[help] Craftbukkit 1.7.9 won't allow casting of sender to player?

So, I was remaking a small explosive projectiles plugin that I've already done once (private plugin).
I was making some commands -- /bow, /snowballs, /egg -- that would give you some materials to, y'know, shoot and blow up stuff. I have it so that if the console tries to issue any of the commands, it sends back a message. *Quick edit* The message worked before, but now it wont, for some reason.
Anyway, to the point, the console says this:

Code:

>egg

Here's my Initial class:

    }

        Player player = (Player) sender;
 
        if (!(sender instanceof Player)){
            sender.sendMessage(ChatColor.RED+"That's for players, silly!");
        }
 
 
 
 
        if (label.equalsIgnoreCase("bow")){
            player.getInventory().setItem(0, new ItemStack(Material.BOW));
            player.getInventory().addItem(new ItemStack(Material.ARROW, 32));
            player.updateInventory();
            player.sendMessage(ChatColor.GREEN+"You got a bow!");
        }
 
        if ((label.equalsIgnoreCase("snowballs"))){
            player.getInventory().addItem(new ItemStack(Material.SNOW_BALL, 32));
            player.updateInventory();
            player.sendMessage(ChatColor.GREEN+"Here are some snowballs!");
        }
 
        if (label.equalsIgnoreCase("egg")){
            player.getInventory().addItem(new ItemStack(Material.EGG, 25));
            player.updateInventory();
            player.sendMessage(ChatColor.GREEN+"Have some eggs!");
        }
 
        return true;
    }
 
}
 

I checked line 29, and its:

Code:java

Player player = (Player) sender;

This used to work before without an exception; has bukkit changed since 1.7.2 bukkit? And how do I fix these problems (console wont receive chat message+the exception)?
**I just noticed CommandSender is an interface, but Idk if that's how its always been.

 

GlacialCreeper You are casting the sender to a Player before you check if they actually are. You need to cast it after you check.

 

Try using:

Code:java

if(sender instanceof Player){
  //dowhatever
}else{
  //dowhatever
}
