[Mod] Raspberry PI MC API for Python code [raspberryjammod]

[cvincross]

have you added "secure.enable_security = true" to your minetest.conf? That is what fixed that error for me.

@jocsamazon
I would like to know what specific changes you made in order to run minetest with raspberryjammod?
I am running Windows 10, Minetest 0.4.17.1 and Python 3.6.5.
I have replaced the mcpipy files as you indicated in your post quoted above, but the mod fails to load with the following error, and as a result, I cannot even test the Python scripts.
So how do I fix this error and proceed

add this to minetest.conf:

Code: Select all

secure.trusted_mods = raspberryjammod

have you added "secure.enable_security = true" to your minetest.conf? That is what fixed that error for me.

Don't touch this setting! Mod security should never be disabled

My mistake...so specifying this as "true" worked on one machine (oddly)... on another machine it only works with security disabled... which is a BAD idea for sure... but with security enabled I get a "require() is disabled" message. any ideas how to get around that?

This is on the latest 5.0.0dev on linux.

Again...my mistake... I just confirmed I can't get either machine to work with security turned on... so both return the error about require() being disabled by security. Any help would be appreciated. Does turning off security pose a serious security risk if it is being used as a self hosted single player session - ie without the server enabled?

You need to change `require` this:

Code: Select all

local old_require = require
require = ie.require

local socket = require("socket")
-- any other sockets

require = old_require

require = old_require

Ok, I am probably doing this wrong... but I made the above change to the init.lua of the mod and I'm not getting it to work. Am I wrapping just the socket "requires" with this redefinition or all of them? - there are three others that are not "sockets" sprinkled throughout the script. I'm not really clear on what this is accomplishing though...since the calls are already ie.require before I redefine require to be ie.require. please excuse my ignorance. Anyway... when I do this I end up with an error about attempting to index a nil value for "ie" - the same error I get if I don't include the mod in secure.trusted_mods

[Can't connect to server--SOLVED]
Hi, I am trying to apply this great mod to python programming education, and I think I would be fun with multi-player.
I have tested this mod on linux Ubuntu 18.04 with single-player and multi-player on the same machine.
But I have some problem with multi-player on different machines. I have a PC and a laptop both running Ubuntu 18.04 and both can run this mod in single-player mode.
Now I have PC as server and laptop as client, laptop can connect to server and play the game, but cannot use the mcpi api to connect to server.
If I enter the following in the laptop python ternimal:

Code: Select all

mc = Minecraft(connection=Connection("192.168.1.90",30000))    # try connecting to server

I get an error:

Code: Select all

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "connection.py", line 37, in __init__
    self.socket.connect((address, port))
  File "/usr/lib/python2.7/socket.py", line 228, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 111] Connection refused

Is there anything I have done wrong? Dose anyone successfully tried this mod on different machines playing multi-player?

Oh, forgot to mention, I using Minetest 0.4.16, lua5.1


----------------
[edit]:
now I have solved the above problem:

Code: Select all

mc = Minecraft(connection=Connection("192.168.1.90",30000)) 
# this is wrong way to connect to the api server, which is on a defferent port(default to 4711) than the minetest server

the right way is to set

Code: Select all

restrict_to_local_connections = false

in the settings.conf file(already set to false by default)
and do this on the client terminal:

Code: Select all

export MINECRAFT_API_HOST='your server address'
export MINECRAFT_PLAYER_NAME='your player name'

notice:
there are some differences between the links below, I don't know which is newer. my test is done with git cloning the 2nd link, and extracted the raspberryjammod folder. exporting MINECRAFT_PLAYER_NAME in ternimal might not be working with the source code in the 1st link.
https://github.com/arpruss/raspberryjam ... t/releases
https://github.com/arpruss/raspberryjammod-minetest

now It is fully functional even in multi-player mode on linux(ubuntu)! thanks again to the author!

Don't touch this setting! Mod security should never be disabled

Still getting the le nil value error. Using 0.4.17

doesn't work for me either, so I just set security to false

[zargulthewizard]

That fixes it?

[hyan]

That fixes it?

yes

[zargulthewizard]

Well...

Don't touch this setting! Mod security should never be disabled

I don't really play online...

Mod security should never be disabled

Or use any really risky mods...

never be disabled

[zargulthewizard]

I disabled it. The good news is the ie nil value error is gone. The bad news is during server creation Minetest crashed completely with no error report or anything.

Anyone could explain how to install this mod on debian buster?
Thank you

Thank you

Just drop in ".minetest/mods" the folder https://github.com/arpruss/raspberryjam ... erryjammod

Then you need to activate it in your world mods config.

I have installed it in Fedora 32 and it is working nicely (at least the API that I have needed). I have needed to install the package "lua-socket-compat.x86_64" so this Lua 5.1 code runs in the 5.3 version that comes with Fedora 32. Good luck!

Bro I'm a complete noob, I can't understand how to install this and run Python scripts.
Can you guide me?

[zargulthewizard]

I know python, and I couldn't get it to run at all, which was disappointing. :(
