Custom Deathrun HUD

Sup guys, I was looking over the interweb(Google) searching for a custom HUD for my server.

I found this code on a webpage but unfortunately the page didn’t have any instructions on where to place it
I figured it would go somewhere in this directory: “garrysmod\gamemodes\deathrun\gamemode” but I couldn’t find much
that matched, I was wondering if anyone knew where I would put this.


local vel = math.Round( LocalPlayer():GetVelocity():Length2D() )

draw.RoundedBox( 0, 5, ScrH() - 35, 250, 30, Color( 0, 0, 0, 200 ) )
draw.RoundedBox( 0, 5, ScrH() - 35, math.Clamp( vel, 0, 1000 ) * 0.25, 30, Color( 0, 0, 255, 255 ) )
