player.hasPermission problems

Hi,
i am making a custom plugin but need to check if the player has a permission.
Here is my code:

Code:java

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
Player player = (Player) sender;
if(cmd.getName().equalsIgnoreCase("fly")) {
if (player.hasPermission("billcraft.vip")) {
if (player.getAllowFlight()) {
player.setAllowFlight(false);
player.sendMessage("§eFlying has been disabled.");
} else {
player.setAllowFlight(true);
player.sendMessage("§eFlying has been enabled.");
}
} else {
player.sendMessage("§cYou cant do this!");
}
return true;
}
return false;
}

Any 1 know what my problem is?

 

What exactly is your problem?
Try and check your plugin.yml
and before you cast player check if the sender is a player cuz if the console sent this command you would get a pain of errors

I think it might be how i setup PermissionsEx,
The default rank dosnt have billcraft.vip and can still use /fly.
Also Any 1 know how to setup ladders (eg. /promote user ladder)

 

Add the permission to your plugin.yml and set default to op.
