[QUOTE=PortalGod;47284503]if you're using the default fonts, you'll have to remake them (you can find the source for most of them [url=https://github.com/garrynewman/garrysmod/search?utf8=%E2%9C%93&q=createfont&type=Code]here[/url])[/QUOTE]

I'm using a custom font :P

[PortalGod]

then just use ScrW()/ScrH()/ScreenScale() for the size argument like you would use them in a HUD or something

[Whiterabbit]

[QUOTE=GoldTrigger;47284260]Anyone know how to scale fonts according to screen size? ._. Left this out of my hud woops[/QUOTE]

Use [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/Global/ScreenScale]Global.ScreenScale[/url] when defining your font size.

EDIT: Ninja'd

[hexpunK]

Is it possible to set the view and world models on a weapon on the fly? I've played around with the entity:SetModel() and switching the SWEP structure values to the new one as they seemed like obvious places to start. But now I'm totally stuck as to how to do this.

Unless there's some function I've missed, because I expect the view and world models are tied to the player more than the weapon.

Is it possible to create animations in Lua? Things like adding a dance animation or prone animation to a player or even new weapon animations.

[MysteryPancake]

Why does IsOnGround not return true with any props touching the ground? There isn't a 'IfTouching', is there, or do I have to use some sort of trace?

concommand.Add("ongroundtest", function()
for k, v in pairs( ents.GetAll() ) do
if not ( v:GetModel() == nil ) then
print("Model:",v:GetModel(),"On Ground?",v:IsOnGround() )
end
end
end)

[G4MB!T]

IsOnGround has been broken for ages. You can do a hull trace.

[MysteryPancake]

Okay, thanks

I've never used it myself but I know it's designed for use with fonts. It returns a number based on your screen size and the number you give it. Just play with the number you give it until you have it looking exactly as it currently does, then check it on a different resolution.

And yeah people use "ninja'd" to mean someone posted the answer (fast like a ninja) while they were still typing.

I can't give a complete answer but when I played with having the player equip one actual weapon and then change its hold type and model through code, I had to use net messages to tell all clients to apply the same changes. Also need to network it to newly joined players otherwise they see whatever is the default for that swep (depending on your code I guess)

Is there a way to disable player spawning?

This code used to work perfectly fine before the update, it would show names, health etc above NPC's.
Now it does nothing at all and give no errors.

I'm having problems setting and getting $nodecal on materials. I made a function to print the value of a field in each type:

[lua]
function printMatData(mat, field)
print("Checking '$" .. field .. "' on " .. mat);
local mat = Material(mat);
print(mat:GetFloat("$" .. field));
print(mat:GetInt("$" .. field));
print(mat:GetMatrix("$" .. field));
print(mat:GetString("$" .. field));
print(mat:GetTexture("$" .. field));
print(mat:GetVector("$" .. field));
print();
end

printMatData("models/tdmcars/shared/skin", "nodecal");
printMatData("models/tdmcars/shared/skin1", "nodecal");
[/lua]

Here is the result:
[t]http://i.imgur.com/8INqWXp.png[/t]

And here is skin.vmt (skin1.vmt has "$nodecal" "1" as well):

"VertexlitGeneric"
{
	"$basetexturetransform" "center .5 .5 scale 80 80 rotate 0 translate 0 0"
	"$basetexture" "models/tdmcars/shared/skin"
	"$bumpmap" "models/tdmcars/shared/skin_normal"
	"$nodecal" "1"
	"$phong" 1
	"$phongexponent" 5
	"$phongboost"	2
	"$phongfresnelranges" "[1 1 1]"
	"$rimlight" 1
	"$rimlightboost" 0.5
	"$envmap" "env_cubemap"
	"$envmaptint" "[0.07 0.07 0.07]"
	"$normalmapalphaenvmapmask" 1
	"$phongfix" "{1 1 1}"
	Proxies
	{
		Equals
		{
			srcVar1	$color
			resultVar	$phongtint
		}
		Add
		{
			srcVar1 $phongfix
			srcVar2 $phongtint
			resultVar $phongtint
		}
	}
}

Any idea why its not printing? I cant mat:SetUndefined("$nodecal") either because it doesnt do anything.

Add a bunch of print statements to see where the code stops running at.

I really want to learn lua and I'm trying to use the gmod wiki to learn how. I did the intro, variable, and operator tutorials but I don't know where to go from there, anyone have any ideas on where to go next?

I don't particularly have a problem networking one more thing haha, I'm already networking a few values as is, one more int can't hurt. Changing holdtypes was quite nice and straightforward, the model switching however is still totally stumping me. I suppose I could not draw the model as you normally would and render a replacement instead, assuming you can merge these things via bones, kinda how the GM13 hands work.

Think of a small script, something simple but one that doesn't have a tutorial on the wiki. Maybe a thing that counts your deaths and throws progressively worse insults at you through the chat?

It should help you understand the applications of control structures, and you could work some data structure work into that to make it extend-able (like a table of insults to randomly choose from).

Fixed the model issue! The viewmodel just gets set in the PreDrawViewModel hook;
[lua]
hook.Add("PreDrawViewModel" , "LocalMorphLaser", function(viewM, ply, wep)

...
viewM:SetModel(modes[curMode].v_model)
...
end
[/lua]
The world model is just set in the SWEP:DrawWorldModel hook;
[lua]
function SWEP:DrawWorldModel()

self:SetModel(modes[self:GetCurMode()].w_model)
self:DrawModel()
end
[/lua]

However the viewmodels don't agree with things like reload animations or anything actually useful like that. Interestingly firing animations will work fine.

The Garry's Mod wiki is not for learning Lua, it is there to provide documentation for the API thats Garry's Mod provides. You should really consult [url=http://www.lua.org/manual/5.2/]this[/url].

It should check on each touch if all the ingredients are around it, and if so, delete them all and itself. What is wrong here? It only deletes the one it touches, and itself.

Does anyone know why entities that have never been in your line of sight are invalid? I send every players' entities using the net library and some are invalid when they are too far on the map.
