Fun and Games with Minecraft on ARM

[moocow1452]

So I've been trying for a while yet to run a full PC version of Minecraft on a SoC board like the Beaglebone Black or the Raspberry Pi, with the intention of making it into a portable build, so GLShim is an awfully useful project in that regard. I've seen video of it running on an Open Pandora, so I know that certain builds of certain versions of Minecraft can run, but can this functionality be ported to a more generic ARM board, or even allow for GLShim equipped application-ports for Android?

PS: Most recent run on a LWJGL-patched Pi. Same or similar error message ran when I tried to run it on my Beaglebone Black, so that's promising.

The minecraft video uses ptitseb's glshim fork. It's slow enough on a Pandora - you probably won't get very good framerate on a Pi. Have you seen Minecraft Pi Edition?

glshim is definitely useful for ports to mobile phones/tablets. I have a medium-term goal to come up with some demos there. The hard part isn't actually OpenGL anymore. It's the other pieces: X11, ALSA, etc. It's totally feasible on games already using SDL, which is how the GCW Zero glshim fork works.

(My current project is actually a software GL ES backend for glshim so slow 2D games like Uplink and Aquaria will be much faster. I have Uplink from 2-20fps on a Pandora up to 60-80fps.)

Have you seen Minecraft Pi Edition?

Yeah, but it hasn't been updated in a forever and a half, so I figured I might as well try and get the full PC version running on ARM, since Java is supposed to be able to run everywhere, and fragmentation of Minecraft across the different "editions" make cross-world travel a pain. Also mostly because I have to do something with my time, and video games aren't cutting it as much as they used to.

This is my latest error log from running on the Bone, and again, Pi is similar enough that a fix across one would probably fix the other. Got any idea how to contact ptitseb, insights, or point me in a direction where I can don't have to bug you every time I wanna run something new?

You might have success messaging ptitseb on the OpenPandora forums.

K. After running his build for a bit, I ran into a point where we were both stumped. Error log as follows...

Any idea what could cause Java to completely crap the bed? On Jul 1, 2014 9:01 PM, "Ryan Hileman" notifications@github.com wrote:

That's more of a java question than a glshim question.

You can dig into it further with gdb, valgrind, etc or any java debugging programs.

Also keep in mind Ptitseb's glshim fork has a ton of overall changes so I'm not going to be of much use helping you with it.

try the full-blown Mesa for VC4 driver.

[Epica-Lolz]

Well, here's the issue with that: The Mesa driver is OpenGL, and typically, most arm machines/boards come with OpenGLES, which is a special version of OpenGL designed for phones/tablets. To compensate for that, they made glshim, which is something that translates OpenGLES to regular OpenGL (Albeit, an older version of OpenGL.)

@moocow1452: Zhuowei Zhang has already done this, it's called Boardwalk, and you can find it in the Play store.

[lunixbochs]

Boardwalk uses glshim. This is a thread about the Raspberry Pi, not Android. There's also a working Pandora version of Minecraft.

[lunixbochs]

You should try again on the latest unstable glshim (which has much better Pi support).
