Two questions. New to Java/Bukkit API.. confused.

1. How do I set it so when a player types in a command and left/right clicks on a mob they are now this and that, with permissions.

2. How do I get that selected mob to detect something in a certain radius. (Say if a player has a certain item.)

I'm really new to the Bukkit API and I have NO idea what to do whatsoever.

 

I can help with a few things..
If a player has an certain item:
if(player.getInventory().containsAtLeast(item, 1)){

 

Then how do you detect if he is in radius, then causing the mob to attack?

Bump.

I wrote this up for you to give you most of the info i think u need, You should be able to work it out from here.

Code:

    @EventHandler (priority = EventPriority.HIGHEST)
    public void onAttack(EntityDamageByEntityEvent e){
     
        Entity victim = e.getEntity();
        Entity attacker = e.getDamager();
     
        if (victim instanceof Creeper){
         
            if (attacker instanceof Player){
                Player p = (Player) attacker;
             
                if (p.getInventory().containsAtLeast(new ItemStack (Material.DIAMOND_SWORD), 1)){
                 
                    if (p.getItemInHand().equals(Material.DIAMOND_SWORD)){
                        p.sendMessage("You just hit a creeper with a diamond sword");                 
                    }                 
                }
             
                for (int i = 0; i < victim.getNearbyEntities(10, 10, 10).size(); i++){ // loops through all entities within a radius of 10 blocks
                    if (victim.getNearbyEntities(10, 10, 10).get(i) instanceof Player){ // checks if the entity is a player
                        Player p2 = (Player) victim.getNearbyEntities(10, 10, 10).get(i); //gets the player
                        if (p2.getInventory().containsAtLeast(new ItemStack (Material.TNT), 1)){ //checks if player has tnt in inventory
                            p2.getWorld().createExplosion(p2.getLocation(), 4F, true); // blows player up.
                        }
                    }
                }
            }
        }
    }
