I believe | is a bitwise operator

[url]http://wiki.garrysmod.com/page/Libraries/bit[/url]

You need something from there but unfortunately I don't know which function (one of the ors?), sorry!

Try [b][url=http://wiki.garrysmod.com/page/Libraries/bit/bor]Libraries/bit/bor[img]http://wiki.garrysmod.com/favicon.ico[/img][/url][/b] though

[Lily]

You should just be able to use + instead, even though its a bad practice and breaks down if two flags overlap

[editline]3rd November 2012[/editline]

Alternativly the non-hacky way is
[lua]self:CapabilitiesAdd(bit.bor(CAP_MOVE_GROUND, CAP_ANIMATEDFACE, CAP_TURN_HEAD, CAP_USE_SHOT_REGULATOR, CAP_USE, CAP_WEAPON_RANGE_ATTACK1, CAP_USE_WEAPONS, CAP_MOVE_SHOOT, CAP_WEAPON_RANGE_ATTACK2, CAP_WEAPON_MELEE_ATTACK1, CAP_WEAPON_MELEE_ATTACK2, CAP_INNATE_RANGE_ATTACK1, CAP_INNATE_RANGE_ATTACK2, CAP_INNATE_MELEE_ATTACK1, CAP_INNATE_MELEE_ATTACK2))[/lua]

Did the latest update break ShouldCollide?

This shit isn't working:

return true

end
hook.Add("ShouldCollide", "ShouldCollideWithPlayer", ShouldCollideWithPlayer)

And it worked last update. :<

[Crap-Head]

Having some issues with GetModelScale and SetModelScale in GMod 13.

So i'm fully aware of the changes for SetModelScale in GMod 13, when scaling a Vector you need to use the Matrix thing. This works okay to being with:

[lua]
local scale = Vector( 0.3, 0.3, 0.3 )
local mat = Matrix()
mat:Scale( scale )
entity.EnableMatrix( "RenderMultiply", mat )
[/lua]

Now when i want to enlarger my prop by a bit from time to time, i want to use GetModelScale + a vector. This does not work like it used to.

[lua]
local scale = self:GetModelScale() + Vector( .05, .05, .05 )
local mat = Matrix()
mat:Scale( scale )
self:EnableMatrix( "RenderMultiply", mat )
[/lua]

It says for this line "local scale = self:GetModelScale() + Vector( .05, .05, .05 )":
bad arguement to #2 to '__add' (Vector expected, got number)

Apparently its the GetModelScale() that returns a number. Does anybody know how i would get around to fixing this issue?

Thank you.

[MDave]

GetModelScale now returns a number, what you used in SetModelScale. Store the matrix on the entity, and change that, since EnableMatrix does not provide any way to read the set matrix.

I guess I'm doing timers right now, but I found this error through one being called.

[ERROR] addons/warmelons/lua/autorun/server/wmrtscommands.lua:223: attempt to index local 'ply' (a nil value)
  1. unknown - addons/warmelons/lua/autorun/server/wmrtscommands.lua:223

Timer Failed! [Simple][@addons/warmelons/lua/autorun/server/wmrtscommands.lua (line 202)]

Right now, I want to address line 202:

	timer.Simple(2, WMInitialJoin)

The function follows right after and is only called when a player joins the game

function WMInitialJoin(ply)
	for i=1,6 do  
	local teammemcount = 0
	local colors = {}
	colors[0] = "admin"
	colors[1] = "red"
	colors[2] = "blue"
	colors[3] = "green"
	colors[4] = "yellow"
	colors[5] = "magenta"
	colors[6] = "cyan"
	local allplayers = player.GetAll()
	 for k, v in pairs (allplayers) do
	   if v:GetNetworkedInt( "melonteam") == i then
	   teammemcount = teammemcount + 1
	   end
	end
	   if teammemcount < GetConVarNumber( "WM_PlayersPerTeam", 1) then
223-	   ply:SetNetworkedInt( "melonteam" , i);
	     for x, y in pairs (allplayers) do
	     local message = ply:GetName() .. " has joined team " .. i .. ", (" ..colors[i].. ")."
	     Msg(ply:GetName() .. " joined team " .. i .. ", (" .. colors[i].. ").")
	     y:PrintMessage(HUD_PRINTTALK, message);
	     end
	   return
	   end
   end
end

It seems line 223 is the source of the problem in the timer.

I've looked, and apparently there is no instance when SetNetworkedInt uses "ply:" however ply is declared as a value for the function. Is this maybe a deprecated variable?

[Nazban]

Quick question about args, I have seen in timer code and others a "for" statement with no arg but just a "_," after it what does this mean should there be a arg there or is this how it works in lua? What exactly does the _, do if it is suppost to be there if it is not what arg should take the place? Here are some code examples:

[LUA]for _, str in pairs { ... } do
if not CachedMarkups[str] then
CachedMarkups[str] = markup.Parse(str)
end
end[/LUA]

[LUA]local function resupplyplayers()
for _, ply in pairs(player.GetHumans()) do
-- make sure he's alive
-- we're not interested in resupplying ghosts
if ply:Alive then
ply:GiveAmmo(60, "Pistol", true) -- feel free to change this value
ply:ChatPrint("Resupplied!")
end
end
timer.Create("Resupply", 60, 0, resupplyplayers)[/LUA]

[TheTrueAndy]

I want to set up for the very first time a particle effect on a ViewModel of a weapon.
[lua]
function SWEP:Initialize()
self:SetWeaponHoldType( self.HoldType )
ParticleEffectAttach("natur_gem", PATTACH_POINT_FOLLOW, self, 1)
end
[/lua]
I basicaly don't know how I should do it. It seems that he just can't find the ViewModel, as he doesn't throw any errors.

Help please?

It's because timer.Simple doesn't pass an argument to the function. If you're creating the timer in PlayerSpawn or PlayerInitialSpawn or somewhere you have access to the player in question, it'd be easier to make a local function specific to that player.

Also, you should not be doing it the way you're doing it.

I use a _ because it's unimportant and never used. _ is just a name of the variable.

The basic method of table iteration is to use something like this:
[lua]table = {1, 2, 3}
for key, value in pairs(table) do
print("Key:", key, "Value:", value)
end
--[[
Key: 1 Value: 1
Key: 2 Value: 2
Key: 3 Value: 3
--]][/lua]
This works even if you're using strings for keys:
[lua]complex_table = { key_one = 1, key_two = 2, key_three = 3 }
for key, value in pairs(complex_table) do
print("Key:", key, "Value:", value)
end
--[[
Key: key_one Value: 1
Key: key_two Value: 2
Key: key_three Value: 3
--]]
[/lua]
But sometimes you don't care about what the keys in the table are, because they don't matter. The only thing that matters is the contents of the table.
To save typing and confusion, you simply set the name of the key variable to be _.
[lua]
keyless_table = { 5, 7, 9 }
for _, value in pairs(keyless_table) do
print("Value:", value)
end
--[[
Value: 5
Value: 7
Value: 9
--]]
[/lua]
_ is a valid Lua variable name, and is often used when ignoring arguments in hooks or callbacks, such as
[lua]concommand.Add("mycommand", function(ply, _, args)
-- bla
end)[/lua]
or
[lua]datastream.Hook("mystream", function(ply, _, _, _, data)
-- not that anyone actually uses datastream
end)[/lua]

[find me]

[lua]
Table = {}
Table.String = ""
Table.subTable = {}

My question is, does Table = nil efficiently get rid of the table and everything in it? I'm assuming yes but I've never known for sure.

Is this impossible to trace? It happens when player spawns.
I think Player.SendLua is causing it, but I am just trying to fix this gamemode.

Unless there are other references to the subtable, yes. It'll all get picked off the next time the garbage collector runs.

Yeah that's caused by SendLua or BroadcastLua. Just do a find in files.

Is there any way to make players not collide now? I tried using [url]http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/indexa58d.html[/url]

The example didn't work, also tried:

return (ent1:Team() != ent2:Team())
end

Hey.

Even though I've seen people in other threads with incredibly similar code and theirs works fine. My code doesn't work at all regardless of where I put it. It always returns that error. Anyone have any ideas or want me to post any other info?

The ShowHelp, ShowTeam, and ShowSpare hooks are serverside, and UI elements are clientside. You'll have to send a usermessage from server to client that tells the client to create/open a panel.
