Please let me bring to your attention the "Red Flower Hell in Minecraft MALMÖ" project. In this page you will find information about our preliminary education and research concept in AGI in Minecraft: http://hackers.inf.unideb.hu:443/RedFlowerHell/

Right now, I am trying to use Malmo on Linux Mint 19.3 with OpenJDK8 using the build-from-source Malmo platform in the latest commit version. When I attempt to run Minecraft with the Malmo mod using

./launchClient.sh -port 10234 -env
I get a message that says [15:13:59] [Realms Notification Availability checker #1/INFO]: Could not authorize you against Realms server: Invalid session id

I think this is preventing my from running missions, because when I try to run tutorial_1.py, nothing happens. There is no error message, but the terminal gets stuck on the command

python3.7 tutorial_1.py

I would greatly appreciate your help in resolving this issue.

Hi, I'm trying to send a command to kill all non player entities: "/kill @e[type=!player]". However, I'm not sure how to send this to the agent, I've tried using agent_host.sendCommand("Chat"+" /kill @e[type=!player]"), but nothing happens. Any advice would be appreciated.

Zachary Wiesenthal

@zwiesenthal

resolved this by adding <ChatCommands/> to xml under agent_handler

Hello everyone can I have some help please

Been trying to set up Malmo for about 2 hours now I can't get ANYTHING to work

I've installed all dependencies, the Minecraft agent is running and everything. But when I run the Java example, It just says

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Malmo\Java_Examples\MalmoJava.dll: Can't find dependent libraries

@ChristopherMillon

Hello everyone, I installed Malmo like so pip install malmo and it now says it's got Malmo 0.37.
But then when I try to run any Python sample, it says it can't find MalmoPython any idea? please

marcus1337

@marcus1337

@ChristopherMillon When I tried malmo I found that the 0.36 worked but not 0.37. However, I did not install it via pip

also I no longer try to use malmo

also remember to have no spacing in any PATHs

Hello everyone! :-)

I get the following error over and over again, when I type launchClient.bat in the terminal:
[...]
:runClient
Error occurred during initialization of VM
Could not reserve enough space for 2097152KB object heap
:runClient FAILED

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':runClient'.

Process 'command 'C:\Program Files (x86)\Java\jdk1.8.0_241\bin\java.exe'' finished with non-zero exit value 1

I have the 64bit Java Version, so having the 32bit is NOT my problem. Do you have any ideas what went wrong?

@ChristopherMillon Instead of importing MalmoPython use: from malmo import MalmoPython.

Hi, does anyone know if there is any way to get all the GUI/Inventory stuff to show up as well from a VideoProducer AgentHandler? thx ;D

Hey!
I'm new to project malmo(I'm a CS student) and I wanted to find out if I can implement my own deep neural network for it to learn how to do stuff(gathering wood, mining blocks etc) but I didn't understand how to actually put my python code into it.(I want to implement my own network and define it's layers/optimizers/loss function etc) Is there any way to do it?

airzocker linux

@airzocker_gitlab

@qwr1000 did you do the included tutorial? because if so you can just copy one of the python scripts, from tutorial 1 or 2 and implement your own code. You can make other scripts with classes and use tensorflow as you would normally and call functions of your tensorflow script to train and get results from your network inside the modified tutorial script ;D

@qwr1000

Hey again! I got it working which it awesome, but I've found another problem. I want to spawn the player with a specific thing in the inventory but I don't know where to get the item names(I know theres "diamond_pickaxe" and "rabbit_stew") are they the normal MC item names, or is there a list of items that Malmo implemented?

Steam365

@Steam3651_twitter

I believe it should be in xsd file

D:\Malmo-0.37.0-Windows-64bit_withBoost_Python3.6\Schemas\types.html

Anyone have any good links for creating an online server using malmo. I'd like to host a server and have users play with an agent I designed to see if it is helpful to them.

marcus1337

@marcus1337

malmö runs on an older version of minecraft, so if you managed to pull that off, then the clients would need to degrade their minecraft

airzocker linux

@airzocker_gitlab

@rohanpaleja27 the main problem I would think is that the malmö mod is a client mod without server version, so i'm pretty sure you can't make a server with the mod, meaning you can't join if you have the mod installed...

Rohan R Paleja

@rohanpaleja27

ah I see, thanks @airzocker_gitlab @marcus1337

Hey, anyone has a quick idea about how to calculate a distance between a block and a player?

marcus1337

@marcus1337

if you have two points in space you can take point A minus point B

and then the absolute value

@decodyng

This might be a somewhat basic question, but: is there a canonical way to use the information returned by ObservationFromGrid, along with the Pitch and Yaw of an agent's viewpoint, to subset the grid observation to those blocks an agent could see from their viewpoint? My understanding is that ObservationFromGrid is returned in absolute orientation rather than orientation with reference to the player's viewpoint, but I can't find documentation for how the array returned from ObservationFromGrid is orientated in terms of N/S/E/W

In part 7 of the tutorial for Malmo: https://microsoft.github.io/malmo/0.17.0/Python_Examples/Tutorial.pdf, They use the curly quotes: o agent_host.sendCommand(“hotbar.9 1”) # press the key
o agent_host.sendCommand(“hotbar.9 0”) # release the key. These quotes cause a compilation errors which can be a very confusing error to figure out. Is there a way to get this fixed? Should I PR this? (All that needs to be done is exchange the curly quotes for the straight ones)

How can I get the position of the agent?
