How do I change a DrawHUD texture?

[Aarone2004]

I'm trying to change a DrawHUD texture by changing the actual texture and then recalling self.DrawHud()

This is the code:

[LUA]
local ourMat = Material( "models/wireframe" ) -- Calling Material() every frame is quite expensive

function SWEP:DrawHUD()
surface.SetDrawColor( 255, 255, 255, 255 )
surface.SetMaterial( ourMat ) -- If you use Material, cache it!
surface.DrawTexturedRect( 0, 0, 256, 256 )
end

function SWEP:Reload()

print(ourMat)

ourMat = "decals/decalgraffiti024a"

print(ourMat)
self.DrawHUD()
/*
self:DefaultReload(ACT_VM_RELOAD)
return true
*/

end
[/LUA]

What do? :ohno:

Edit:
Error is:

[ERROR] addons/santa/lua/weapons/joyofpainting.lua:596: attempt to index global 'surface' (a nil value)

It's all wrong.

First of all, type of your variable "ourMat" is IMaterial, and in your reload function you set it to string.
Secondly, you are
1) Trying to call SWEP.DrawHUD manually for some reason ( don't, its called for you every fram )
2) Trying to call it in a non rendering hook ( it won't work, surface functions only work in 2 rendering context )
3) Also trying to call it ON THE SERVER ( server doesn't do rendering, which is why you are getting that error
4) Please read the wiki page for SWEP.Reload. IT WILL NOT BE CALLED ON CLIENT IN SINGLE PLAYER!

So where do I put the texture change? On key press or what? :ohno: instant halp pls

Robotboy already clearly explained what to do. Nobody's going to give you instant help if you can't even be bothered doing anything people tell you to do.

Yea I'm tryna fix it
This is my current code but I believe it's also serverside :\ (givin me the same error)

hook.Add( "KeyPress", "keypress-changegrafitti", function( LocalPlayer, IN_RELOAD )
		if ( key == IN_RELOAD ) then
			    ourMat = Material ( "decals/decalgraffiti024a" )
		end
	end )

How do I make a clientside keypress? :ohno:

If you're trying to call a clientside function on KeyPress just have KeyPress do a net.Start and net.Send() to the client and on the client do net.Receive. Don't forget to util.AddNetworkString("String") on the server before all of that.

Can you better explain what you're trying to do. I think I'm missing it.

If I remember correctly there's a way to get SWEP functions like Reload to run on the client even if they don't by default... I'll see if I can find it

[URL="http://wiki.garrysmod.com/page/Weapon/CallOnClient"]Yeah, here it is.[/URL] I'll try and make an example

[editline]11th July 2016[/editline]

Try this:

if CLIENT then

	local ourMat = Material( "models/wireframe" )

	function SWEP:DrawHUD()
		surface.SetDrawColor( 255, 255, 255, 255 )
		surface.SetMaterial( ourMat )
		surface.DrawTexturedRect( 0, 0, 256, 256 )
	end
	
	function SWEP:Reload()
		ourMat = Material( "decals/decalgraffiti024a" )
	end
	
end

if SERVER then

	function SWEP:Reload()
		self:CallOnClient( "Reload" ) -- Run the reload function clientside
	end

end

No clue if it works though.
