Player player = (Player) sender?

What does this mean?
I've looked everywhere and Nothing:/

Player player = (Player) sender

????

 

Bernabeast Read a tutorial and stop making multiple threads.

 

Bernabeast So, you've created the method onCommand with four parameters(CommandSender sender, Command cmd, String label, String[] args). CommandSender is self-explanatory and defines the object that ran the command. With

Code:

Player player = (Player) sender;

This casts sender to a Player object, basically stating that an in-game player has ran the command.

 

An example of an instance this may be used?

 

Bernabeast Read my post and stop being ignorant.

 

When we talk about Java Objects, we are actually talking about something that stems from the Object class... for example, A player is extending the following classes:

Code:java

public interface Player extends HumanEntity, Conversable, CommandSender, OfflinePlayer, PluginMessageRecipient

When we're talking about commands, we know that a CommandSender is the person calling the command, if we somehow KNOW that this very CommandSender is also a Player, we can cast CommandSender to Player by using this: ((Player)sender), this would then give us access to all of the methods inside the Player class.
If however, the CommandSender is not a player... IE: A console, you'll get an error thrown as you cannot access a method that this CommandSender does not have.

 

thus, you check if the sender is an instance of the Player class

Code:

if(sender instanceof Player) {
  Player player = (Player) sender;
  // stuff here that requires the player object
}
