Small graphical turn-based games now drive its library work: +`sys.gfx` provides the optional MiniFB pixel window/input boundary, while +`sys.draw.Canvas` draws rectangles, circles, thick lines, colors, and bitmap +labels entirely in Simple. `docs/examples/TicTacToeGraphical.smp` is the first +game; the existing terminal version remains available. See Chapter 31's +`docs/drawing.md` and `docs/graphics.md`. Sound remains deferred. +Chapter 31 supports `0x`/`0X` hexadecimal and C-style leading-zero octal +integer literals. Cliff explicitly prefers `025755`, not a `0o` prefix. +The 3x5 font uses five octal row digits; packed pixel colors use hex. +Default builds/tests must not download MiniFB or require a display; interactive +launch targets are explicit. Drawing and game checks run without a backend. +Chapter 30 retains the preceding compiler and library. Keep inherited Java test names, use LF for new text files, and do not add Python code or test drivers. Runnable examples belong in `chapter31/docs/examples`. |
