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:

<DiscreteMovementCommands>
    <ModifierList type="deny-list">
        <command>move</command> 
    </ModifierList>
</DiscreteMovementCommands>
<ContinuousMovementCommands>
    <ModifierList type="allow-list">
        <command>move</command>
    </ModifierList>
</ContinuousMovementCommands>

Hi All, I'm trying to use Malmo but I can't resolve this error:

Could not resolve all dependencies for configuration ':forgeGradleMc'.

Could not find forgeSrc.jar (net.minecraftforge:forgeSrc:1.11.2-13.20.0.2228).
Searched in the following locations:
https://files.minecraftforge.net/maven/net/minecraftforge/forgeSrc/1.11.2-13.20.0.2228/forgeSrc-1.11.2-13.20.0.2228.jar

It seems that the searched jar is no longer available, that url returns 404. How can I solve this? Thank you!!

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 :)

haha it took me soooo long to get but the trick was to use the x86 version of the azul jdk (v8)

brandonmeyer

@brandonmeyer

I'm having a hard time getting 'use 1' to work with discretemovementcommands when I'm trying to use shears. I tried immediately following it with 'use 0', but it seems like discrete 'use' only lets you place blocks. Any tips?

brandonmeyer

@brandonmeyer

I figured it out! I needed a combination of both discrete and continuous commands. Using allow-list/deny-list (i.e. <ContinuousMovementCommands>
<ModifierList type="allow-list">
<command>use</command>
</ModifierList>
</ContinuousMovementCommands>) does the trick

Hey for people still working with Malmo, Ive gotten confirmation with the MineRL mods that Malmo is no longer supported. MineRL is the most up to date fork. Their envs implement the gym methods which is very nice.

can someone help me set up Malmo? I can't seem to get it working. I need Malmo for my research project. Kindly help me. Contact me via discord IrfanFarhat#1233 or email to: irfanfarhatullah@gmail.com. Thank you very much. I need it asap.

does anyone ever use an array of voxel space? (non-visual)

@irfanfarhat MineRL now explicitly supports custom environment creation: https://minerl.readthedocs.io/en/latest/tutorials/custom_environments.html, so use MineRL instead :)

hello everyone! does malmo provide a lower level API? I'm not interested in the mission stuff, I just want an easy way to send commands to minecraft and retrieve video information from it. Is that currently possible or do I have to roll my own solution?
