# Basic Usage

Creates an `XWUIGameBossHPBar` in `#app` with empty data and config, so it uses the defaults: `hp` and `maxHp` 100 (a full `100 / 100` bar), `phases` 3, and `showName`/`showPhases` on with no `name` set. Pass `name`, `hp`, `maxHp`, `phases`, and `currentPhase` (or a string as `data` to set just the `name`), and call `setHP()` or `updateData()` to animate the fill.
