[QUOTE=Pecius;31189065]You forgot to put error handlers on script loading!

Put them both for Java equivalents of lua_pcall and luaL_loadfile/lua_load.[/QUOTE]

I dont understand what you mean? Script loading is error handled as are the pcalls and the loadfiles.

[QUOTE=Saccn;31189166][lua]
function OnScriptStart()
Server.AddHook( "player.connect", "OnPlayerConnect" )
end[/lua][/QUOTE]

Ah. If you have a look at the wiki at the Server.AddHook function you should notice that with the latest version theres a third parameter. You need to pass the name of your script as a third parameter.

[Saccn]

Oh. Now it works.

[Genesis999]

[QUOTE=Saccn;31189211]Oh. Now it works.[/QUOTE]

Glad that it wasnt me screwing up the behind the scenes code. :)
Cause that happens quite a lot. :P

Strange, because it's not printing any errors in console on start when I'm running a code with syntax/runtime errors.

What code you trying to run?

[Pecius]

[QUOTE=Genesis999;31189311]What code you trying to run?[/QUOTE]

Um, any bad code such as

[lua]How did I get here I'm not good with computers[/lua]

or

[lua]string.sub(false, 1, 1)[/lua]

It just doesn't give any errors about this.

[Saccn]

The console is printing out "[WARNING] LUA: Error at OnPlayerPlaceBlock" when I right click with an empty hand. It's nothing game breaking, but it should be fixed anyway.

[editline]18th July 2011[/editline]

Also, can you make TeleportTo() not change the angle at which the player is looking at?

[Saccn]

Can you make all timers stop when you reload a script without restarting the server?

Damn automerge.

[Se1f_Distruct]

Couldn't get it to work, the lib name was supposed to be luajava-1.1.dll, not luajava-1.1-x86.dll

When I got it to work, it worked amazingly!

Please keep this going, as I believe it has more potential than bukkit!

[QUOTE=ruarai;31205404]If you make a SP version allow the clients and servers to communicate both using luaserver and luaclient[/QUOTE]

When I do make a SP version that will definitely be on the list of features. :P

[Genesis999]

Okay my lovely facepunchers.

Another day has passed by and at the end of it after much head scratching Ive gone and version up'ped. :)

Rewrote the player.placeblock hook code so that it works better and neater.
Rewrote the Sql.SelectFromTable function code, now hell easier to get your results.
Moved all the global SQL functions inside a global "Sql" object for neatness.
Renamed global "PropertyManager" to "Files" to facilitate later updates.
Renamed property file functions
Reworked the PrintToChat function a little
Timers reload when the script reloads
Commands require the scriptname being passed in as a third parameter.

Note: It'd be best to get a clean minecraft_server.jar as otherwise things could get messy as I have also done some cleaning. :)
Second note: In advance for when you curse my name for changing the PrintToChat parameters order around a bit im sorry but i felt it was necessary to make things better. :)

I told you to put error handlers BOTH for script loading and script executing functions.
You didn't put anything that would receive loader's result and stop from further operations.

Right now, when there's a syntax error, user doesn't receive any useful information, only this:
[img]http://i51.tinypic.com/20u3nlc.png[/img]

[editline]0[/editline]

And "attempt to call a string value" message is printed, because loader pushed string with error message at top of the stack.

Uhm how would I go about running the .jar file as 32bit? (since I'm on 64bit Win7)

Did you not get my PM, Genesis?

I'd PM you on the mincraft forums, but it's not letting me create an account. I made an account before they switched to Curse, and now it says my email is in use, but when I try to log on using my old account details, it says that logon doesn't exist.

Mmm. Bugs. I threw up a new version that fixes that and some more little changes.

[Saccn]

Why is the console always writing "[WARNING] LUA: Error handling command." when I enter a command? The command executes properly, so I don't see what's the problem.

[QUOTE=Saccn;31224837]Why is the console always writing "[WARNING] LUA: Error handling command." when I enter a command? The command executes properly, so I don't see what's the problem.[/QUOTE]

Is this from the console that its doing that?

EDIT: Also I should mention that along with the fix of the place block thing i also changed a lot of the objects GetUser to return a player object and added a GetUsername to return just the name.

[Saccn]

Client and console.

[Genesis999]

[QUOTE=Saccn;31224926]Client and console.[/QUOTE]

Ive just been experimenting. It seems that if you dont use Command:SetReturn(255) that it says there was an error. :S weird

[Divran]

Discussing vectors

12:55 - Divran: you should remove GetPositionX, GetPositionY, and GetPositionZ
12:55 - Divran: and replace it with GetPos or GetPosition
12:56 - Divran: which would return a table looking either like this {x,y,z} (number indexes) or like this {x=x,y=y,z=z} (string indexes)
12:56 - Divran: and then make SetPosition accept that table (Or 3 numbers, too, maybe)
12:56 - Divran: Or you could even make a Vector class
12:57 - thegenesis999: Yea. Im going to bunch them up some way soon.
12:57 - Divran: a vector class would be very useful if you gave it functions such as rotate

Discussing the use of classes all over the place

01:03 - Divran: this one thing I noticed that was really strange
01:03 - Divran: SetReturn(255) whats up with that
01:04 - Divran: the command hook should just send
player, rawtext, table with exploded text
01:04 - Divran: as its arguments
01:04 - Divran: no need to use an entire class to do it
01:04 - Divran: Same thing with the chat hook
01:05 - thegenesis999: Yea. Using a class for it does simplify some things though.
01:05 - Divran: what things
01:06 - thegenesis999: well...
01:07 - thegenesis999: the backcode for one

Discussing the removal of RegisterCommand & the adding of the command hook

01:07 - Divran: Why do you have a function called RegisterCommand when you already have a command hook
01:08 - thegenesis999: what do you mean?
01:08 - Divran: you only need the hook
01:08 - Divran: oh wait
01:08 - Divran: you removed the command hook
01:09 - thegenesis999: by command hook do you mean the CommandHandler function?
01:09 - Divran: yes
01:09 - Divran: you dont have functions for that anymore
01:09 - Divran: remember
01:09 - thegenesis999: Yea i removed that. :P
01:09 - Divran: you use hooks now
01:09 - Divran: so I call it hooks
01:10 - Divran: why do you not use your hook system, then?
01:10 - Divran: its perfect for this
01:10 - thegenesis999: hold on. ive lost track of what this is.
01:10 - Divran: a command hook called whenever anyone types /something
01:11 - Divran: actually you could just as easily use the chat hook for it
01:11 - thegenesis999: i like the seperation of commands from hooks. it feels neater.
01:11 - Divran: but then it wouldnt work if the console types /something
01:11 - Divran: no it doesnt
01:12 - thegenesis999: well it does for me.
01:12 - Divran: then you have to spam RegisterCommand
01:12 - thegenesis999: :)
01:12 - Divran: if I were to make an admin mod
01:12 - Divran: I would now be forced to spam RegisterCommands which all called the same function
01:12 - Divran: just to make it work like hooks
01:13 - Divran: because otherwise my Lua code would be ugly as fuck
01:13 - Divran: because I would store my command functions in a table
01:13 - Divran: Wait
01:13 - Divran: let me explain how Id do it
01:13 - Divran: First I would make a table to store all the commands
01:14 - thegenesis999: so im guessing you feel one big function is better than a lot of little ones?
01:14 - Divran: Then I would store each command similar to this
Commands = {}
Commands["tp"] = { Allowed = { "op", "admin", "superadmin", "whatever other rank" }, Function = function() something end }
01:14 - Divran: And then I would need a hook to check if that command existed in the table
01:15 - Divran: And compare ranks to see if the user is allowed to use it
01:15 - Divran: else print error
01:15 - Divran: 01:14 - thegenesis999: so im guessing you feel one big function is better than a lot of little ones?
Yes.
01:15 - thegenesis999: mmk
01:16 - Divran: because 99.99% of the times, when making commands such as this, you want to make the exact same comparisons for every single command
01:16 - Divran: before running its unique function
01:16 - Divran: such as allowances
01:16 - Divran: and maybe if the owner of the server disabled it
01:16 - Divran: if your mod supports command disabling
01:16 - Divran: the list goes on
01:18 - thegenesis999: hmmm
01:21 - Divran: going to post some of our discussion on FP
01:21 - thegenesis999: ok then
01:22 - thegenesis999: so you want something like the old command hook back?
01:22 - Divran: yep

What do you guys think?

[LuaStoned]

[QUOTE=Divran;31225528]What do you guys think?[/QUOTE]

I can just agree, the whole project started nice and small but right now it's kind of messy.
I was even thinking of writing a wrapper class to make the lua part act like it does in GMod..

€dit: Like this:

[lua]-- i'm assuming that you did this...
GetUser()
GetUsername()
-- ... so why create another global function when you can do this instead
(player obj):GetName()

The getuser and getusername functions arent global functions.

In fact there are only two global functions ( PrintToChat and PrintToConsole) and three global variables(Server, Files and Sql).

[Saccn]

I can't get Chat:GetName() to work anymore.

[lua]
function OnScriptStart()
Server.AddHook( "game.chat", "OnPlayerChat", "Test" )
end

function OnPlayerChat( Chat )
PrintToChat( Chat:GetName()..": "..Chat:GetMessage(), 15, "#all" )
Chat:SetReturn( 255 )
end
[/lua]

This works if I take it out.

[b]Edit:[/b]

Nevermind. Found out how to make this work.

[Divran]

[QUOTE=The-Stone;31087749][lua]

table.insert(files, line:match("[%d%p]%s([%w%p]+)"))

table.remove(files, #files)
table.remove(files, #files)

return files

Thanks, but that doesn't work. io.popen returns nil no matter what file path I give it.

[Genesis999]

[QUOTE=Divran;31230989]Thanks, but that doesn't work. io.popen returns nil no matter what file path I give it.[/QUOTE]

That'd could be because in the latest version I dont make the call to open the io.
