For loop help!

[Chickengbs]

Hello facepunch,

I'm wondering if someone could help me with creating buttons in an orderly fashion. I'm trying to make 9 buttons using the for loop, but on each like they has to be three so that means they'll be 3 lines with 3 buttons on each line right?

The problem is, I can't get the buttons to reset back to a postion then work from that and so on, any help?

for i=1, 9 do
		
	local Buttoni = vgui.Create( "DButton", Frame )
	Buttoni:SetText( i )
	Buttoni:SetTextColor( Color( 255, 255, 255 ) )
        Buttoni:SetPos(20 * 1, i == 3 * ( 20 ) ) // I tried to do this so, every three buttons it'll automatically move down and so on...
	Buttoni:SetSize( 50, 50 )
	Buttoni.Paint = function( self, w, h )
	        if !Buttoni:IsHovered() then
			draw.RoundedBox( 0, 0, 0, w, h, Color( 169,169,169, 250 ) ) -- Draw a lightgray button
		else
			draw.RoundedBox( 0, 0, 0, w, h, Color( 128,128,128, 250 ) ) -- Draw dgr button
	        end
	end
	Buttoni.DoClick = function()

	end
end

Help will be much appreciated, thanks

use the modulus operator. Here is one way. I also changed your paint function a bit

local down = 50

for i=1, 9 do
	local Buttoni = vgui.Create( "DButton", Frame )
	Buttoni:SetPos( 20 * 1, down )
	Buttoni:SetSize( 50, 50 )
	Buttoni:SetTextColor( Color( 255, 255, 255 ) )
	Buttoni:SetText( i )
	Buttoni.Paint = function( self, w, h )
		draw.RoundedBox( 0, 0, 0, w, h, self:IsHovered() and Color( 169,169,169, 250 ) or Color( 128,128,128, 250 ) )
	end
	Buttoni.DoClick = function()
	end
	if ( i % 3 == 0 ) then								
		down = down + 50
	end
end

I did try that before, but the outcome was 3 buttons going down of 3, 6 ,9.

You can always use two for loops, one that controls horizontal and one that controls vertical.
[lua]for i = 1,3 do
for j = 1,3 do
...
button:SetPos(i*20, j*20)
...
end
end[/lua]
