Surface.CreateFont block any command...

[Naografix]

Hey Facepunch

I want to create a PaintTool with a chatCommand.
My PaintTool use Cam3d2d to create HUD in the World.

But i have a problem and i dont know why :

Paint = {}
Paint.Active = false

function Paint.GetInfo( ply, text, public )

	if (string.sub(text, 1, 6) == "!Paint") then

		local textexplode = string.Explode( " ", text )
		local Index = textexplode[2]
		local Text = textexplode[3]
		local Size = textexplode[4]
		local Trace = ply:GetEyeTrace()
		local Position = Trace.HitPos

		surface.CreateFont("CV"..tostring(Index), {
			font = "coolvetica",
			size = Size,
			weight = 400,
			antialias = true,
			outline = true,
		} )


		RunConsoleCommand("say", Index)
		RunConsoleCommand("say", Text)
		RunConsoleCommand("say", Size)
		RunConsoleCommand("say", tostring(Position))



		Paint.AddText(Index, Text, Size, Position)


	end

end

hook.Add( "PlayerSay", "SayPaint", Paint.GetInfo)

My runConsoleCommand dosent want to execute.

Its like if my surface.Create block this command... and i don't understand why...

Can you help me plz ?

Thx

What console command are you trying to use? You dont have one in the code.

[Naografix]

I want when i type : !Paint [INDEX TEXT SIZE] -> !Paint 1 Test 50
My font has to be created and my Console say : Index, Text, Size and Position of my player.

[G4MB!T]

[URL="http://wiki.garrysmod.com/page/GM/PlayerSay"]PlayerSay[/URL] is a server-side hook. Why dont you just make a console command for it?

[Naografix]

My problem its just : runConsoleCommand dosent want execut.

If i made this :

function Paint.GetInfo( ply, text, public )

	if (string.sub(text, 1, 6) == "!Paint") then

		local textexplode = string.Explode( " ", text )
		local Index = textexplode[2]
		local Text = textexplode[3]
		local Size = textexplode[4]
		local Trace = ply:GetEyeTrace()
		local Position = Trace.HitPos

                RunConsoleCommand("say", Index)
		RunConsoleCommand("say", Text)
		RunConsoleCommand("say", Size)
		RunConsoleCommand("say", tostring(Position))

		surface.CreateFont("CV"..tostring(Index), {
			font = "coolvetica",
			size = Size,
			weight = 400,
			antialias = true,
			outline = true,
		} )

		Paint.AddText(Index, Text, Size, Position)


	end

end

My console can speak

I think i have an error on my surface.Create but where...
I use this : [url]http://wiki.garrysmod.com/page/surface/CreateFont[/url]

You are using 2 functions from different realms. PlayerSay is server-side like I told you, so hooking into it on the client will never get called. surface.CreateFont is client-side, so trying to use it in a server-side hook will error, but since your PlayerSay hook is never called on the client, the code inside is never executed.

[Naografix]

Then what is your solution ?

[Mista Tea]

Switch [B]PlayerSay[/B] to [URL="http://wiki.garrysmod.com/page/GM/OnPlayerChat"][B]OnPlayerChat[/B] [/URL]if you want this to be purely [U]clientside[/U].

However, using OnPlayerChat means any serverside admin mods that return a blank string ("") for commands like !command or /command will prevent your OnPlayerChat from ever actually running.

Instead,[B] stick with PlayerSay[/B] and put the hook inside of a serverside file.

-- Serverside file. Example: lua/server/paint.lua
function Paint.GetInfo( ply, text, public )
    if ( text:sub(1, 6):lower() == "!paint" ) then -- :lower() is so you can type !paint, !Paint, !PAINT, etc
        local textexplode = string.Explode( " ", text )
        local Index = textexplode[2]
        local Text  = textexplode[3]
        local Size   = textexplode[4]

        net.Start( "AddPaintText" )
            net.WriteFloat( Index ) -- net.WriteUInt if you know the amount of bits
            net.WriteString( Text )
            net.WriteFloat( Size )  -- net.WriteUInt if you know the amount of bits
        net.Send( ply )
    end
end
hook.Add( "PlayerSay", "SayPaint", Paint.GetInfo )

Then move this stuff into a clientside file and use net messages to tell the client to run it (alternative, use concommand):

-- Clientside file. Example: lua/client/paint.lua
net.Receive( "AddPaintText", function( bits )
    local Index = net.ReadFloat()
    local Text = net.ReadString()
    local Size = net.ReadFloat()

    local Trace = LocalPlayer():GetEyeTrace()    
    local Position = Trace.HitPos

    RunConsoleCommand("say", Index)
    RunConsoleCommand("say", Text)
    RunConsoleCommand("say", Size)
    RunConsoleCommand("say", tostring(Position))

    surface.CreateFont("CV"..tostring(Index), {
         font = "coolvetica",
        size = Size,
        weight = 400,
        antialias = true,
        outline = true,
    } )
    Paint.AddText(Index, Text, Size, Position)
end

Hooo okay man :) thank you, Really !

I test your code tomorow ! Its Really informative for me, thx again

[Mista Tea]

[QUOTE=Naografix;45413909]Hooo okay man :) thank you, Really !

No problem. I haven't personally tested it, so if you have any further issues, be sure to post here again and we'll try to help.

--Edit--

I accidentally left out two [B]end[/B]s in the first code snippet, so make sure to re-copy it when you test it tomorrow. My bad :)

[Naografix]

Okay ! Good night ^^

[Naografix]

Yep !

Okay, well. I see in your code you said : -- Clientside file. Example: lua/client/paint.lua and server/paint.lua
Then i think i can make : if SERVER then ... else ... end

But already same

Paint = {}
Paint.Active = false

if SERVER then
	-- Serverside file. Example: lua/server/paint.lua
	function Paint.GetInfo( ply, text, public )
	    if ( text:sub(1, 6):lower() == "!paint" ) then -- :lower() is so you can type !paint, !Paint, !PAINT, etc
	        local textexplode = string.Explode( " ", text )
	        local Index = textexplode[2]
	        local Text  = textexplode[3]
	        local Size   = textexplode[4]

	        net.Start( "AddPaintText" )
	            net.WriteFloat( Index ) -- net.WriteUInt if you know the amount of bits
	            net.WriteString( Text )
	            net.WriteFloat( Size )  -- net.WriteUInt if you know the amount of bits
	        net.Send( ply )
	    end
	end
	hook.Add( "PlayerSay", "SayPaint", Paint.GetInfo )


else


		-- Clientside file. Example: lua/client/paint.lua
	net.Receive( "AddPaintText", function( bits )
	    local Index = net.ReadFloat()
	    local Text = net.ReadString()
	    local Size = net.ReadFloat()

	    local Trace = LocalPlayer():GetEyeTrace()    
	    local Position = Trace.HitPos

	    RunConsoleCommand("say", Index)
	    RunConsoleCommand("say", Text)
	    RunConsoleCommand("say", Size)
	    RunConsoleCommand("say", tostring(Position))

	    surface.CreateFont("CV"..tostring(Index), {
	         font = "coolvetica",
	        size = Size,
	        weight = 400,
	        antialias = true,
	        outline = true,
	    } )
	    Paint.AddText(Index, Text, Size, Position)
	end)

	function Paint.AddText(Index, Text, Size, Position)

		local Item = {}
		
		Item.Index = Index
		Item.Text = Text
		Item.Size = Size
		Item.Position = Position

		table.insert(Paint.Stored, Item)

		Paint.Active = true
	end




	function Paint.PaintHook()
		if not Paint.Active then return end
		for _, Item in pairs(Paint.Stored) do
			local Text = Item.Text
			local Position = Item.Position
			local Angles = Angle(0,0,0)
			local Size = Item.Size
			local Index = Item.Index
			
			local Alpha = 255
			local Color = Color(255,0,0)
			
			cam.Start3D2D(Position, Angles, 0.25)
				draw.DrawText(Text, "CV"..tostring(Index), 0, 0, Color, TEXT_ALIGN_CENTER)
			cam.End3D2D()
		end
	end
	hook.Add("PostDrawOpaqueRenderables", "Paint.PaintHook", Paint.PaintHook)

end

I begin the lua language, excuse me ^^'

(To test my code i use : lua dev with this command : lua_send_sh Paint.lua)

You are executing the "say" console command too fast. There's a delay before you can use it again.

[Mista Tea]

Woops, I forgot to mention that you need to cache the net message.

if SERVER then
	-- Serverside file. Example: lua/server/paint.lua
        
        util.AddNetworkString( "AddPaintText" ) -- cache the message name so we can send it        

	function Paint.GetInfo( ply, text, public )
	    if ( text:sub(1, 6):lower() == "!paint" ) then -- :lower() is so you can type !paint, !Paint, !PAINT, etc
	        local textexplode = string.Explode( " ", text )
	        local Index = textexplode[2]
	        local Text  = textexplode[3]
	        local Size   = textexplode[4]

	        net.Start( "AddPaintText" )
	            net.WriteFloat( Index ) -- net.WriteUInt if you know the amount of bits
	            net.WriteString( Text )
	            net.WriteFloat( Size )  -- net.WriteUInt if you know the amount of bits
	        net.Send( ply )
	    end
	end
	hook.Add( "PlayerSay", "SayPaint", Paint.GetInfo )

If you're using those RunConsoleCommand("say",...) parts just for testing, you could switch it to print( Index ), print( Text), print( Position ). If you want it to show up in chat instead, you could use chat.AddText( Index ), etc.
