Minecraft 插件前缀 (Java)

Question

我只想为 minecraft 服务器创建简单的前缀插件，它会在聊天框中显示每个玩家的点数。

我使用的 API = PlayerPoints & Spigot 1.9.4 阴影。关于 PlayerPoints API : Click here

作为控制台显示问题出现在 PlayerListener.java:

package points.prefix;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.black_ixx.playerpoints.PlayerPoints;


public class PlayerListener implements Listener {

Main plugin;
public PlayerListener(Main instance){
     this.plugin = instance;
}  

public PlayerPoints getPlayerPoints() {
    return getPlayerPoints();
}

//OnPlayer Join
@EventHandler
public void playerjoin(PlayerJoinEvent e){
    Player p = e.getPlayer();
    String pname = p.getName();
    int points = getPlayerPoints().getAPI().look("Player");

    //Begin
    if (p.hasPermission("prefix.point")){
        String member = "" + ChatColor.WHITE + "[" + ChatColor.GREEN + points + ChatColor.WHITE + "]" + ChatColor.RESET + ChatColor.WHITE + pname + ChatColor.RESET + "";
        p.setDisplayName(member);
    }
} }

来自 spigot 控制台的错误日志：

points.prefix.PlayerListener.getPlayerPoints(PlayerListener.java:19) ~[?:?] [20:57:40]

来自 eclipse 的错误日志：

The method look(String) from the type PlayerPointsAPI is deprecated

这是另一条注意事项：在 PlayerpointsAPI 页面中提到使用：

int balance = playerPoints.getAPI().look("Player");

显示平衡！但它不起作用！

有人知道怎么回事吗？

谢谢你

以后请让人们知道您的错误是什么以及它在哪一行。在这种情况下，您会遇到堆栈溢出错误，因为您的 getPlayerPoints 方法会递归调用自身，而实际上却没有做任何事情来跳出无限循环！

您链接的页面准确地告诉了您缺少的内容。它说 "During enable, you need to grab the PlayerPoints plugin instance and save that reference somewhere as you will be using the API through it."

因此，使用他们提供的示例代码（为简单起见复制到此处）：将这两个方法复制到您的插件 class（在您的情况下可能是 Main.java）并更改 getPlayerPoints( ) 方法在你的侦听器中到 plugin.getPlayerPoints()。或者，如果您的侦听器中的其他任何地方都没有使用该插件，您可以只在构造函数中引用 playerPoints 实例，而不是引用您的插件。

private PlayerPoints playerPoints;

/**
 * Validate that we have access to PlayerPoints
 *
 * @return True if we have PlayerPoints, else false.
 */
private boolean hookPlayerPoints() {
    final Plugin plugin = this.getServer().getPluginManager().getPlugin("PlayerPoints");
    playerPoints = PlayerPoints.class.cast(plugin);
    return playerPoints != null; 
}

/**
 * Accessor for other parts of your plugin to retrieve PlayerPoints.
 *
 * @return PlayerPoints plugin instance
 */
public PlayerPoints getPlayerPoints() {
    return playerPoints;
}
