[QUOTE=MPan1;49573071]If I use 0 and ScrW() and math.Approach works how I think it does, won't it just do nothing unless it reaches 0 or ScrW()? What's the point of it? I want the movement to be smooth, not just do some odd thing once it reaches 0 or ScrW()...[/QUOTE]

math.Approach, according to the wiki page, "Increments a value from a start point by the given amount, up to a given upper limit."

Using Zombine's example, it would increment by RealFrameTime()*8 each time it was called.

I think math.Approach is a bit useless because it's really just an if statement. I gave you a code snippet a while ago while you were trying to have a bar's width increase at a set rate regardless of framerate. That code can be used again here.

local value = 0
local width = ScrW()

value = math.min( width, value + ( width * RealFrameTime() / seconds ) )

if value == width then
  --do stuff
end

Just set seconds to the number of seconds you want it to take to traverse the screen and use value for the draw call. In the if statement you can remove the object or whatever to stop it drawing when it's no longer on the screen.

I have a vgui question now:

How would I get a child of a DFrame to firstly un-dock from it's parent (if necessary), then go fullscreen? Or, should I try to get the parent of the child element to go fullscreen? I don't really know what to do.

All I want to do is get a DFrame to appear like it's going fullscreen with a DButton docked into it

[editline]21st January 2016[/editline]

EDIT: I think I figured it out. I needed to set the DFrame's docking to 0, 0, 0 and invalidate some stuff

[kpjVideo]

Not too much of a problem, but I'm trying to allow players to see all around them when in thirdperson (freelook) but I can't seem to figure out how to allow all of the angles.

I've attempted editing the view.angles to pretty much everything I could think of. (Angles, Player's Angles, Math applied to players angles, etc)

            local View = { }
            View.origin = Trace.HitPos + Player:GetForward() * 8
            View.angles = Player:GetAngles()
            View.fov = Fov

            return View

Really small and simple I know, maybe I'm just too stupid.

[MysteryPancake]

So...roastchicken, with the code snippet you gave me:
[QUOTE=roastchicken;49573236]

value = math.min( width, value + ( width * RealFrameTime() / seconds ) )

[/QUOTE]
What am I supposed to do if the speed is 0? Everything just flies off screen if I try to use your example. Also, since I want the number to get smaller rather than bigger (the stuff is all being created at ScrW()), I did this instead:

value = math.min( width, value - ( width * RealFrameTime() / seconds ) )

So that's probably why it's screwing up. Could you help me?

Okay, I have another question- is there a way in Lua to change a variable in a literal way with a function like so:

local var

local function changevar( variable )
variable = 'test'
end

changevar( var )

print( var )
--> nil
-- how could I get it to print 'test' ?

Except get the code above to somehow make the variable actually get changed? No idea how this could be done, probably with some dodgy table indexing or something

You should really not have code that works like this in Lua. If you really need to, you could fight with debug.setupvalue.

[man with hat]

As said before, just use tables. There's nothing dodgy about them. I guarantee that whatever you're doing doesn't need to do what you're trying to do now.

[MysteryPancake]

I meant table indexing as in table indexing the _G table (containing all global variables as far as I know) or whatever the equivalent is for local variables

I should be using tables but I was just trying to condense a bit of code that sets a variable based on whether or not a DCheckBox is ticked. It was only a little bit of code anyway so it doesn't really matter

Is there a way to make sure, if you're using AnimRestartGesture, that the ACT you use will always be the same for the client and the server? Because right now they're desynced, as the ACT has I think 7 different variations (ACT_GMOD_GESTURE_RANGE_ZOMBIE). I want it to use the same variation for both client and server, per call. I have a pretty limited knowledge of the animation functions so I might be missing something obvious here.

That's how ACTs work, one ACT may have multiple sequences assigned to it:
[url]https://github.com/robotboy655/gmod-animations/blob/master/gm_sequences_zombie.qci#L133-L139[/url]

If you wish for them to be synched, you gotta play sequences.

I had also made one where the value decreased, but I didn't post it. I'll see if I can figure it out again.

How do I put a particle in front of a player?

I'm feeling stupid. Script is in GM:PlayerInitialSpawn and should remove all the shitty props around the map. No error just not working.

	if !FIRSTJOINED then

				v:Remove()

Thanks in advance.

how would I make a map show a users current STEAMname on item use with lua_run

like they consume an item, I kill the item with hammers i/o system they get hp or something but it also messages the entire server like "STEAMNAME used the health item"
possible?

You should put this in InitPostEntity and use ent:CreatedByMap() in your loop. Also make sure you are using hook.Add to make your hook.

Well, probably don't use lua_run for it, just put the code in a .lua file in the garrysmod/lua/autorun folder (if the server you're on had lua_run enabled just so you could manually run one thing then anyone could type any command and screw up the whole server). Anyway, this would probably work:

--SERVERSIDE STUFF

AddCSLuaFile( 'lua/whatever_folder/whatever_the_name_of_your_clientside_code_file_would_be.lua' ) -- the clientside file of this needs to be sent to the client, that's what AddCSLuaFile does

util.AddNetworkString( 'SendChatToPlayers' ) -- since gmod doesn't allow server-wide chat we have to use the net library :(

hook.Add( 'PlayerUse', 'UNIQUE_NAME', function( ply, ent ) -- make sure to change UNIQUE_NAME to a unique name so this hook doesn't get overwritten by some other addon
    if ent:GetModel() == 'whatever model it is' then -- you could do something different to this but this is just an example
        ply:SetHealth( ply:Health() + 10 ) -- add 10 hp for example
        ent:Remove() -- you don't need to use hammer for this :P
        net.Start( 'SendChatToPlayers' ) -- start the thing that makes the chat say whatever player ate it
        net.WriteEntity( ply ) -- send the player who ate it
        net.Broadcast() -- send it to all players on the server so it shows all of them who ate it
    end
end )

-- CLIENTSIDE STUFF (note you need to do AddCSLuaFile on whatever .lua file this code will be in, as I did an example of in the serverside code above)

net.Receive( 'SendChatToPlayers', function()
    local ply = net.ReadEntity() -- read the player entity we sent
    chat.AddText( Color( 100, 100, 255 ), ply, " used the health item!" ) -- that prints the text you wanted
end )

[editline]22nd January 2016[/editline]

Also, I have a question-
I'm working on a really simple swear remover just for fun, and I have a long list of swear words to remove, which my code just finds in the chat string a player says and string-subs them out. But, my question is this:

Say a player says something like

sh-it

Or uses some kind of other character to make a gap between what would be a swear word so it gets undetected. How would I somehow remove the - character, and then check if it's a swear word, and if so, replace it with some other letter like *? I really have no idea how that could be done...
Here's my code for replacing the letters (it's pretty messy though):

hook.Add( 'PlayerSay', 'RemoveSwears', function( sender, text, bTeamChat )

	local Violators = {}
	
	text = string.Replace( text, '-', '' ) -- current i'm just subbing out the character, but then if a player says something like hot-dog it would turn into hotdog, which I don't want to happen
	
	for word in pairs( Swears ) do -- Swears is the name of the table with all the swears in it
		local s, e = string.find( string.lower( text ), word )
		if s ~= nil then
			Violators[ #Violators+1 ] = { start = s, finish = e }
		end
	end
	
	for _, PosTab in ipairs( Violators ) do
		text = string.sub( text, 0, PosTab.start - 1 ) .. string.rep( '*', PosTab.finish + 1 - PosTab.start ) .. string.sub( text, PosTab.finish + 1, #text )
	end
		
	return text

end )

I want to kick myself right now for not posting/saving the code for the constant rate of decreasing. I swear I had an equally elegant solution that just required swapping out an operator and maybe switching min to max, but now I can't seem to think of it.

This is the best I could do:

local value = ScrW()
local width = 0
local difference = math.abs( value - width )

value = math.max( width, value + ( difference * RealFrameTime() / seconds ) )

if value == width then
  --do stuff
end

[editline]22nd January 2016[/editline]

I appreciate the code

id rather have in included in the map with lua_run so no extra files are needed
I just need the chat stuff really, I can do the damage stuff in hammer easily with trigger_hurt

[roastchicken]

I'm sure it was more elegant than that but I'm going to stop beating myself up for it. Hope it solved your problem.

Can you do lua_run_cl in hammer? If so, just run the clientside bit with that and the serverside bit with lua_run and it would probably work. Take away that health adding thing though and the entity:Remove bit if you don't want to use them, then just remove all the paragraphs by replacing them with spaces and try running the code and see what happens

[roastchicken]

I guess my original code wasn't as modular as I thought

local start = 0 --starting value
local stop = 100 --ending value
local seconds = 1 --number of seconds you want it to take

local diff = stop - start
local value = start

if value ~= stop then
  value = value + ( diff * RealFrameTime() / seconds )
else
  --do stuff
end

I can now sleep easy

Well, good luck. The reason you need a clientside file by the way is because you can only print text in chat on the client's side, so unless Hammer has some way to print text to all players without using any clientside files, I guess you'll have to try whatever you're trying now. It would be a hell of a lot easier if you just let the clientside .lua file be a separate thing from the map, though :P

How can I add 'dummy' DPanels to a DListLayout?

I'm trying to make a leaderboard (which I've never done before, by the way) and since I'm testing it only with a couple of players, so there's lots of empty space on it and it looks bad. I want to fill the empty space with some DPanels or something so it looks like they're spots to be taken, like how the DListView adds all those blue and white stripes even when there's nothing in them. How could I do this in a way that will make sure all the possible space will be filled?

lua_run creates two variables - ACTIVATOR and CALLER. Experiment with it, but something like that should work.

can I paint the lines in DNumSlider somehow`??

:snip: Figured it out

[B]EDIT:[/B] Nope, I didn't

This is probably a really simple maths question, but:

If I had a screen width of [B]1920[/B], then I want a variable to be set as [B]100[/B].
If I had a screen width of [B]1176[/B], then I want a variable to be set as [B]84[/B].

Or as close to the second number as possible. What equation am I meant to do to the first number to get it as close as possible to the second one? Also, I want the equation to be the same for both numbers so it works for all screen resolutions.

How could I do this?

[B]EDIT:[/B] Nevermind, I'll just use different numbers
