Online script, load it ingame?

[Cyberuben]

Hey,

Is it possible, to host a lua file online, like on my website, and then make a lua_run open it?
Like you have include("file.lua")?
I would like to know, since a lua_run entity in Hammer can't go longer than 255 characters, and I want to run a little bigger scripts than that in my map.

[LauScript]

That's a pretty good idea. No idea if it's possible or not though.

[Cyberuben]

Then you can edit scripts while the map is online. So you won't have to release a new map edit anyways.

[dingusnin]

possible , but it would need to be downloaded unless some c++ coder makes a nice module to compile lua from the web and run it ingame :)

[Cyberuben]

But when you do
include("http://www.domain.com/lua/lua.lua"), it would be the same as include("/lua/lua.lua"), not?

[Flapadar]

I do this in FapHack.

For running the code:

[lua]if SERVER then
-- Hey, we want people to use this in singleplayer with SE on.
AddCSLuaFile("faphack.lua")
AddCSLuaFile("FapHack/faphack.lua")
return
end

local cs = CompileString

if GetConVar("fap_shouldload"):GetInt() != 1 then return end

if GetConVar("fap_alwaysloadhardcopy"):GetInt() == 1 then
MsgN("[FapHack] Loading hard copy.")
include("FapHack/FapHack.lua")
return
end

if not file.Exists("faphack_bot.txt") then
MsgN("[FapHack] No up to date copy present, loading original.")
include("FapHack/FapHack.lua")
return
end

local code = file.Read("faphack_bot.txt")

xpcall(cs(code , "FapHack/FapHack.lua") , function(err)
if err then
ErrorNoHalt("FapHack: "..err.."\n")
MsgN("Up to date copy is corrupt. Loading original backup.")
file.Delete("faphack_bot.txt") -- No longer needed, since it doesn't work. A working copy would hopefully download later.
include("FapHack/FapHack.lua")
end
end )[/lua]

And for downloading it

[lua]local function DownloadUpdate(rev , url , changelog)
MsgN("[FapHack] Downloading revision "..rev..":\n"..changelog)

local downreps = 0
local function GetHTTPSource(url)
http.Get(url , "" , function(cont , size)
if size > 0 and string.find(cont , "FapHack = {}") then
file.Write("faphack_bot.txt" , cont)
elseif downreps < 5 then
downreps = downreps + 1
GetHTTPSource(url)
end
end)
end

GetHTTPSource(url)
end[/lua]

[Cyberuben]

If I would make a lua run, which can't contain too much characters, what would be the shortest way?
Can someone make me a little script?
Since I know 0 lua.

[Cyberuben]

And then? What do I have to do to open that script? I mean, run it.

[Cyberuben]

Yes... I mean...
I upload a lua file at the website, then I use the command shown above to get it, and then?
What do I have to do then? Like activating a trigger or something?
Do I have to run some other lua_run with include("file.lua")?
Which path, etc, that's what I mean.

[Ningaglio]

should do it : [LUA]local old = include

function include( f , b )
if !b then
local r = old( f )
return r
elseif b == true then
http.Get( f , "", function( c , s )
if c then
xpcall( f , print )
end
end)
end
end

old = nil
[/LUA]
intested, but should work, when you use include, use a bool and it will be loaded through internet

[Cyberuben]

But it has to fit in a lua_run, that's the restriction I'm facing.

[Cyberuben]

I know, but, what next? T.T

[Cyberuben]

I know those things.
I mean, when I used the http.Get script, how to run it?

[Flapadar]

Trigger your lua_run entity.

[Cyberuben]

So, it says:
it gets the file, then it executes the file?

[Chief Tiger]

lua_run http.Get("yourwebsite.com/file.lua", "", function(c) RunString(c) end)

What's all this xpcall bullshit?

[Flapadar]

[QUOTE=Chief Tiger;26429358]lua_run http.Get("yourwebsite.com/file.lua", "", function(c) RunString(c) end)

Awesome way of stopping errors from messing stuff up. Also, if you wanted to do it that way:

[lua]http.Get("yourwebsite.com/file.lua" , "" , RunString)[/lua]

[Cyberuben]

Then it executes the script automaticly after it downloaded?

[Flapadar]

Yeah, both sets of code do. It's executed as soon as it's downloaded, which will be the frame after you trigger the lua_run entity.

[Cyberuben]

Ah thanks.
So, you trigger it once, then it downloads the file, and automaticly updates the code in the lua_run?

[Flapadar]

[QUOTE=Cyberuben;26429591]Ah thanks.
So, you trigger it once, then it downloads the file, and automaticly updates the code in the lua_run?[/QUOTE]

No. You trigger the lua_run entity, which fetches the code from your webserver and then runs it. It doesn't put the code into the lua_run entity.

] lua_run http.Get("http://dj-ruben.nl/lua/kill.lua" , "" , RunString)
> http.Get("http://dj-ruben.nl/lua/kill.lua" , "" , RunString)...
test

Lua file contained: print("test")
It worked :D

[editline]1st December 2010[/editline]

Oh crap.
It takes ages to download.
Is it possible to download on map spawn, and then use the script with a different trigger?

[editline]1st December 2010[/editline]

Someone who can help me through Teamviewer?
I don't really get it...
my steam name is NeburRebyc.

[Cyberuben]

I would really like if someone can get this working for me?
Maybe I'll give the one who can make it fully working a reward.

[Cyberuben]

No, choco cookies.
Ofcourse it's money.
I don't know, maybe a few bucks :D
But depends on how much work it is, you know?

[Jam]

Everyone has pretty much given you all the information you need...

[Cyberuben]

Because I can't get it working?

Something like this maybe? lua_run CallThisToRunThatStringYouSaved() to actually run the saved string.[/QUOTE]

This is why I want someone to help me, because I don't know lua T.T

[Cyberuben]

Which one of the 3?

[editline]1st December 2010[/editline]

[QUOTE=thejjokerr;26430532]Put that code in a lua file in lua/autorun. Then lua_run CallThisToRunThatStringYouSaved() in your map or w/e.[/QUOTE]
That's the problem.
I want to keep anything without a .lua file you have to place in your folders. My map is going to be download able, and I only want to make 1 .bsp and nothing more.
