| """Make a capture copy of matrix-shooter-js for paired graybox / styled data. |
| |
| usage: matrix_capture_game.py PACKAGE_DIR OUT_DIR |
| |
| PACKAGE_DIR is the unpacked delivery (start.py, games/, .local/). OUT_DIR gets |
| the same tree with game.mjs patched; the package itself is never modified. |
| |
| The patched game, when the page sets window.__CAPTURE before loading: |
| * does not run its own requestAnimationFrame loop; window.__cap.step() |
| advances it by exactly 1/24 s, so pages fed the same inputs stay in lockstep |
| (the simulation has no randomness of its own; respawns use a seeded PRNG); |
| * takes the camera from window.__camOverride when set, so every style is |
| rendered from the graybox page's camera (styles normally pull the camera |
| further back and widen the field of view); |
| * fires bullets from a style-independent point beside the actor, since each |
| style's gun model puts its muzzle elsewhere and hits would otherwise diverge; |
| * runs team battles: allies (player look) and enemies, each bot hunting the |
| nearest living foe, bullets hurting the other team only, the dead respawning |
| around the player, and the player refilled instead of dying. |
