Hud Help

[WarJunky]

So im just startin off in the lua coding world. Im trying to create a simple hud using this tutorial.

[url]http://wiki.garrysmod.com/?title=Creating_a_HUD[/url]

And i cant seem to get it to work! I have my lua in the cl_init.lua file and i dont even get any errors! Heres the code im working with

good_hud = { };
 
local function clr( color ) return color.r, color.g, color.b, color.a; end
 
function good_hud:PaintBar( x, y, w, h, colors, value )
 
    self:PaintPanel( x, y, w, h, colors );
 
    x = x + 1; y = y + 1;
    w = w - 2; h = h - 2;
 
    local width = w * math.Clamp( value, 0, 1 );
    local shade = 4;
 
    surface.SetDrawColor( clr( colors.shade ) );
    surface.DrawRect( x, y, width, shade );
 
    surface.SetDrawColor( clr( colors.fill ) );
    surface.DrawRect( x, y + shade, width, h - shade );
 
end
 
function good_hud:PaintPanel( x, y, w, h, colors )
 
    surface.SetDrawColor( clr( colors.border ) );
    surface.DrawOutlinedRect( x, y, w, h );
 
    x = x + 1; y = y + 1;
    w = w - 2; h = h - 2;
 
    surface.SetDrawColor( clr( colors.background ) );
    surface.DrawRect( x, y, w, h );
 
end
 
function good_hud:PaintText( x, y, text, font, colors )
 
    surface.SetFont( font );
 
    surface.SetTextPos( x + 1, y + 1 );
    surface.SetTextColor( clr( colors.shadow ) );
    surface.DrawText( text );
 
    surface.SetTextPos( x, y );
    surface.SetTextColor( clr( colors.text ) );
    surface.DrawText( text );
 
end

Plz help a noob lol

Nobody knows what my problem is??

Check your console for errors.

Also you can do lua_openscript_cl <path to file> in the console, and it will run the file and you will see any errors immediately below it.

There are no errors, its wierd, i have no idea what is wrong, i even copied the script just like it was on the tutorial and its not working

Here:

[lua]
good_hud = { };

local function clr( color ) return color.r, color.g, color.b, color.a; end

function good_hud:PaintBar( x, y, w, h, colors, value )

self:PaintPanel( x, y, w, h, colors );

x = x + 1; y = y + 1;
w = w - 2; h = h - 2;

local width = w * math.Clamp( value, 0, 1 );
local shade = 4;

surface.SetDrawColor( clr( colors.shade ) );
surface.DrawRect( x, y, width, shade );

surface.SetDrawColor( clr( colors.fill ) );
surface.DrawRect( x, y + shade, width, h - shade );

end

function good_hud:PaintPanel( x, y, w, h, colors )

surface.SetDrawColor( clr( colors.border ) );
surface.DrawOutlinedRect( x, y, w, h );

x = x + 1; y = y + 1;
w = w - 2; h = h - 2;

surface.SetDrawColor( clr( colors.background ) );
surface.DrawRect( x, y, w, h );

end

function good_hud:PaintText( x, y, text, font, colors )

surface.SetFont( font );

surface.SetTextPos( x + 1, y + 1 );
surface.SetTextColor( clr( colors.shadow ) );
surface.DrawText( text );

surface.SetTextPos( x, y );
surface.SetTextColor( clr( colors.text ) );
surface.DrawText( text );

end

function good_hud:TextSize( text, font )

surface.SetFont( font );
return surface.GetTextSize( text );

end

local vars =

}

};

local function HUDPaint( )

client = client or LocalPlayer( ); -- set a shortcut to the client
if( !client:Alive( ) ) then return; end -- don't draw if the client is dead

local _, th = good_hud:TextSize( "TEXT", vars.font ); -- get text size( height in this case )

local i = 2; -- shortcut to how many items( bars + text ) we have

local width = vars.width * ScrW( ); -- calculate width
local bar_width = width - ( vars.padding * i ); -- calculate bar width and element height
local height = ( vars.padding * i ) + ( th * i ) + ( vars.text_spacing * i ) + ( vars.bar_height * i ) + vars.bar_spacing;

local x = vars.margin; -- get x position of element
local y = ScrH( ) - vars.margin - height; -- get y position of element

local cx = x + vars.padding; -- get x and y of contents
local cy = y + vars.padding;

good_hud:PaintPanel( x, y, width, height, colors.background ); -- paint the background panel

local by = th + vars.text_spacing; -- calc text position

local text = string.format( "Health: %iHP", client:Health( ) ); -- get health text
good_hud:PaintText( cx, cy, text, vars.font, colors.text ); -- paint health text and health bar
good_hud:PaintBar( cx, cy + by, bar_width, vars.bar_height, colors.health_bar, client:Health( ) / 100 );

by = by + vars.bar_height + vars.bar_spacing; -- increment text position

local text = string.format( "Suit: %iSP", client:Armor( ) ); -- get suit text
good_hud:PaintText( cx, cy + by, text, vars.font, colors.text ); -- paint suit text and suit bar
good_hud:PaintBar( cx, cy + by + th + vars.text_spacing, bar_width, vars.bar_height, colors.suit_bar, client:Armor( ) / 100 );

end
hook.Add( "HUDPaint", "PaintOurHud", HUDPaint );

Good luck.

You shouldnt start coding by doing a HUD. GUI programing is one the difficulest thing to do in gmod, especially when you start coding. You should start by doing SWeps and SEnts.

[CowThing]

I disagree Bilbasio. The first script I ever made was a GUI, it's a lot easier to understand than SWeps and SEnts.

I disagree with Bilbasio too. GUI's are pretty easy to make.

[NullPoint]

It is easy to create a GUI, It takes a little more effort to make it well.

[charozoid]

Null, thanks for correcting me, and by meaning a GUI, I was meaning coding a HUD. Coding a HUD is for me one of the difficulest thing to do. As you said it takes more times, but it takes alot more knowledge.

[WarJunky]

thanks for all the help guys, if anyone has any tips for a starter lua let me know plz

Thanks again
