Question

i'm trying to make a plugin, it must block a specified commands setted by config. i've maked this but it doesn't block any command.

Code:

@EventHandler(priority = EventPriority.HIGHEST)
  public void onPreprocess(PlayerCommandPreprocessEvent event)
  {
    Player player = event.getPlayer();
    String command = event.getMessage();
    List<String> bCmds = this.plugin.cfg.getStringList("blocked-commands");

    for (String bCmd : bCmds) 
    {
        if(command.equalsIgnoreCase(bCmd))
        {
            event.setCancelled(true);
        }
    }
  }

Config:

blocked-commands:
- /pl
- /op
- /sp
- /gravityblock

PS: I've tried to use:

String command = event.getMessage().subString(1);

Thanks for Help... :)

Answer 1

注册活动？实施了清单？

此外，您的代码将无法使用命令中的其他参数。如果它包含空格，则用“”拆分它并获取第一个元素以获取命令

if（cmd.contains（“”））cmd = cmd.split（“”）[0];

如Bukkit's wiiki所述，优先级按以下顺序调用：

EventPriority.LOWEST
EventPriority.LOW
EventPriority.NORMAL
EventPriority.HIGH
EventPriority.HIGHEST
EventPriority.MONITOR

也许您可以尝试使用最低优先级，因此在处理命令之前会取消事件。

我也相信命令可能有参数，所以它可能不等于提供的字符串，你也应该尝试

String command = event.getMessage();


if (command.toLowerCase().startsWith("/command") ) {
    //cancel
}
