  
3. hook.Add( "HUDShouldDraw", "hidethehud", function( name )
4.         if (name == "CHudHealth" or name == "CHudBattery" or name == "CHudAmmo") then return false end end )
5.  
6. surface.CreateFont( "ZeeFont", {
7.         font = "Arial",
8.         size = 40,
9.         weight = 255,
10.         antialias = false,
11.         underline = false,
12.         italic = false,
13.         })
14.  
15. function GAMEMODE:HUDPaint()
16.         local ply = LocalPlayer()
17.         local HP = ply:Health()
18.         local ARM = ply:Armor()
19.         local NewScrH = (ScrH() - 50 )
20.  
21.         draw.RoundedBox( 10, 10, NewScrH - 30, 75, 75, Color( 87, 81, 81, 255 ) )
22.         surface.SetTextColor( 0, 0, 255, 255 )
23.         if (ply:Health() == 100) then
24.                 surface.SetTextPos( 20, NewScrH - 14)
25.         elseif (ply:Health() == 0) then
26.                 surface.SetTextPos( 39, NewScrH - 14 )
27.         else
28.                 surface.SetTextPos( 30, NewScrH - 14 )
29.         end
30.         surface.SetFont( "ZeeFont" )
31.         surface.DrawText( HP )
32. end
33.  

To import a font you can just make a simple addon(that's how I did it) and then it'll download to the client.

Code: Lua

1. if SERVER then
2.         resource.AddSingleFile("resource/fonts/<font file name here>.ttf")
3. end

[JamminR]

So it does seem like creating a font every frame is what is causing the issue.
My educated guessing sometimes works.

[Zmaster]

haha

I didn't even think about that, but now that you mention it, it would make sense to make the font outside of the GAMEMODE:HudPaint

Thanks for the help, JamminR and Dog
