java - CraftBukkit 插件编码错误

Question

我正在为 CraftBukkit Beta Build 1.7.2 R0.3 制作一个简单的 /heal Bukkit 插件。 (我是 java 的新手。)我在 Eclipse 中编程。我收到一条错误消息:

这是我的代码:

public boolean onCommand_heal(CommandSender sender, Command cmd, String commandLabel, String[] args){
    Player player = (Player) sender;
    if(commandLabel.equalsIgnoreCase("heal")){
        if(args.length == 0){
        player.setHealth(20);
        player.setFireTicks(0);
        player.sendMessage(ChatColor.GOLD + "You are healed!"); 
        }else if(args.length == 1){
            if(player.getServer().getPlayer(args[0]) !=null){
                Player targetPlayer = player.getServer().getPlayer(args[0]);
                targetPlayer.setHealth(20);
                player.sendMessage(ChatColor.GOLD + "Player Healed!");
            }else{
                player.sendMessage(ChatColor.RED + "PLAYER NOT ONLINE!");
            }
        }
    }
    return false;
}

Answer 1

尝试这样做:

Player targetPlayer = Bukkit.getServer().getPlayer(args[0]);
//or this:
Player targetPlayer = plugin.getServer().getPlayer(args[0]);

代替

Player targetPlayer = player.getServer().getPlayer(args[0]);

和这里一样，替换:

if(player.getServer().getPlayer(args[0]) !=null){

与:

if(Bukkit.getServer().getPlayer(args[0]) != null){

此外，自最近的 Bukkit 更新以来，您应该始终在设置健康时使用 floats。 setHealth(int) 已弃用，取而代之的是 setHealth(float)，因此请尝试:

targetPlayer.setHealth(20.0f);
