Both examples declared their gameplay variables at the top level even though every read and write happened inside one specific state. That pattern hid the overlay feature from new users and kept the state-local code path from being exercised outside the dedicated `state_machine.ne` demo (which is how the "state-locals silently drop their writes" bug survived so long). `coin_cavern.ne`: the five Playing-only physics/position/inventory vars (`player_x`, `player_y`, `player_vy`, `on_ground`, `coins_left`) move onto Playing's state block. `score` stays global because GameOver-era code could reasonably grow to read it. The `on_enter` body loses its redundant resets — the declared initializers on the state-locals re-run on every entry, so retrying after `transition Title` comes back to a fresh state. `platformer.ne`: player physics, camera, liveness, animation phase, and the autopilot budget (`player_y`, `on_ground`, `rise_count`, `fall_vy`, `camera_x`, `anim_tick`, `alive`, `auto_jumps`) all move onto Playing. `frame_tick` and `stomp_count` stay global — Title reads the former to auto-advance, GameOver reads the latter to tally coins on the death screen. The analyzer now overlays Title's `blink`, Playing's eight physics vars, and GameOver's `linger` starting at the same ZP byte (`$1A`), so the three scenes share a 9-byte window instead of each claiming their own slots. Byte-level ROM bytes for both examples shift because variable addresses moved. Video goldens stay pixel-identical (the harness doesn't see Playing in coin_cavern, and the pre-transition Title→Playing timing in platformer is preserved); the platformer audio hash needed one more refresh because the now-slightly-shorter reset prologue shifts APU writes within each frame. https://claude.ai/code/session_015kvJu3iEFLSRJoShPBfm3X |
