Chunk format/Arrow


 * : 0 = cannot be picked up by players. 1 = can be picked up by players in survival or creative. 2 = can only be picked up by players in creative.
 * : 1 or 0 (true/false) - If pickup is not used, and this is true, the arrow can be picked up by players.
 * : Increments each tick when an arrow is not moving; resets to 0 if it moves. When it ticks to 1200, the arrow despawns.
 * : Damage dealt by the arrow, in half-hearts. May not be a whole number. 2.0 for normal arrows, and increased 0.5 per level of Power enchantment on the firing bow. If the Power enchantment is present, an additional 0.5 is added on (so Power I gives a bonus of 1.0, while Power II gives 1.5).
 * : 1 or 0 (true/false) - If the Projectile is in the ground or hit the ground already (For arrow pickup; you cannot pickup arrows in the air)
 * : 1 or 0 (true/false) - Whether the arrow will deal critical damage.
