Power Ups

Feature available from 1.8.5+

Also check this example plugin to learn how to create power ups.

A power up is very simple, is made of a floating item (the icon) and a hologram. You can assign a PickupHandler to the floating item, that is triggered when a player is near. If you want, you can create a class that holds both the hologram and the floating item.

Example: a power up (Blaze Powder) that gives fire resistance when is collected.

String text = ChatColor.GOLD  + "" + ChatColor.BOLD + "Fire Resistance"
Location where = ... // Suppose you have a random location in your minigame

ItemStack powder = new ItemStack(Material.BLAZE_POWDER);
FloatingItem floatingItem = HolographicDisplaysAPI.createFloatingItem(this, where.add(0.0, 0.2, 0.0), powder);
final Hologram hologram = HolographicDisplaysAPI.createHologram(this, where.add(0.0, 0.6, 0.0), text);

floatingItem.setPickupHandler(new PickupHandler() {	

	@Override
	public void onPickup(FloatingItem floatingItem, Player player) {
					
		// Play a sound
		player.playSound(player.getLocation(), Sound.LEVEL_UP, 1F, 2F);
					
		// Play an effect
		player.playEffect(floatingItem.getLocation(), Effect.MOBSPAWNER_FLAMES, null);
					
		// 1 minute of fire resistance
		player.addPotionEffect(new PotionEffect(PotionEffectType.FIRE_RESISTANCE, 60 * 20, 1));
					
		// Delete the hologram and the floating item
		floatingItem.delete();
		hologram.delete();
					
	}
});
