HUD - Persistent Panels (YAML)

HUD panels (hud:) display persistent information on the player screen: HP, score, mini-map, countdown, and so on.

HUD panels are visible on web and desktop. On Discord and terminal they are ignored; essential information should also appear in narrative text.

• top-left, top-right, bottom-left, bottom-right

The video syntax can be used inside the text of a panel:

hud:
  position: top
  text:
    - "((loop;muted:https://example.com/video.mp4))"

A hosted video works here too. See Sounds, images and videos.
