Check if a player has permission to a command

I am trying to figure out how to make it when a person executes a command to have it check to see if they have access to it. If not I want to manually cancel it and send a message. Here is what I currently have.

The error is on the line with the if statement. I am getting a null pointer exception.

Code:

    @EventHandler(priority = EventPriority.HIGHEST)
    public void cmdListener(PlayerCommandPreprocessEvent e)
    {
        if(!plugin.getServer().getPluginCommand(e.getMessage()).testPermission(e.getPlayer()))
        {
            e.getPlayer().sendMessage(plugin.string.translate(plugin.resource.getString("messages.yml","cmd-cancelled")));
            e.setCancelled(true);
        }
    }

 

Player.hasPermission("command.perm") returns true or false.

 

Code:java

if (player.hasPermission("your.permission.name"){
      // Do Something
} else{
      player.sendMessage("no permission");
}

Hope I helped !

 

bubba1234119 The problem is that you have to get get string.substring(1);, as commands don't have the "/".

 

Hold on looking into this.
