Minecraft Firework Command Generator FAQ
What changes firework flight duration?
Flight duration is derived from the gunpowder amount in crafting and controls how long the rocket travels before exploding.
Can trail and twinkle be enabled together?
Yes. This generator preserves both independent flags, unlike implementations that accidentally output only one effect.
Why are there modern and legacy commands?
Java 1.20.5 moved item metadata to data components. Older releases use item NBT, so the syntax is substantially different.
