Is there a function that i can use to show a tip text when i put the mouse over an image?

[vontiagaming]

How would i make it so a chat command only works when looking at an entity? Thanks.

If you don't care about the range look into this..

[QUOTE=Mornedil;47741528]I'm also pretty new at lua, but have some experience with game programming before :P.

As for controlling the player's angles with WASD, you should look into [URL="http://wiki.garrysmod.com/page/Player/SetEyeAngles"]SetEyeAngles[/URL].

To turn movement keys into numeric variables, you can do the following:
(This can be very useful in order to use those key presses to calculate the eye angle vectors)

--ply should be the player entity
local w = ply:KeyDown(IN_FORWARD) and 1 or 0		 --set variable to 1 if KeyDown is true, or set it to 0 if KeyDown is false.
local s = ply:KeyDown(IN_BACK) and 1 or 0
local a = ply:KeyDown(IN_MOVELEFT) and 1 or 0
local d = ply:KeyDown(IN_MOVERIGHT) and 1 or 0

I just learned about how to do that, so.. if it gives an error, enclose within ( ), like:

local w = ( ply:KeyDown(IN_FORWARD) and 1 or 0 )

KeyDown returns either true or false depending on if you press the key or not.
so in the above code, the variables w, a, s and d will be set to 1 if you're holding the key, and 0 if you're not.

I'm not sure how to make the player always walk forward with WASD, instead of strafing or moving backwards.

As for checking for walls to prevent players from walking up/down in corridors, maybe [URL="http://wiki.garrysmod.com/page/util/TraceLine"]TraceLine[/URL] ?[/QUOTE]

Yes! You definitely got me set on the right path, I think. I'm going to be working on this before work tomorrow. Thank you so much for the suggestions; you rock!

Am I missing something with SetNWBool? It doesn't seem to be syncing to the client.

Serverside:

> for k,v in pairs( player.GetAll() ) do v:SetNWBool("test", true ) end
> for k,v in pairs( player.GetAll() ) do print(v:GetNWBool("test")) end
true

Clientside:

] lua_run_cl for k,v in pairs( player.GetAll() ) do print( v:GetNWBool("test") ) end
false

[Mornedil]

Quetsion about sending models/textures to the client:

The official [URL="https://github.com/adamdburton/pointshop-extras"]pointshop extras[/URL] addon has a script which sends everything the specified folders to the client.

But, I've noticed that on lots of servers that use the pointshop, these files get sent [B]every time[/B] the player joins.

Can the script be adjusted to first check if the client has the files, and only download/update them if the client's files doesn't match up with the server's files?

-- Add model and material folders here as required
-- WARNING: THIS WILL TELL CLIENTS TO DOWNLOAD EVERYTHING POSSIBLE FROM THESE FOLDERS
-- I RECOMMEND YOU BE SELECTIVE

local models = {
	'astronauthelmet',
	'cakehat',
	'duncehat',
	'fish',
	'gmod_tower',
	'lordvipes/mariohat',
	'props/cs_office',
	'props/de_tides',
	'santa',
	'vikinghelmet'
}

local materials = {
	'models/astronauthelmet',
	'models/cakehat',
	'models/duncehat',
	'models/gmod_tower',
	'models/sam',
	'models/santa',

	'models/samus',
	'models/fish',
	'models/props/cs_office',
	'models/props/de_tides',
	'psicons'
}

-- end

function resource.AddDir(dir)
	local f, d = file.Find(dir .. '/*', 'GAME')
	
	for k, v in pairs(f) do
		resource.AddSingleFile(dir .. '/' .. v)
	end
	
	for k, v in pairs(d) do
		resource.AddDir(dir .. '/' .. v)
	end
end

for _, mf in pairs(models) do
	resource.AddDir('models/' .. mf)
end

for _, mf in pairs(materials) do
	resource.AddDir('materials/' .. mf)
end

[zerf]

You could network and compare the util.CRC or file.Time() date of the file if you want exact matches (probably not worth tbh), otherwise file.Exists() them. Simple if statement inside the AddSingleFile for loop.

[wyozi]

Bigger problem seems to be usage of serverdl instead of fastdl. If you use fastdl that should not happen.

Anyone got any decent ways of drawing a radial menu, my maths sucks ass :(

Guess it would be similar to how CSGO's is drawn

[Tomelyr]

[lua]local places = 360 / #thingstodraw
do
local x0, y0 = 0, 0
local px, py = ScrW() / 2, ScrH() / 2
local sizex, sizey = ScrH() / 2.8, ScrH() / 2.8
for i = 0, 360, places do
i = i + 180
local x1 = math.sin( math.rad( i ) ) * sizex
local y1 = math.cos( math.rad( i ) ) * sizey
if ( i - 180 ) > 0 then
local index = math.Round( ( i - 180 ) / places )
surface.SetDrawColor( 255, 255, 255, 255)
surface.DrawRect( x0 + px - 60, y0 + py, 120, 45 )
end

x0 = x1
y0 = y1
end
end

some old code i had lying arround here. Dunno who make it tbh, but kudos to him.

[Mornedil]

I decided to just make a workshop addon with all the models and put it as a force download.

[DonnieLewis]

What exactly is the replacement for the old

self:DrawEntityOutline( 1.0 )

code?

[WalkingZombie]

How can I make a sort of "bubble" around a model? That is, create a clientside model that's the same, except with bones inflated, that floats around the original model, and apply a texture to it?

I pretty much described what I need to do, I think, but I honestly have no idea how I could do that.

I need to ask again if someone could give me any pointers regarding DLabels height.
Using SetWrap( true ) results in the text automatically jumping down a line - great, but how am I supposed to know how tall the text is? Using GetTall() just returns the one-line height.

This is the solution I have right now but it doesn't work properly, for example a 3 line tall DLabel gives another amount of padding to the next DLabel than if it was a 1 or 2 lines, while I just want 2 lines in everyone:

		for i, v in pairs( Laws.Default ) do
			text[ count ] = vgui.Create( "DLabel", holder );
			text[ count ]:SetPos( 0, padding );
			text[ count ]:SetColor( Color( 255, 255, 255, 255 ) );
			text[ count ]:SetText( v );
			text[ count ]:SetWide( holder:GetWide() - 10 );
			text[ count ]:SetWrap( true );
			text[ count ]:SetAutoStretchVertical( true );
			
			w, h = surface.GetTextSize( text[ count ]:GetText() );
			mathc = math.Round( text[ count ]:GetWide() / ( holder:GetWide() - 10 ), 0 );
			
			padding = padding + h + h * ( mathc + 1 );
				
			count = count + 1;
		end

I tried looking for \n and for each of those add a certain amount to padding but it seems like there's no \ns :/

Any reason you aren't using docking ? From the way they are laid out each one could be docked to the top and they should flow down easy enough.

I am trying to make a script that keep the ammo the same for a player when they die. The weapons are FA:S.
[lua]
for k,v in pairs( savedammo ) do

local split = string.Explode("/", v )
print(split[1].." " ..split[2])
target_ply:SetAmmo(split[1],split[2])

end
[/lua]

I am getting all of their guns ammo by creating a loop with GetWeapons then creating this variable
[lua] local ammo = ply:GetAmmoCount( v:GetPrimaryAmmoType() ).. "/" ..v:GetPrimaryAmmoType()
[/lua]
and putting it into the table savedammo.

It should work, because the split[1] and split[2] are the correct values but it never sets the ammo to that..The values that it gives for that print are
[lua]
120 48
[/lua]

[DEL]Trying to modify weapon stats server-side (I know I have to update the values client-side) by:

hook.Add("OnEntityCreated", "SWSOnEntityCreate", function(ent)
	if ent:IsWeapon() then
		ent.Primary.Damage = 5
	end
end)

However it does not work, resulting in Primary being nil. Printing ent results in the weapon but no way of modifying any stats. Any help?[/DEL]

Got it. It was due to Primary not being set until next frame.

Trying to implement a team limit on a shitty game mode I'm making.

The function I made. I know its equal to 0, I just did that to test if this would work at all.

local function TeamLimit(ply)
   if team.NumPlayers(2) == 0 then
   ply:ChatPrint("Team is full")
   return false
   end
end

Hook I made to hook onto the function to control team switching

hook.Add("TeamSwitch","Limit",TeamLimit)

Team Switching function

local function TeamSwitch(ply,text)
    text = string.lower(text)
	if (string.sub(text,1) == "!juggernaut") then
	
	   ply:SetTeam(2)
	   ply:Spawn()
	   ply:StripWeapons()
	   ply:Give("weapon_crowbar")
	   ply:SetWalkSpeed(50)
	   ply:SetRunSpeed(200)
	   
	end
	
end

I'm new to lua, so bare with me. Any help is appreciated.

You can't hook a function of your own, what you can do is hook into this:
[url]http://wiki.garrysmod.com/page/GM/PlayerCanJoinTeam[/url]
inside the hook, you check:
how many is in the team(your TeamLimit function)
if TeamLimit returns true(he can join) then run your TeamSwitch function

What you can do is also hook.Call = making your own hook but that seems unecessary

hook.Add( "PlayerCanjoinTeam", "ofgsdhodhjf", function( ply, team )

    // team is the number of your team
    if( #team.GetPlayers( team ) > #team.GetPlayers( other team(s) ) or just == 2 ) then
        return false; // team is full
    else
        return true; // he can join team
    end

end );

hook.Add( "PlayerSpawn", "seoesgko", function( ply )

    for i, v in pairs( exampleLoadoutTable[ ply:Team() ] ) do
            ply:Give( v );
    end

end );

I'm trying to create a duplicate model of another... I want to perfectly mimic the bone positions / angles, but I don't know how to do that!

How can I word that better? How could I replicate the bone pose of a model, and apply it to another? Model [B]A[/B] was raising its hands while kicking a ball, I want model [B]B[/B] to look the same.

[editline]20th May 2015[/editline]

Let's see if I can answer my own question. Correct me if I'm wrong, but I would have to use [B]GetBoneMatrix[/B] for each and every bone on model [B]A[/B], and [B]SetBoneMatrix[/B] on the bones of model [B]B[/B]? But is that efficient?

you probably need those and then get the bone from model 2 and SetPos/SetAngles like the bone for model 1

In whatever way your team changing is set up, once a player attempts to switch team, that hook "PlayerCanJoinTeam" will be run. If you return false, the player can't change team, if you return true, the player can change team.
