Development Assistance Horse Mount

I made a horse mount and whenever I click the apple to spawn it, it doesn't do anything.

Code:

public class mount extends JavaPlugin implements Listener {
    public void onEnable() {
        this.getServer().getPluginManager().registerEvents(this, this);
    }
    @EventHandler
    public void onPlayerUse(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        if (player.isInsideVehicle())
        if (player.getItemInHand().getType().equals(Material.APPLE)) {
            Horse h = (Horse) player.getWorld().spawnEntity(player.getLocation(), EntityType.HORSE);
            h.setTamed(true);
            h.setAdult();
            h.setVariant(Horse.Variant.SKELETON_HORSE);
            h.getInventory().setSaddle(new ItemStack(Material.SADDLE, 1));
            h.setPassenger(player);
        }
    }
}

 

I don't think you put the apple spawning the horse. That's what I think.

 

fixed it, had to return after if (player.isInsideVehicle()).
