The firework rocket was added to Minecraft in v1.4.6 as a part of the Christmas Update. Rockets are able to fade, shade, and have special effects. These can all be determined by the materials used in crafting the rocket. Fireworks can be customized into many different colors, sizes, and heights.
Fireworks can be crafted quite easily by the player with the use of paper, gunpowder, and a firework star. Firework stars of different colors, shapes, and effects, can be combined when crafting a Firework Rocket to make a rocket with every aspect of the stars, without blending colors together. Adding more gunpowder to the recipe will increase the height of the flight before the explosion.
Fireworks can be used for recreational purposes, to propel players when using the elytra, or as ammunition for crossbows.
Players can launch a firework by pressing the ‘use’ key on a block, they can also be launched from dispensers and crossbows. If shot from a multishot crossbow, then 3 rockets fire with the same effects.
When a player uses a firework rocket while flying with elytra, it will propel the player in the direction they are facing. The duration of the speed boost depends on the flight duration of the rocket. If the rocket is equipped with a firework star of any kind, the player will take damage when it explodes.
A firework rocket can be used as ammunition for crossbows although it deals damage only if it has an explosion effect. A higher flight duration gives the firework rocket a longer range, and more damage is added per firework star. If a firework rocket shot from a crossbow hits an entity, the rocket instantly explodes, no matter the flight duration.
Firework rockets are craftable items that can be used for a variety of purposes which include recreation, ammunition, and to propel players using elytra. They are quite easy to craft as they only require paper and gunpowder, they have a variant that allows players to add a firework star into the crafting process making the firework explode and creating a colored pattern in the sky.
