Firework Launcher

Turns the vanilla firework rocket into a hand-held launcher, adds 160 TNT firework rockets, two new hostile mobs and an elytra-like glider - all for Minecraft 26.x on Fabric.

Hand-held rocket launcher

• Aim at open air, hold right-click (default 0.5 s, adjustable in Options), release to fire.
• The rocket flies perfectly straight in any direction and deals 6 points (3 hearts) on a direct hit.
• Aim at a block to keep the vanilla behaviour (place it and let it fly up).
• Hold it longer than 2.5 s and it detonates in your hand.
• Options -> Firework Rocket... adds a Charge Time slider (0.1 s - 2.0 s).

160 TNT firework rockets

• 16 TNT counts x 10 flight durations = 160 items: tnt_firework_rocket_<tnt>_<flight>.
• Craft N TNT + 1 firework rocket (shapeless, top-up supported: 8-tier + 8 TNT = 16-tier).
• Detonates like the same amount of TNT - real blast, real block destruction, TNT_EXPLODES honoured.
• Crossbows fire them. Elytra boosting works too, but the boost ends in a TNT blast.
• Flight durations up to 10: craft a rocket, then add gunpowder to extend its flight (rocket + N gunpowder).

Creeper Phantom & Charged Creeper Phantom

• Insomnia spawner in the Overworld: don't sleep for 3 game days (60 min) and they hunt you at night.
• 21x21 area, 20-34 blocks above you; 1-2 / 1-3 / 1-4 depending on difficulty.
• A creeper head with phantom wings (vanilla textures, no new art). Explodes like a creeper within 1 block of you, or instantly when hit by any projectile - including every firework rocket.
• During thunderstorms, 50% spawn charged (double the blast, creeper energy overlay). Spawn eggs included.

Assist Elytra (original white + wooden-trim art)

• 2 sticks + 2 phantom membranes (shaped: membranes on the sides, sticks in the middle).
• Glides like an elytra with 72 durability; shatters when used up (10% chance to drop a membrane).
• White with a wooden trim when worn - visually distinct from the vanilla elytra.

Notes

• Config: config/firework-launcher.properties.
• Same jar works on client and server.
