The console at the window's size

Reported from play: the console worked, but its text was far too large and there was no way to move around the line or the log. The window's title was the long Mode::title line.

Why it was large

The console drew into the GS frame, 512 x 448, which the presenter then stretched to the window. Each 8 x 16 glyph came out two or three times its size, blurred by the scaling. The glyphs were also cut off on the right. The port read ef8x16's trim as the glyph's width. It is really the texels to remove, and a glyph is left-aligned in its cell, so the advance is 8 less the trim.

The console now

  • Drawn at window pixels. piney_gs::Presenter gained an overlay: an RGBA picture laid over the top of the swapchain after the frame's blit, with a nearest sampler. Console::overlay(width, height) builds it:
    • a band of 2/5 of the window's height;
    • a rule under the band;
    • the log, the newest line just above the prompt;
    • the prompt, with a cursor bar. The glyphs come from the game's own ef8x16 small font (Fonts::small_ascii), at 1:1, or 2:1 on windows 1400 pixels high or more. A help line's second column starts at a fixed x, since the font is proportional. Console::draw still draws into the GS frame, but only for --shot.
  • Keys.
    • Editing: Left, Right, Home, End, Backspace, Delete, Ctrl+A, Ctrl+E, Ctrl+U (clear the line), Ctrl+L (clear the log).
    • History: Up, Down.
    • Scrollback: PageUp, PageDown, over a log of 1000 lines.
    • Tab: completes a command, from the names in help.
    • Escape: closes the console. The app follows Ctrl through ModifiersChanged.
  • Window title. Now piney - <volume title>.

God-mode commands

commandwhat it does
godToggles god mode. While on, the session calls heal_party after each area frame.
killAreaMode::kill_enemies: each enemy standing takes EntryAffect(1, 9999) from Kite, so it falls with its own exp and drops.
protectAreaMode::break_protects: each enemy's ppCount becomes 1800 (60 s), so Data Drain takes it.
infection NThe bracelet's infection (save +0x676e), clamped to 0..=100. With no N, it shows the value.

The new test the_console_cheats walks into event 3's fight and checks the four commands:

  • protect and kill report the goblins, and they fall;
  • under god, Kite's HP, set to 1, is full again 30 frames later;
  • infection 150 stores 100.

console_picture (ignored) writes the console over a grey window to the shots folder, to look at it by hand.

Still unknown

The game's log lines (stderr) do not reach the console. Teeing them would need the process's stderr redirected into a pipe the app reads. Nothing is scrolled horizontally, so a line wider than the window is cut off.
