To Clients using LuaCraft, yes!

Ignore ^'s post. You can't do this yet. :P You can however use Player:SendLua() serverside.

[lua]
hook.Add("PlayerSpawn", "SendLua", function(ply)
ply:SendLua[[
print("Hello there " .. LocalPlayer():Name() .. "! :)")
]]
end)
[/lua]

Ahh, well, better than nothing :)
Is a solution similar to GMod's way planned?

Wait, the client simply tells the server that it's broken a block?
Couldn't you knock out the entire map with that?

[BlackAwps]

Luckily no. The server has checks to prevent that. :v:

[QUOTE=ruarai;34549401]Actually, wait I get a single java error when I load the world.
[url]http://i.cubeupload.com/WtAI8q.png[/url][/QUOTE]

You get that error because the player isn't initialized when the script loads. ( Same as in Garry's Mod. )

[bobthe2lol]

I suddenly want to write a game mode like thing. Hmm...

When is local player ever a wolf?

[bobthe2lol]

Is there some way to include other lua files? For example, I have a lua file named arena.lua in the same folder as my init.lua. Inside arena.lua I stuck module(..., package.seeall) at the top, but on requiring 'arena', I get a lua error telling me that arena.lua does not exist, even though I can obviously see it right there. Is there some sort of directory structure or include directory that I should use?

[victormeriqui_1]

hmm, is trace.Entity broken?

something like this always returns nil for me:

local me = LocalPlayer()

for k, v in pairs(ents.GetAll()) do
	
	if v:IsValid() and (v:IsPlayer() or v:IsMob() or v:IsLiving()) and v ~= me then
	
		local tr = TraceLine( 
		{
		        start = me:EyePos(),
			endpos = v:EyePos(),
			world = me:GetWorld(),
	 	        dimension= me:Dimension(),
		 } )
		print(tr.Entity)

	end
end

Use the include function? :v:

[QUOTE=victormeriqui_1;34550188]hmm, is trace.Entity broken?[/QUOTE]

Try using table.Print on the entire tr table. Make sure me isn't nil, print eyepos of both me and v, etc.. Pretty much any debugging information would help.

[/QUOTE]

Just an FYI. The world and dimension index does nothing on the client. The only world the player knows about is the world they are currently in, so TraceLine on the client automatically uses the current world. Same with the World() global on the client. It will only ever return the world the client is currently in.

Anyway, I'll look and see if it ever returns a hit entity on the client.

I had the same problem just a few hours ago. I honestly couldn't find a simple solution so I just used loadstring() on the files I wanted to include.

And to @@s comment, unless I was using it incorrectly the include() function doesn't do shit for me.

Is there documentation for the surface and other drawing libraries?

Is there some kind of "AddCSLuaFile" for servers, and if not, will there ever be? That would complete the awesomness for me.

And does the server list when you click Multiplayer only pick up servers running LuaCraft? If so, that's awesome too.

You can use player:SendLua[[]] upto something like 4mb of data. Sending files to the client will come after the ad dons system is fully implanted.

In init.lua simply call include("arena.lua")

Working on Multi-Chat allowing servers chat to be seen across servers that use the addon.

The system i have isn't perfect, it updates every second or so and because it overwrites the message already on the webpage, messages might not get received before they are overwritten. I'm going to work on a different way of doing this.

[bobthe2lol]

Can someone explain how player.command works? Specifically, what the command prefix is? I assume it's something like /command arg1 arg2, but that doesn't seem to call the player.command hook...

[Bellminator]

[QUOTE=LuaStoned;34556805]In init.lua simply call include("arena.lua")[/QUOTE]

Experimented a bit and realized it was returning a java error because I tried calling include() after the server had initialized.

Anything with the prefix of "/" ( without quotes ) will call the hook. With the first arg being the command ( example: "/command" ).

Having already made a multi-server chat script, you are much better off using minecrafts built in rcon to run a command.

Does this work on Linux? I am trying it and it is saying my JSON is wrong, when it isn't.

You're using the old info.txt format. Use the new format.
