The Ultimate Guide to Derma - Everything there is to know about Derma

[PC Camp]

I understand what your all saying about the looping stuff, but for now I just want to fill out all the libraries. My original plan was just to paste exactly how each part of Derma works. Like how I did above.

Later on I will then go in depth about VGUI and coding more efficiently.

I will also include other examples other than concommands.

[b]Edit:[/b]

[QUOTE=garry]FYI, DCollapsibleCategory is really designed to be used in a DPanelList (as seen in the map selection/toolbar/etc).[/QUOTE]

I noticed that while going through the spawnmenu to find out how it worked. But it seems like there are other was to use it.

[superadamwo]

For some reason when I open a derma panel I made the mouse doesn't appear, and instead I can look around like normal, which means the only way I can press something is if I open the console first so I can see my mouse. Is there a reason why that happens?

[PC Camp]

I'm not to sure why that happens. Post your code then I'll be able to tell.

[PC Camp]

I have a feeling it has to do with
[lua]test:MouseCapture(true)[/lua]

Also try Creating your Derma items before you code them. I wouldn't just create them at the top then work your way down like that.

[b]Edit:[/b]

Try taking that line out. Then what happens?

[superadamwo]

With or without mousecapture, it still doesn't work. I added that in a couple minutes ago to see if it would fix it.

[PC Camp]

Alright I know what's wrong.

Replace
[lua]test:MakePopup()[/lua]

With
[lua]test:MouseCapture(true)[/lua]

You need to make the frame appear.

Here's your frame the way I'd do it. Should work, not tested.

[lua]
function testpanel() // Create the function

test = vgui.Create("DFrame") // Create the frame
test:SetPos(50,50) // set the frame's position on the screen
test:SetSize(500, 500) // set the frame size
test:SetTitle( "Madness Evolved" ) // set the frame title
test:SetVisible( true ) // Make the frame visible
test:SetDraggable( true ) -- Draggable by mouse?
test:ShowCloseButton( true ) -- Show the close button?
test:MakePopup() -- Show the frame. THIS IS WHAT YOU MISSED

menu1 = vgui.Create("DButton")
menu1:SetParent( test ) // parent the button to the frame
menu1:SetText( "Weapons >" ) // set the button text
menu1:SetPos(51, 150) // set the button position in the frame
menu1:SetSize( 100, 20 ) // set the button size
menu1.DoClick = function () // this will be called when the button is clicked
local menu123 = DermaMenu() // create a derma menu
menu123:AddOption("hello", function() Msg("Hello") end ) // adding options
menu123:AddOption("how", function() Msg("How") end )
menu123:AddOption("are", function() Msg("Are") end )
menu123:AddOption("you", function() Msg("You") end )
menu123:AddOption("?", function() Msg("?") end )
menu123:Open()
end // ending the doclick function

menu2 = vgui.Create("DButton")
menu2:SetParent( test )
menu2:SetText( "Kill >" )
menu2:SetPos(150, 150)
menu2:SetSize( 100, 20 )
menu2.DoClick = function () // this will be called when the button is clicked
local menu223 = DermaMenu() // create a derma menu
menu223:AddOption("Ignite", RunConsoleCommand("igniteplayer", "LocalPlayer()")) // adding options
menu223:AddOption("Normal Kill", function() LocalPlayer():ConCommand("kill") end)
menu223:AddOption("Time Bomb", RunConsoleCommand("timebomb", "LocalPlayer()"))
menu223:AddOption("Gravity Kill", RunConsoleCommand("gravitykill"))
menu223:AddOption("Force Kill", function() Msg("?") end )
menu223:Open()
end // ending the doclick function

menu3 = vgui.Create("DButton")
menu3:SetParent( test )
menu3:SetText( "Powerups >" )
menu3:SetPos(250, 150)
menu3:SetSize( 100, 20 )
menu3.DoClick = function () // this will be called when the button is clicked
local menu323 = DermaMenu() // create a derma menu

menu323:AddOption("you", function() Msg("You") end )
menu323:AddOption("?", function() Msg("?") end )
menu323:Open()
end // ending the doclick function

menu4 = vgui.Create("DButton")
menu4:SetParent( test )
menu4:SetText( "Options >" )
menu4:SetPos(350, 150)
menu4:SetSize( 100, 20 )
menu4.DoClick = function () // this will be called when the button is clicked
local menu423 = DermaMenu() // create a derma menu

Good luck man.

[PC Camp]

You could do that also. I think it's easier for new learners to understand it directly. Thanks though. :)

[superadamwo]

Worked, thanks. Was it not working because I did MakePopup after defining the buttons or something?

[PC Camp]

I think so. For some reason you must define everything in chronological order. For example, look at how I did the DPanelList.

[superadamwo]

Well that's annoying.

[Bang Train]

Two things:
1. How can I make F1 toggle a window? I have it open it but haven't been able to make it close it if it's open.
2. No one gave me a good working answer on how to change a DLabel's text size.

Can you answer these?

[ChewGum]

What if you wanna make it so you can open it by a command? :)

[Bang Train]

[QUOTE=ChewGum]What if you wanna make it so you can open it by a command? :)[/QUOTE]

concommand.Add("showMenu",ShowMenu)

ShowMenu() is a function to create the menu

something similar to this

[lua]
vgui.Register( "Menu",PANEL, "DFrame" )
DermaMenu = nil
function ShowMenu()
DermaMenu = vgui.Create("Menu")
DermaMenu:MakePopup()
DermaMenu:Center()

Why would you register "Menu" when there is nothing there? PANEL isn't defined, and the whole thing is just broken.
[lua]
function ShowMenu()
DermaMenu = vgui.Create("DFrame")
// Remember to set the size and position.
DermaMenu:MakePopup()
DermaMenu:Center()

vgui.Register( "Menu",PANEL, "DFrame" )

Still completely useless and unnecessary. You're creating a custom blank VGUI element derived from DFrame. When there's one exactly like it already... Called DFrame!

[lua]
Value_One = "Pies" -- This one isn't good enough for us.
Value_Two = Value_One
print( "I'd like some " .. Value_Two .. "." ) -- That's better.
[/lua]

[superadamwo]

I've been trying to figure out the same thing as Bang Train, sort of. I've been looking for a function that will cause my menu to open when a player holds down Q, and close when they let go.

[Kiporsnikov]

[lua]function QMenuOn( pl, Key )
if ( Key == KEY_Q ) then
// Open the menu
end
end
hook.Add( "KeyPress", "Lolque", QMenuOn )

function QMenuOff( pl, Key )
if ( Key == KEY_Q ) then
// Close the menu
end
end
hook.Add( "KeyRelease", "Lolwut", QMenuOff )
[/lua]

See:
[url]http://www.garrysmod.com/wiki/?title=Gamemode.KeyRelease[/url]
[url]http://www.garrysmod.com/wiki/?title=Gamemode.KeyPress[/url]
[url]http://www.garrysmod.com/wiki/?title=IN_KEYS[/url]
[url]http://www.garrysmod.com/wiki/?title=Hook.Add[/url]

[superadamwo]

I thought I looked at every hook with the word "key" in it. I guess not. Fuck...
Now one more thing I never understood when I looked at scripts is why people put two functions in if they only use one. You put in pl and key, but you only used key. Why is that?
Also I tried it that way and it didn't work. So then I just tried:
[lua]
function QMenuOn( pl, Key )
if ( Key == KEY_Q ) then
Msg("LGBBBVHKHBVLHK")
end
end

hook.Add( "KeyPress", "QMenuOn", QMenuOn )
[/lua]
But that didn't work either :(

[PC Camp]

Do a think hook and use [url=http://garrysmod.com/wiki/?title=Player.KeyDown]KeyDown()[/url]. I'd help and provide an example but I have a term paper to get done. Sorry. :(

[Kiporsnikov]

I tried something else, but it appears that the whole system is bugged.
[lua]
if pl:KeyDown( KEY_Q ) then
print( "IT'S ON!" )
end
[/lua]
That returns true at random.

If I were you, I'd hook into SpawnMenuOpen or something like that. Either that, or one of the F* functions.

[PC Camp]

If you do this
[lua]
function SeeIfTheirKeyIsDown()
for k, v in pairs(player.GetAll()) do
if v:KeyDown( KEY_Q ) then
Msg("Holding Q down\n")
-- Create panel here
end
end
end
hook.Add("Think", "Your Think Hook", SeeIfTheirKeyIsDown)
[/lua]
it will work.

Tested, works fine. :)

[superadamwo]

Doesn't a "think" hook lag a lot? Also why did you need to put the loop there, couldn't you have just done:
[lua]
function SeeIfTheirKeyIsDown()
if LocalPlayer():KeyDown( KEY_Q ) then
Msg("Holding Q down\n")
-- Create panel here
end
end
end
hook.Add("Think", "Your Think Hook", SeeIfTheirKeyIsDown)
[/lua]
Since the think hook is running the function every frame anyway. Also the other problem is that the derma panel will repeatedly open while you hold down Q so you'll end up with hundreds of them, and I just want it to create one and then keep that one open until I let go of Q.
And Kiporsnikov, I can't use SpawnMenuOpen because the spawn menu is disabled in my gamemode, and holding down Q with it disabled makes the function return false.

[Ben Build]

wouldn't
hook.Add("OnSpawnMenuOpen", "OpenMyPanel", CreatePanel())
and
hook.Add("OnSpawnMenuClose", "CloseMyPanel", OnSpawnMenuClose())
be better?

don't forget to create your panel with a variable eg

myqpanel = vgui.Create("dpanel")

so on close you can do

myqpanel:Remove()

if that hook fails you can always check the concommand +menu and -menu

I think that hook i used is in the base so you shouldn't have to use the concommand also if you don't want the spawnmenu to come up either don't derive from sandbox or return false at the end of the CreatePanel() function.

[PC Camp]

Well
[lua]LocalPlayer()[/lua]
should always be used on client scripts. [b]Very[/b] rarely will LocalPlayer() not come up nil.

When using
[lua]for k, v in pairs(player.GetAll()) do[/lua]
your cycling through all the players to see if they have that key down.

For your request, I'll look into that. I've never made a toggling frame by holding down a key. If anything I'd do two concommands like "+panel" and "-panel".

I'll write something up that will work like how you want it.

[Kiporsnikov]

[QUOTE=Ben Build]wouldn't
hook.Add("OnSpawnMenuOpen", "OpenMyPanel", CreatePanel())
and
hook.Add("OnSpawnMenuClose", "CloseMyPanel", OnSpawnMenuClose())
be better?

This is the best approach.
