TXT — In-Game Text and UI Layout (.TXT)¶

FA_2.LIB contains 8 .TXT files. The extension covers three distinct uses of the same directive engine: campaign selection descriptions, interactive UI screen templates, and plain-text content (credits). All are plain ASCII, CRLF.

Tools¶

fx¶

fx txt info <file.TXT>     # kind + directive structure + round-trip check

The parser is line-preserving — txt_read/txt_write round-trip any input byte-identically while exposing the directive structure — and is written for reuse by the .MT briefing codec (#108), which shares the directive engine.

File Layout¶

Plain text; no binary fields.

Directive Engine¶

The .TXT format uses the same directive engine as .MT briefing files, plus two UI-specific additions:

Directive	Description
`.section <N>`	Begin numbered section
`.header`	Switch to header render style (may be used inline: `.header <text> .body`)
`.body`	Switch to body render style
`.center`	Center-align subsequent text
`.left`	Left-align subsequent text
`.underline`	Enable underline
`..underline`	Disable underline
`.page`	Page break — advance to next screen without starting a new section
`.button <label> ..button`	Interactive button element; label text is between the open/close tags
`.picture`	Image placeholder — engine renders the current context image (e.g. nose art)

Campaign Description (6 files)¶

Two-section structure. Section 2 contains only END — a sentinel the engine uses to detect end-of-file.

.section 1
.header
<Campaign title>
.body
<One-paragraph description>
.section 2
END

Example — BALTIC.TXT:

.section 1
.header
The Baltics 2009
.body
Fly missions over Estonia, Latvia, and Lithuania, defending them from aggression.
.section 2
END

UI Layout Template (SHWPILOT.TXT)¶

Defines the Pilot Service Record screen. Uses .page to separate tabs, .button for navigation controls, and .picture as the image render target for nose/tail art. Button content between .button and ..button is the button label; an empty .button ..button pair defines an editable input field.

.center
.header PILOT SERVICE RECORD .body

.left

NAME: .button  ..button

CALLSIGN: .button  ..button
.page
.center
.header NOSE ART .body

.picture

.button Previous Picture ..button    .button Next Picture ..button

Plain Text (CREDITS.TXT)¶

No directives. Raw ASCII credits block rendered verbatim.
