Two separate reasons the scripted route stopped, both measured rather than guessed: * LOAD -> READY ROOM is not 28 s. Both runs on 2026-08-23 overran it, so the next press was eaten by the transition and the run ended up in OPTIONS once and BRIEFINGS once. wait_screen.sh now waits for the screen, with an optional --tap that clears a dialog the caller cannot know about (a freshly restored profile inserts "Auto-Save is active. OK?" here). * The READY ROOM is DRAWN long before it is USABLE: it comes up with a "Preparing to Sortie" spinner and TAKE OFF greyed out. The two states differ by 1.7 units of blue whole-image, so screen_id.py cannot separate them and should not try. take_off_armed.py tests the label instead: 0.0000 bright pixels while preparing, 0.1633 once armed, on three captures from two runs. It carries its own position check - the always-enabled BRIEFINGS label below reads 0.1027 in all three, to four decimals, so if that reference is dark the boxes are off the labels and the answer is "unknown", not a confident wrong one. screen_id.py gains a "readyroom" class from the same measurements; nothing else reclassifies. Verified end to end and unattended: boot -> title -> LOAD GAME -> slot 01 -> READY ROOM -> TAKE OFF -> "IN FLIGHT at 34s", pilot bound and engaging.

"""Identify which game screen a screenshot shows, without fixed pixel positions.
|
|
|
|
The nav scripts used to test named pixels ("648,221 is white"). That works only
|
|
while the game image sits at a known place on the root window, and it does not:
|
|
xenia's GTK window has a menu bar, so on some displays the image is ~25 px lower
|
|
and every constant reads the wrong row. The failure is silent and expensive — a
|
|
run sat on a plainly visible MAIN MENU for 300 s reporting "no main menu", and a
|
|
later one missed the title screen so the attract movie looped for ten minutes.
|
|
|
|
So identify screens by WHOLE-IMAGE statistics instead, which no vertical shift
|
|
(or scale, or letterbox) can move:
|
|
|
|
green fraction of pixels that are the game's green UI text/HUD colour
|
|
white fraction of near-white pixels
|
|
mean per-channel mean
|
|
|
|
Measured on known-good captures of each screen (1280x720, no menu bar):
|
|
|
|
title green 0.11% white 7.4% mean (62, 75, 84) blue-ish, bright
|
|
main menu green 0.04% white 3.5% mean (25, 38, 70) dark, strongly blue
|
|
in flight green 1.2% white 3.4% mean (54, 39, 37) green HUD everywhere
|
|
movie green 0% white varies no green at all
|
|
|
|
Usage: screen_id.py <png> [--json]
|
|
Prints one of: title | menu | readyroom | flight | other, plus the features.
