Minecraft Bossbar Command Generator
A boss bar is a persistent world object with an id, so the create, set, get and remove commands all have to agree on that id. Build each one here, including the text-component name, and keep the identifier consistent across your command pack.
- create, set, get, list and remove subcommands
- Colour, style, value, max and visibility
- Text-component name with full formatting
FAQ
Why does my bossbar not update?
Every /bossbar subcommand must use the same id. Create with /bossbar add <id> ..., then set value, players and colour with /bossbar set <id> .... A mismatched id silently targets a bar that does not exist.
How do I make a bossbar track a scoreboard value?
Set the bar max to your target, then update /bossbar set <id> value <n> from a scoreboard with /execute store result. The editor builds the set command; drive its value from your objective in a repeating function.
How do I remove a bossbar?
/bossbar remove <id> deletes it. Use the same id you created it with; /bossbar list shows every registered bar if you have lost track.
