DRGBPicker

[Gigabaitt]

How can I change the color surface.SetDrawColor with the help of DRGBPicker ?

function panel()

	Panel = vgui.Create( "DPanel" )
	Panel:SetPos( 470, 320 )
	Panel:SetSize( 400, 400 )

	local But = vgui.Create( "DButton",Panel )
	But:SetPos( 350, 10 )
	But:SetText( "Close" )
	But:SetSize( 40, 20 )
	But.DoClick = function()
		Panel:Remove()
	end

	local picker = vgui.Create( "DRGBPicker", Panel )
	picker:SetPos( 5, 5 )
	picker:SetSize( 30, 155 )

	local cube = vgui.Create( "DColorCube", Panel )
	cube:SetPos( 40, 5 )
	cube:SetSize( 155, 155 )

	function picker:OnChange( col )

	local h = ColorToHSV( col )
	local _, s, v = ColorToHSV( cube:GetRGB() )

	col = HSVToColor( h, s, v )
	cube:SetColor( col )

	UpdateColors( col )

	end

	function cube:OnUserChanged( col )

	UpdateColors( col )

	end

	function UpdateColors( col )

		image:( col ) --  there

	end


end

concommand.Add( "testpanel", panel)

function image()

	surface.SetMaterial( Material( "server/image.png", "noclamp" ) )
	surface.SetDrawColor(255, 255, 255, 255) -- This is
	surface.DrawTexturedRect(15,15,256,256,256)

end

hook.Add( 'HUDPaint', 'image', image)

You could create a new variable at the top of your code, like

local color = color_white

Then just do

function UpdateColors( col )

	color = col

end

And then in the image() function do

surface.SetDrawColor(color.r, color.g, color.b, color.a)

Or, if you want the full code:

local color = color_white -- Create the color variable (I set it as white for no reason in particular)

function panel() -- please make this function local :(

	Panel = vgui.Create( "DPanel" ) -- please make this variable local :(
	Panel:SetPos( 470, 320 )
	Panel:SetSize( 400, 400 )

	local But = vgui.Create( "DButton",Panel )
	But:SetPos( 350, 10 )
	But:SetText( "Close" )
	But:SetSize( 40, 20 )
	But.DoClick = function()
		Panel:Remove()
	end

	local picker = vgui.Create( "DRGBPicker", Panel )
	picker:SetPos( 5, 5 )
	picker:SetSize( 30, 155 )

	local cube = vgui.Create( "DColorCube", Panel )
	cube:SetPos( 40, 5 )
	cube:SetSize( 155, 155 )

	function picker:OnChange( col )

	local h = ColorToHSV( col )
	local _, s, v = ColorToHSV( cube:GetRGB() )

	col = HSVToColor( h, s, v )
	cube:SetColor( col )

	color = col -- Set the variable

	end

	function cube:OnUserChanged( col )

		color = col -- Set the variable

	end

end

concommand.Add( "testpanel", panel)

function image() -- please make this function local :(

	surface.SetMaterial( Material( "server/image.png", "noclamp" ) )
	surface.SetDrawColor(color.r, color.g, color.b, color.a) -- Get the r,g,b,a values of the variable
	surface.DrawTexturedRect(15,15,256,256,256)

end

hook.Add( 'HUDPaint', 'image', image)

(I shortened the code above by removing the function you created, since it wasn't really needed)
