The specific instructions are: An image of the ender dragon and wither bossbars.
A bossbar is a bar that can track a boss mob's health or the total health of raid mobs.
Manual creation[]
A bossbar can be shown using the /bossbar command. β[Java Edition only]
Natural creation[]
Boss mobs[]
A bossbar appears in the top center of the screen when near a wither or ender dragon.
For the ender dragon's bossbar to appear, the player must be within a Euclidean distance of 192 blocks from the coordinates (0.0, 192, 0.0) in the End dimension.[needs testing]
For the wither's bossbar to appear, the player must be loading the chunk the wither is in and be within 24 chunks and 3.5 blocks of a chunk the wither is in.
Raids[]
When a player is within a 93 radius of the center of a raid, a raid bossbar appears, showing the total health of all raid mobs present during the current wave.
Parts[]
Color[]
The bossbar has colors depending on which boss mob or event is active.
The ender dragon has a color of pink. The wither has a dark purpleβ[Java Edition only] or pinkβ[Bedrock Edition only] bossbar. The raid bossbar has a color of red.
ID system[]
A bossbar has an ID, which can be used to do certain actions with one bossbar. An ID is not shown on the creation of the bossbar[verify], so you can't see it.
Removing[]
A bossbar can be disabled by using /bossbar remove <id>.[more information needed]
