Bossbar or Sidebar?
Bossbar vs sidebar
Use a bossbar when you only need a short status line.
Good for:
event name
time left
small score display
rotating short messages
Use a sidebar when you need multiple lines.
Good for:
score
rank
time left
participants
objective hints
extra instructions
Common mistakes
Bossbar text is too long
Keep bossbar text short.
Bad:
text: "&bMining Rush is currently active and you need to mine blocks to gain points before the timer runs out!"
Better:
text: "&bMining Rush &8| &f{time_left} &8| &e{score} pts"
Too many animated bossbar frames
Use 2-4 frames for most events.
Too many frames can make the bossbar feel distracting.
Sidebar has too many lines
Keep sidebars readable.
A sidebar should show useful information quickly, not become a full help menu.
