LinuxQuestions.org - Minecraft on Stable (Wheezy)

below is a script I used to use
I have commented out ( but not tested ) the ps3 controller bits I used.

essentially has two modes, online and offline

Minecraft.sh

You get the login screen

Minecraft.sh Steve
you play offline , playername Steve ( skips the normal login screen )

Code:

#!/bin/bash

# Minecraft.sh

JavaMem=1024

autokey=autokey-gtk

Minecraft=$HOME/.minecraft

#TODO add some magic to manage .minecraft, plus manage versions and mods



Sixad () {

sudo service bluetooth stop

sudo /etc/init.d/sixad start

}

# Sixaxis Deamon

#ps -e | grep -q sixad || Sixad

#pidof $autokey || coproc $autokey

### above commented out for LQ posting

# sixad is a driver for ps3 controller

# autokey monitors 'events' I use it to map mouse wheel events to the ps3 controller

# ( by mapping 'dead keys' F20 and F21 ) to keys on the PS3Controller.

# when autokey 'sees' these it sends a mouse wheel up/down

then

        # sudo /etc/init.d/sixad start

        # MCUSERNAME=$2

    #else

        MCUSERNAME=$1

    #fi # commented out for LQ post

        # sometimes sixad would 'die' ( if left inactive ) so was just a quick hack to restart it

save as ~/bin/Minecraft.sh
and in terminal

Code:

chmod 700 ~/bin/Minecraft.sh

Minecraft.sh

the chmod is only needed the once, in future just Minecraft.sh [PlayerName]

you might want to tweak JavaMem=1024 ( max 1GB memory, and starts with half (512MB) )
