Bukkit/Spigot - EntityDamageByEntityEvent：投射手

我正在创建一个PvP插件，但我无法继续，因为我有一个令人讨厌的演员问题，我无法解决。我试图让最后损害的原因，则销毁器，检查是否在销毁使用箭，转换“箭头”到射手。但它不断给我在我的控制台的错误。Bukkit/Spigot - EntityDamageByEntityEvent：投射手

因此，这里是我的代码

Player player = (Player)event.getPlayer(); // this variable is in my public void onPlayerMovement event 
if(((EntityDamageByEntityEvent) player.getLastDamageCause()).getDamager() instanceof Arrow) 
{ 
    Arrow arrow = (Arrow) ((EntityDamageByEntityEvent) player.getLastDamageCause()).getDamager(); 
    ProjectileSource shooter = ((ProjectileSource) ((EntityDamageByEntityEvent) player.getLastDamageCause()).getDamager()); 

    if(shooter instanceof Player) // checking if the shooter is a player. 
    { 
     shooter.sendMessage("You hitted someone with a bow right?"); 
     player.sendMessage("You got hit by a bow.."); 
    } 
}

我为什么要箭头转换成射手的原因是因为我想显示一条消息，射手，和几个其他的事情。

这是错误

这可能会或可能无法正常工作，还没有测试它自己。但是在投射之前你需要检查它是否是一个箭头。同样为了获得射手，弹箭类中的方法arrow.getShooter()可以被箭头使用。

if(((EntityDamageByEntityEvent) player.getLastDamageCause()).getDamager() instanceof Arrow) { 
    Arrow arrow = (Arrow) ((EntityDamageByEntityEvent) player.getLastDamageCause()).getDamager(); 
    ProjectileSource shooter = arrow.getShooter(); 

     if(shooter instanceof Player) // checking if the shooter is a player. 
     { 
      Player shooterPlayer = (Player) shooter; 
      shooterPlayer.sendMessage("You hitted someone with a bow right?"); 
      player.sendMessage("You got hit by a bow.."); 
     } 
}

如果没有帮助，请让我知道第102行是什么。

第102行：玩家damager =（玩家）entitydamager; –

当玩家的Y <= 10时，这条线被称为 –

我添加了ProjectileSource射手= arrow.getShooter（）;但是当我尝试使用这个时它给了我一个错误：shooter.sendmessage（）;.它说：“sendMessage（String）方法未定义类型ProjectileSource”。 –

以下是测试解决方案的摘录，以通知玩家彼此互相射击。这应该可以帮助你。

@EventHandler 
public void onEntityDamageByEntity(EntityDamageByEntityEvent evt) { 
    // Is target a player, if not stop 
    if (!(evt.getEntity() instanceof Player)) 
     return; 

    Player damagee = (Player) evt.getEntity(); 

    // Is damager an arrow, if not stop 
    if (!(evt.getDamager() instanceof Arrow)) 
     return; 

    // Is shooter a player, if not stop 
    ProjectileSource src = ((Arrow) evt.getDamager()).getShooter(); 
    if (!(src instanceof Player)) 
     return; 

    Player damager = (Player) src; 
    damager.sendMessage("You just shot " + damagee.getName()); 
    damagee.sendMessage("You were shot by " + damager.getName()); 
}
