做个minecraft kiosk

水鱼拿起尘封已久的树莓派4B干了件大事。创建用户minecraft给到需要的权限(id minecraftuid1001(minecraft) gid1001(minecraft) groups1001(minecraft),46(plugdev),100(users),102(input))创建~/.xinitrc文件给到以下。#!/bin/bash xset s off xset -dpms exec /usr/bin/minecraft-pi-reborn这个就是伪kiosk精髓了开机默认minecraft用户然后开游戏。讲究点加个音效文件记得找libminecraftpe0608.so。其他在树莓派上是不灵光的没有声音。再讲究点加个70元xbox手柄但是自己要写映射键位据说可以不写映射直接玩我是没试成功游戏无响应。#路径是/usr/local/bin/mcpi-pad #!/usr/bin/env bash set -euo pipefail ACTION${1:-} PID_FILE/run/mcpi-pad.pid LOG_FILE/tmp/mcpi-pad.log DAEMON/usr/local/bin/mcpi-pad-daemon.py is_running() { if [[ !
