Minecraft Spigot插件编码，与Player.send消息有问题

Question

我在编写一个简单的Minecraft 1.10测试插件时，在EclipseJavaMars上收到以下错误：“无法从Command dSender类型对非静态方法sendMessage（String）进行静态引用。”除了主类之外，这是一个单独的命令类。这是整个类：

package io.github.ultraMLGcode.TestPlugin;

import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class TestPluginCommandExecutor implements CommandExecutor {

   public TestPlugin plugin;

   public TestPluginCommandExecutor(TestPlugin instance) {
       plugin = instance;
   }


 public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
    if (cmd.getName().equalsIgnoreCase("basic") && sender instanceof Player) { //If the player typed /basic then do the following...

      if (sender instanceof Player) {
          Player player = (Player) sender;
          //do something
          Player.sendMessage("Hello, it is a nice day, isn't it?");
      } else {
          sender.sendMessage("You must be a player!");
      }

        //doSomething
        return true;
    }
      return false;
    }

}

Answer 1

我不知道minecraft api，但我认为这可以帮助：

更改此行：

Player.sendMessage("Hello, it is a nice day, isn't it?");

到这条线

player.sendMessage("Hello, it is a nice day, isn't it?");

我认为“sendMessage”是一种非静态方法。

我希望这有帮助。
