Hello All! I am a beginner with the Malmo project. I am interested in using it for a user study. Does anyone know what Malmo offers in terms of data collection for multi-player? I'd like to run sessions with multiple players and collect data about people's behavior in Minecraft. I'd appreciate any help you all can give.
Hey everyone, I'm currently working on modifying the eating_1.xml mission sample. I was wondering if there is a way to make my agent keep moving. It stops now and then but that is not nice when you're trying to collect things. I'm sure it has to do with the ContinuousMovementCommands functions but I'm just not exactly sure what to do
Hi all, I'm a student who just came upon this project a few day ago. I've taken a tensorflow for beginner course and I'm wondering if Malmo can be implemented with Tensorflow, just a simple demonstration will do. Specifically, I'm trying to modify tutorial_6 to use tf_agent (https://www.tensorflow.org/agents/overview). This is the closest thing I can find online explaining how to use tensorflow for reinforcement learning. Any help or advice is appreciated.
How hard would it be to create a server version of the Malmo client mod? It would be great to have a hosted server with Malmo agents that users could interact with.

Hey, the "use 1" command in DiscreteMovementCommands is not working for me. Has anyone else faced this problem, and is there any solution to it?

Hello everyone! I am having troubles installing malmo==0.37.0
Where can I find a pip installable wheel?
does project malmo work for Minecraft bedrock edition
Hello, is there a way to pause the Malmo instance until the agent request the next state?
Or, is there a way to slow the game down?

Hi, I just installed Malmo and was wondering if its possible to load an agent to a manually crafted world instead of defining it in XML?
Bhavesh Laddagiri
Also, I wanted to ask can we use Malmo without owning a copy of Minecraft? Because malmo launched a mc forge version and didn't ask me to login or anything like the normal Minecraft. I wanted to know this for a colleague of mine.

@nerdimite Not sure. I just got malmo to build on my fedora box. I'm going to try running in the next hour. If I need to use retail Minecraft (which I have), I think I may need to update the Forge files
Mitch Francis
@nerdimite Looks like it downloads a version bundled with the library. I'd like to use 1.16, and will spend some time to figure it out
@nerdimite I was unable to figure out your first question. You can run Malmo without owning an official copy of Minecraft, though.

hi I want to build a env like MineRL or MalmoEnv , which support chat observation from other agent , I know that the MalmoPython package can support kinds of observation like ObservationFromRay, ObservationFromGrid, ObservationFromChat. But I don't know how can I achieve these information in MalmoEnv or MineRL (gym-like) way, I check the MineRL and MalmoEnv code, I can only find the core.py comm.py related to my question.... can anyone help me here plz?

Hello! I've been trying to use a combination of DiscreteMovementCommands and ContinuousMovementCommands using a deny-list and allow-list which denies a discrete move command and allows a continuous move command. However, when I run a mission, the agent will move forward, but only accept another command (e.g. strafe) occasionally. Other times, it ignores the command and continues to move forward. Here's what the XML looks like:
    <ModifierList type="deny-list">
    <ModifierList type="allow-list">
Hi sorry to bother yall, Im quite new with Malmo and was wondering if anyone ever got this error?

Hello everybody! I'm developing a free Android app that explains computer science and programming concepts and there is a bonus section about AI and I covered some basic ideas about Project Malmo and explained how to install MalmoEnv and to start deploying AI agents that way and I included 2 demo videos, one for trickyarena and one for eating mission. Is it legal (and ok) to cover Project Malmo in an Android app or I need to be affiliated in some way with Microsoft Research Team?

Hey y'all. I'm trying to do a RL project using malmo. I'm teaching the agent to fly an elytra but the jump command doesn't seem to be opening the elytra while he is free falling like it would in normal minecraft. Anyone ever tried to get the agent to fly before?
Does anyone know if this project is still supported? Where did Python_Examples go as discussed here: http://microsoft.github.io/malmo/0.14.0/Python_Examples/Tutorial.pdf?

Hi folks, I'm on an M1 mac which seems to be causing me trouble getting started. I keep running into errors for instance:
java.lang.reflect.InvocationTargetException ..... Caused by: java.lang.UnsatisfiedLinkError: /Users/bennet/.gradle/caches/minecraft/net/minecraft/natives/1.11.2/liblwjgl.dylib: dlopen(/Users/bennet/.gradle/caches/minecraft/net/minecraft/natives/1.11.2/liblwjgl.dylib, 1): no suitable image found. Did find: /Users/bennet/.gradle/caches/minecraft/net/minecraft/natives/1.11.2/liblwjgl.dylib: no matching architecture in universal wrapper
So it looks like I'm missing the correct liblwjgl.dylib file. I've tried replacing it with the newest version that is built for ARM macs but I get the same error. Any ideas? Surely someone has run into this so far :)
Bennet Leff
haha it took me soooo long to get but the trick was to use the x86 version of the azul jdk (v8)
Hey, I am trying to use a custom Small Town map in Minecraft using Malmo but am having a hard time placing items in the map. I wanted to know if it's possible to place items in particular coordinates on the map using Malmo environment?
