BossBar Hud
Overview
There are two display modes for the BossBar Hud: Line Mode and Layout Mode.
Line Mode
In line mode, multiple elements are arranged in the same line. The position of each element dynamically changes based on its order in the line.
Layout Mode
Version Limitation
Since the shader core for resource packs is supported only in versions 1.17 and above, the 1.16.X versions can only use line mode display and do not support layout display.
Layout mode, on the other hand, references the layout configuration and is used to display HUD elements fixed on the screen.
Unlike line mode, the elements in layout mode have fixed positions, and you can freely adjust their placement without being influenced by other elements.
