====== Fullscreen mode (ui: fullscreen) ======

The ''fullscreen'' mode turns a room into an **immersive point & click scene**: the [[en:yaml:imagemaps|image map]] fills the whole game screen, without the classic choice panel. Texts appear in a narrative band at the bottom of the screen.

<code yaml>
title: "The tavern"
ui: fullscreen

rooms:
  - id: tavern
    text: "[[#map:scene:tavern.png|tavern-mask.png]]"
    zones:
      scene:
        colors:
          - color: "#FF0000"
            click: talk_barman
            hover-tooltip: "The barman is watching you."
            highlight: true
</code>

===== The narrative band =====

Texts produced by clicks are redirected to the **bottom HUD**. Successive texts from the same click are grouped there to stay readable.

  * While a narrative text is displayed, it **replaces** the content of any ''bottom'' HUD panel declared by the author. To keep information visible at all times, use another HUD position (top, corners...).
  * The band height is set with ''height:'' on the ''bottom'' panel.

<code yaml>
hud:
  - position: bottom
    height: 14
    text: "Welcome to the tavern."
</code>

===== A scene that stays visible =====

The scene **shrinks automatically** to fit between the top and bottom HUDs: nothing is ever covered, and clickable zones follow the image.

After every interaction that changes a variable, the image map is **recomputed live**: a zone that becomes visible (''visible-if:'') or active is immediately usable, without reloading.

===== Single-use zones =====

Combine ''once: zone'' or ''once: zone-room'' on events with ''after-click:'' on zones to visually mark what has already been found - details on the [[en:yaml:imagemaps|Image maps]] page.

===== Leaving the mode =====

A room can switch back to the classic interface locally, and clean the immersive HUDs on the way out:

<code yaml>
rooms:
  - id: tavern_exit
    ui: default
    clear-hud:
      - all
    text: "You step back into the cold night."
</code>

===== Tips =====

  * Without a usable image map, the room shows a plain image or its text: always plan a clickable **exit zone** or a classic fallback choice.
  * On touch screens, the top bar (Give up / Home) stays visible even when the input bar is hidden.
  * The ''test-ui-fullscreen'' demo scenario shows a complete tavern: tooltips, conditional zones, a counter, an exit.
