Show a bar in three lines
/bossbar add timer "Time left"
/bossbar set timer players @a
/bossbar set timer color yellowThe first line creates the bar, the second shows it to everyone. A new bar is not visible to anyone until you set players. timer is the bar's ID; use lowercase letters, numbers and _.
Appearance settings
| Setting | Example | Values |
|---|---|---|
| Color | /bossbar set timer color red | blue, green, pink, purple, red, white, yellow |
| Style | /bossbar set timer style notched_10 | progress, notched_6, notched_10, notched_12, notched_20 |
| Text | /bossbar set timer name "Boss fight" | A string or a text component |
| Visible | /bossbar set timer visible false | true, false |
For colored text use /bossbar set timer name {"text":"Boss fight","color":"red","bold":true}. This form works both before and after the 1.21.5 text format change.
Fill level: max and value
/bossbar set timer max 60
/bossbar set timer value 45The bar is filled to value ÷ max, so this example is three quarters full. The default max is 100.
A countdown linked to a scoreboard
Count the time in a score and copy it into the bar every tick. This example is a 30-second (600-tick) timer.
Setup (run once):
/scoreboard objectives add time dummy
/scoreboard players set #timer time 600
/bossbar add timer "Time left"
/bossbar set timer max 600
/bossbar set timer players @aIn a repeating command block and a chain command block (always active):
scoreboard players remove #timer time 1
execute store result bossbar timer value run scoreboard players get #timer timeTo stop at zero, change the first line to execute if score #timer time matches 1.. run scoreboard players remove #timer time 1.
Players who join later
players @a only adds the players online at that moment. To include players who join later, run bossbar set timer players @a every tick from a repeating command block.
List, check and remove
/bossbar listlists all bars./bossbar get timer valueshows the current value (alsomax,players,visible)./bossbar remove timerdeletes the bar. Bars are saved with the world, so remove ones you no longer need.
Common problems
- Nothing appears: run
/bossbar set timer players @a. - The bar stays empty: check the value with
/bossbar get timer value. - Unknown command: Bedrock Edition has no /bossbar. Use
/titlerawwith actionbar to show a timer as text instead. - Invalid ID: IDs cannot contain capital letters or spaces.
