How to setup Minecraft 1.12.1 on Raspberry Pi 3 [now obsolete and replaced with a successor]

[whyme193]

hello everybody me and my brother just bought RPi 3 b+ with cases, heatsinks, fans and sd cards.Following the tutorial i have managed to get minecraft 1.12.1 running smooth with little to no lag. However the plan was for us to get modded minecraft up and running...

The Pi can barely run Minecraft as it is. Other than mods that make it run faster (Optifine), I think your goals may be too ambitious.

Firstly the way i understand it...

As I recall, copying and pasting that one line was all I needed to do to get 1.12.2 running. I did fiddle with the memory settings near the end of the script to try and get a longer render distance stable, and I managed to get it running at render distance 3, but only at low resolution. Other than that, I didn't play with it much.

I messed around on my Creeper Pie SMP server a bit, just because I could. It was a briefly amusing novelty to play Minecraft on a Pi, on a multi-player server also run on a Pi, but the Raspberry Pi is a really poor client machine for playing the game (works quite well as a server, though).

Good luck, but be sure to manage your expectations, because adding too many mods will likely make the game unplayable.

My modding expectations are very low but it would be nice to add a small amount of light weight mods.
I unistalled minecraft completely restarted. trying for 1.12.2 from the start and using rpiMike's second run script thats already set for 1.12.2 as before it still wont launch but seems to be new error

Code: Select all

However once again if i switch to try and run 1.12.1 it works with no issues 60 FPS and no lag.

I now have minecraft 1.12.2 up and running, I successfully installed forge, I copied Mikesome13's run script and named it runforge1_12_2.sh now I run the .sh in the terminal and

Code: Select all

Maybe there is something i should do prior to starting the run script? idk every step along this set up has given some kind of issues but atleast of already started learning a fair bit about raspian now.
Thanks in advanced for any help.

Look further back in this thread. I'm pretty sure there were others trying to get Forge working, but I don't recall the outcome.

I think something else is missing from Stretch Lite that is stopping the GL driver from working.

Have you got a spare SD Card you can install Stretch with Desktop?

Done what you suggested, but now, Minecraft need permission for me to click play when wanting to download the last bit of data for optifine.

Code: Select all

java.io.FileNotFoundException: /home/pi/.minecraft/versions/1.12.1-OptiFine_HD_U_C5/1.12.1-OptiFine_HD_U_C5.json (Permission non accordée)

Permission non arccordée = Access Denied

EDIT: ok, i definitly had permissions issues on my raspberry pi, that i've fixed by editing them manually i followed the exact setup, and this isn't working anymore

Ok, i get the same issue than before i reflashed the OS, so i guess a kid broke the code, however, i'm wandering if the game is working for the others.

Edit 2 : fixed! I just started again from step 7 to step 11, and it was sucessful!

Apparently, the script will need you to fill the username in order for the script to recover the player's UUID from mojangs servers.

Sometimes i get these errors:

Code: Select all

AL lib: (EE) ALCplaybackAlsa_mixerProc: available update failed: Broken pipe 
AL lib: (EE) ALCplaybackAlsa_mixerProc: mmap commit error: Broken pipe

and my FPS drop to below 1. This occurs randomly and it is really annoying sometimes bc. I have to restart minecraft. I already tried turning down all sounds and using a resource pack without sounds without a result.

I had forge working. I had to try different versions though as it was hard to get mods paired with it.

Before even creating my account I've read this thread over completely at least twice. I'm only making posts because I've done everything mentioned in this thread and it did not yield the same result for me, probably through an error of mine but what error I have no clue. But anyways yes there were others trying to get forge working and they did, Mikesome13 also mentioned it only works with version 1.12.2.

[ZombieTiTan]

When I put the ./runOptifine1_12_1.sh into the terminal this is what I get

Code: Select all

Unrecognized option: --username
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Can someone help. I have found the "--username" is in the runOptifine1_12_1.sh file but I dont know what to do with it. I am really new to this stuff and have no idea what to do. Please Help

[rpiMike]

Did you amend the following with your details without changing the variable names?

MINECRAFT_LOGIN=aaa@bbb.ccc
MINECRAFT_USERNAME=abcdefghi
MINECRAFT_PASSWORD=xxxxxxxx

If you've got any unusual characters you may need double quotes.

I already have, I don't know if I have any unusual characters but I did just to be safe, I found out what I did when you said at the bottom of the whole tutorial

1 Install required version using java -jar Minecraft.jar - and allow to crash
2 Scroll up in terminal window and find last ../jre/bin/java command, scroll across and find ‘-cp ’, copy this path list until ‘ net.minecraft.launchwrapper.Launch’
3 Paste this text into the cp= in the run.sh script

Well I copied the -cp aswell I just deleted that and now it works! Thanks!

[ZombieTiTan]

Hey @rpiMike, I have no idea if @ works but what the heck. Just a quick question what is the latest version of Minecraft running on the pi?

[rpiMike]

The latest version that is currently possible is 1.12.2

1.13 and above requires lwjgl3 which is not available on the Pi - yet

https://github.com/LWJGL/lwjgl3/issues/206

[ancba]

Why i cannot use the last command,it says no permission

[rpiMike]

Do you mean you get permission denied running './runOptifine1_12_1.sh' ?

Did you 'sudo chmod +x runOptifine1_12_1.sh' (end of step 12)

yes ,and I cannot use this command.but I update my system,they can work.thank you

[DarkPlatinum]

I made a post on my site on how to get Forge 1.12.2 working. Thanks for your script rpiMike!

I found the cp path list for 1.14.1 but could not find ‘ net.minecraft.launchwrapper.Launch’ in it so would it be possible for somebody to send me the correct cp ?

[rpiMike]

Not possible unless you can get LWJGL3 compiling for ARM.

Version 1.12.2 is the latest version you can run on a Raspberry Pi.

Even if you could get LWJGL3 compiled for ARM it's highly doubtful newer versions would be playable on a Pi. My budget gaming laptop with a quad-core i7, 16GB RAM and Nvidia GPU is pushed hard playing 1.13.2 or 1.14.1, so I can't imagine our little Pi computers running them at anything more than slideshow frame rates.

[BigrahamLincoln]

every time I try to download glxgears it doesn't work and so in the end on the last step it won't work! please help

[BigrahamLincoln]

what do I do if it says unmet dependancies

[rpiMike]

what do I do if it says unmet dependancies

What says unmet dependancies ?

Did you get glxgears working?

Which Pi are you using? Are you using the latest Raspbian Stretch? Are you using the official power supply? Are you using a 1080p HDMI screen?

https://github.com/LWJGL/lwjgl3/issues/206

This should be working now according to:
https://github.com/LWJGL/lwjgl3/issues/ ... -496018922

I suggest (based on @HawaiianPi comments) that fullscreen 640x480 + kms-full and draw distance of 2 might get you v1.14 playable

Worth a crack just to see if it will run without crashing, even if the FPS is low.

Cheers, and thanks for all the effort put into this thread

[rpiMike]

I have had 1.14.2 running but only lasted about 1 minute before crashing.

1.13.2 seems better: https://www.youtube.com/watch?v=TNCQXd1QzAc

[DarkPlatinum]

1.13.2 still is not effective but is better than nothing. As you can see it shows that the server is lagging when it is "overloaded".
