Issue spawning HumanEntity

New Problem:

Code:

public class Generals extends JavaPlugin {
public void onEnable() {
//
}
public void onDisable() {
//
}
public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
Player player = null;
if (sender instanceof Player) {
player = (Player) sender;
}
if(cmd.getName().equalsIgnoreCase("spawnnpc") && (player != null)) {
WorldServer ws = getWorldServer(player.getWorld());
Human hTest = new Human(getMinecraftServer(player.getServer()), ws, "Bob", new ItemInWorldManager(ws), player.getLocation());
return true;
}
return false; 
}
private static WorldServer getWorldServer(World world) {
        return ((CraftWorld) world).getHandle();
    }
    private static MinecraftServer getMinecraftServer(Server server) {
        return ((CraftServer) server).getServer();
    }
}

Code:

public class Human extends EntityPlayer {
public Human(MinecraftServer msServer, World wTargetWorld, String s,
ItemInWorldManager iwmItemManager, Location loc) {
super(msServer, wTargetWorld, s, iwmItemManager);
iwmItemManager.setGameMode(0);
this.setPosition(loc.getX(), loc.getY(), loc.getZ());
wTargetWorld.addEntity(this);
wTargetWorld.players.remove(this);
}
 
}

And I get this error when I /spawnnpc although the NPC called "Bob" does appear inside the server (and the server stops running).

Code:

Any help about why the error happens is appreciated.

 

Try and put the plyer.getServer() between parenthesis to do the cast, that might help

 

Okay I'll give it a shot
Edit: Tried putting brackets around all the (xx)player.__() casts and it didn't help.

-- Bump --

Got it working, but there is a new problem now.
