Has it changed?

Code:

public void setFire(Player player){

    String[] s;
    Event event = event.getPlayer();

    if(event.getPlayer().isOp() && s[0].equalsIgnoreCase("/fire")){
        //Define a variable of type Player for storing the person to set on fire (initially set to null).
        Player target = null;
        //Check whether there command includes an extra argument for player name
        if(s.length > 1)
            //If so, set target to be the player with the name given
            target = event.getPlayer().getServer().getPlayer(s[1]);
        //if by this point target is still equal to null, either a name argument wasn't supplied or there was no player with that name.
        if(target == null)
            //in that case, target the player calling the command.
            target = event.getPlayer();
        //set target on fire.
        target.setFireTicks(100);

    }

    }

My events aren't working, and they used to, what has changed that i need to fix? Can anyone tell my what's wrong? (With the events)

And side note, did i set up my strings right?
I'm trying to get it so when you type in: '/fire <player name>' it lights that player on fire.

 

First:

Code:

Event event = event.getPlayer();

again, where is event defined?

Second:

Code:

String[] s;

should be

Code:

String[] s = something.split(" ");

 

Yeah, i got yelled at for that by plague XD Thanks though.
