Side-scrolling platformer

Goal

Adapt templates/side-scroller: double jumps, platforms, patrols and checkpoints.

Files you will edit

• src/game.ts — controls, camera and round rules.
• src/level.json — actor placement.

Steps

1. Keep characterMovement({ planeZ: 0 }), char.hero and the template's jump budget.
2. Tune sideScrollCamera bounds; reset it on respawn.
3. Place axis-aligned SoftPlatform actors. Their half extents are [2, 0.15, 1] before actor scale. Descending characterMovement capsules land on top.
4. Down+jump calls dropThroughPlatform(hero.entity); allow room below.
5. Give platforms and pads mesh assets. Mesh props.scale affects only the look.

Verify

Run npm test. Test keyboard, gamepad and touch: double jump, rise through a soft floor, land and drop; check lives, respawns, stomps and the goal route.
