Hi all,

Ok don't fire me...  does OS/2-ArcaOS have a new enough Java to run Minecraft?

I tried copying the jar file off but couldn't get the syntax to get it to try to run....

Thanks......  We play a lot of Minecraft at our house.  :)

Hi TNG999

Our Java level is 1.6.0_27 (OpenJDK). You can run a "java -version" to check it.  For what I read Minecraft required Java 1.8, but maybe some other components for graphics is required that we may not have ported to ArcaOS.

Regards

Hi

Also there is no Minecraft on the browser (Dooble), because we are missing WebGL.

I found a tutorial..

javaw.exe -jar <minecraftfile.jar>

Gets error "Could not find the main class:  net.minecraft.client.Main.  Program will exit."

Ah well, had to try.  :)

Well, there's a whole bunch of other folders for it on my Windows machine... maybe I'll try copying all of it over and mess around a bit.  Will reply back later.

Perhaps.
Code: [Select]
SET CLASSPATH=
rem adjust to where you have openjdk6 installed
set PATH=x:\openjdk6\bin;%PATH%
javaw -Xmx400M -jar minecraftfile.jar
Also try java instead of javaw. IIRC, Java is case sensitive too.

Edit, added -Xmx400M, might only work with java, not javaw

From personal memory, even the releases of Minecraft which can run under OpenJDK 6 will not start due to the OpenGL requirements.

The only 3D Java game I was ever able to run was Oldschool RS (Version of Runescape from 2007) until they increased the Java requirements a few years back. Keep in mind, that game runs entirely off a software renderer.

Would it be possible to compile and run ClassiCube for OS/2?

I'm working on it.
