问题描述
这只是我的第二个问题，因此，如果我做错任何事情，请多包涵。
我一直在编码一个Bukkit插件，其中包括一个辐射效果，如果您不在指定的安全区域内，则会受到损坏。我正在使用WorldEdit API来指定上述区域，但是在实现破坏效果本身之后，现在接收到空指针。
这是辐射等级：
package com.psychoticatt.outerrimcore;
import java.util.HashMap;
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Location;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerMoveEvent;
import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;
import com.psychoticatt.outerrimcore.events.PlayerIrradiatedEvent;
import com.sk89q.worldedit.bukkit.BukkitAdapter;
import com.sk89q.worldedit.math.BlockVector3;
import com.sk89q.worldedit.regions.CuboidRegion;
import com.sk89q.worldedit.world.World;
public class Radiation implements Listener {
public org.bukkit.World waste = Bukkit.getServer().getWorld("wasteland");
public World w = BukkitAdapter.adapt(waste);
Location loc1 = new Location(waste,207,3,124);
Location loc2 = new Location(waste,226,23,143);
BlockVector3 vect1 = BukkitAdapter.asBlockVector(loc1);
BlockVector3 vect2 = BukkitAdapter.asBlockVector(loc2);
CuboidRegion cRegion1 = new CuboidRegion(w,vect1,vect2);
PotionEffect rStage1 = new PotionEffect(PotionEffectType.WITHER,1,10000,false,true);
PotionEffect rStage2 = new PotionEffect(PotionEffectType.WITHER,2,1000000,true);
HashMap<Player,Boolean> radStatus = new HashMap<Player,Boolean>();
@EventHandler
public void onPlayerMove(PlayerMoveEvent e) {
Player p = (Player) e.getPlayer();
BlockVector3 to = BukkitAdapter.asBlockVector(e.getTo());
BlockVector3 from = BukkitAdapter.asBlockVector(e.getFrom());
if(cRegion1.contains(to) && !cRegion1.contains(from)) {
p.sendMessage(ChatColor.AQUA + "Entering Safezone!");
PlayerIrradiatedEvent isIrradiated = new PlayerIrradiatedEvent(p,false);
Bukkit.getServer().getPluginManager().callEvent(isIrradiated);
} else if(!cRegion1.contains(to) && cRegion1.contains(from)) {
p.sendMessage(ChatColor.RED + "Exiting Safezone,You Are Exposed To " + ChatColor.GREEN + "Radiation!");
PlayerIrradiatedEvent isIrradiated = new PlayerIrradiatedEvent(p,true);
Bukkit.getServer().getPluginManager().callEvent(isIrradiated);
}
}
@EventHandler
public void onPlayerJoin(PlayerJoinEvent e) {
Player p = (Player) e.getPlayer();
radStatus.put(p,false);
}
@EventHandler
public void onIrradiated(PlayerIrradiatedEvent e) throws InterruptedException {
Player p = (Player) e.getPlayer();
Boolean s = e.getStatus();
if(radStatus.containsKey(p)) {
radStatus.replace(p,s);
if(radStatus.get(p).equals(true)) {
p.addPotionEffect(rStage1);
Thread.sleep(10000);
p.addPotionEffect(rStage2);
} else {
p.removePotionEffect(PotionEffectType.WITHER);
}
}
}
}
这是我引用的自定义事件：
package com.psychoticatt.outerrimcore.events;
import org.bukkit.entity.Player;
import org.bukkit.event.Event;
import org.bukkit.event.HandlerList;
public class PlayerIrradiatedEvent extends Event {
private Player player;
private Boolean status;
public PlayerIrradiatedEvent(Player p,boolean b) {
player = p;
status = b;
}
public Boolean getStatus() {
return status;
}
public Player getPlayer() {
return player;
}
public HandlerList getHandlers() {
return null;
}
}
我的主班：
package com.psychoticatt.outerrimcore;
import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin {
public void onEnable() {
this.getServer().getLogger().info("[OuterRimCore] Works!");
Bukkit.getServer().getPluginManager().registerEvents(new Radiation(),this);
}
}
这是错误日志：

任何帮助将不胜感激，因为我似乎无法在其他任何地方找到解决方案。
解决方法
我知道了！
事实证明，我的自定义事件类不完整，并且未设置为返回事件处理程序。所以我主类中的onEnable（）方法试图获取所有事件处理程序，并为其中一个获取空值。
我在这里包括了更新的代码：
Traceback (most recent call last):
File "C:/Users/Softech/Desktop/tkinterproject.py",line 29,in <module>
reg=Button(home,text="Register",bg='brown',fg='white',width=20,command=regc)
NameError: name 'regc' is not defined
感谢大家如此迅速的答复，您帮助我走上了正轨！
