Question

我正在尝试创建和＆＃34; IDE＆＃34;对于我的世界命令。我试图实现命令自动完成，但我无法弄清楚如何做到这一点。尝试使用bukkit：

// Example command
String fullCommand = "fill 3 ";

        String command = "";
        List<String> argList = new ArrayList<>();
        for (String string : fullCommand.split(" ")) {
            if (command == "") {
                command = string;
            } else {
                argList.add(string);
            }
        }
        Command cmd = new Command(command) {

            @Override
            public boolean execute(CommandSender arg0, String arg1, String[] arg2) {
                return false;
            }
        };
        System.out.println(command);
        TabCompleter tabCompleter = getCommand(command).getTabCompleter();
        tabCompleter.onTabComplete(Bukkit.getConsoleSender(), cmd, command, argList.toArray(new String[0]));

我收到以下错误：

在bukkit，forge或其他方面有没有办法解决这个问题？

Answer 1

尝试改变：

TabCompleter tabCompleter = getCommand(command).getTabCompleter();

到

getCommand(command).setTabCompleter(new TabCompleter() {

    @Override
    public List<String> onTabComplete(Sender s, Command cmd, String label, String[] args) {
        if(s instanceof ConsoleSender && cmd.equalsIgnoreCase("fill") {
            return argList;
        }
    } 
});

同时删除最后一行。

(Picture of error) try:

您正在获取Null指针，请确保plugin.yml位于src之外。还要确保没有错误！而你应该没事。这也取决于你使用的插口/ bukkit罐子。 1.9+已经重命名了很多！

Minecraft自动完成
