How to Test the Custom Boss Bars and Icons in a Creative World

Before jumping into a survival boss fight, you can quickly verify that the Minecraft Dungeons-inspired boss health bars and matching font icons are displaying properly by testing them in a Creative mode world.

Spawning a Vanilla Boss

1. Create or open a Creative mode world with commands enabled.

2. Travel to an open area away from important builds, activate the End portal to visit the End dimension, or build a Wither structure using Soul Sand and Wither Skeleton Skulls.

3. Look at the top center of your screen as the boss spawns. The standard segmented or plain vanilla health bar should now be replaced by the custom design styled after Minecraft Dungeons, complete with its matching boss bar font icon.

Testing Without Spawning Mobs

If you want to preview the bar appearance without dealing with destructive mobs in your test world, you can use vanilla Minecraft's built-in /bossbar command.

1. Open the chat window and run /bossbar add test "Boss Test" to register a temporary bar.

2. Run /bossbar set minecraft:test players @s to make the bar visible on your screen.

3. Change the bar's color or style using /bossbar set minecraft:test color <color> or /bossbar set minecraft:test style <style> to inspect how the pack handles different vanilla boss bar states and icons.
