Also, here's the line of code that's causing the problems (The following is both line 747 & 762):

Code:java

Player player = (Player) event.getEntity();

Please reply ASAP.

 

Check is the entity is instance of a Player object?

 

You cannot cast it as a player, it has to be an entity, then you can check if it is a player like so:

Code:

Entity ent = event.getEntity();
 
if (ent instanceof Player) {
    Player player = (Player) ent;
}

 

Also : Have you got a @EventHandler on top/have you registered the event? and does
Caused by: java.lang.ClassCastException: org.bukkit.craftbukkit.v1_6_R2.entity.CraftPig Ring a bell?

Yes, my event has the EventHandler and I have registered my event.

My code includes a 'player.getLevel()'. How will I be using this if I use Entity instead of Player?

 

Code:

if (event.getEntity().getType() == EntityType.PLAYER) {
  Player player = (Player) event.getEntity();
  // next code
}

Thanks! I changed your code a little bit and it works perfectly!

 

Better check :

Code:java

if(e.getEntity() instanceof Player)

Just saying
