    hello, I am making an Anti-Spam plugin.
    The problem:
    When people chat they get added to the "antispam ArrayList" but the never get removed. I also get an error when people chat.

    - Sheep

    AntiSpam Class:
    Code:java
    1. package me.theholysheepnl.ServerHelp;
    2.  
    3.  
    4. import java.util.ArrayList;
    5.  
    6. import org.bukkit.Bukkit;
    7. import org.bukkit.ChatColor;
    8. import org.bukkit.entity.Player;
    9. import org.bukkit.event.EventHandler;
    10. import org.bukkit.event.EventPriority;
    11. import org.bukkit.event.Listener;
    12. import org.bukkit.plugin.Plugin;
    13.  
    14. public class AntiSpam implements Listener {
    15.  
    16.       ArrayList<String> antispam = new ArrayList<String>();
    17.  
    18.     @EventHandler(priority = EventPriority.NORMAL)
    19.     public void onChatEvent(final org.bukkit.event.player.AsyncPlayerChatEvent e){
    20.         final Player p = e.getPlayer();
    21.         if(antispam.contains(e.getPlayer().getName())){
    22.         p.sendMessage(ChatColor.RED + "You have to wait" + ChatColor.GOLD + " 2 " + ChatColor.RED + "More seconds before you can send a message again!");
    23.         e.setCancelled(true);
    24.         return;
    25.         }
    26.         if(!antispam.contains(e.getPlayer().getName())){
    27.         antispam.add(p.getName());
    28.         Bukkit.getServer().getScheduler().scheduleSyncDelayedTask((Plugin) this, new Runnable() {
    29.             public void run() {
    30.             antispam.remove(e.getPlayer().getName());
    31.             }
    32.         }, 20);
    33. }
    34. }
    35. }

    You cannot cast AntiSpam to Plugin. Because the class AntiSpam doesn't extend JavaPlugin class.

    (Plugin)this
    AntiSpam is not an instance of Plugin.

    Do you understand how to read stack traces?
    They literally tell you where the error is.

    EDIT: Ninja'd

    Get the plugin instance. Put a static method in the main class that gets the plugin instance.
    You will need a static variable of type Plugin for this.

    Code:
    private static Plugin plugin;
public void onEnable(){
  plugin=this;
}
public static Plugin getPlugin(){
  return plugin;
}

    Zwander That is in his main class.

    TheHolySheep_NL Please learn Java first. Otherwise, you'll keep having issues like this and won't know how to do them.

    Yea, I know... Was about to point that out. Its actually in the right place, he/she has just cut off the rest of their onEnable by the looks of it...
