Skybound

Side-scrolling platformer: one-way ledges, stomps, hazards and checkpoints.

Built on the platformer capability: swept XY box movement against static solids, with jump buffering, coyote grace and short hops already tuned. Seeds, stomps, hazards and checkpoints make it a complete progression loop.

Play it

Play Skybound in your browser. Nothing to install.

Make it yours

The sample ships inside @bendyline/molen-tooling as a template, locked to the engine version you install. Copy it into a standalone npm project (no clone of the engine repository needed):

npx @bendyline/molen-tooling new my-skybound --template skybound
cd my-skybound
npm install
npm run dev

The copy keeps the sample's scene, scripts, commands, checks and headless tests, plus its replay fixture; npm test runs them.

What it teaches

• Platformer physics
• Jump feel (coyote/buffer)
• Checkpoints
• Hazards

The scene at a glance

Read straight out of the sample's scene.json:

Format	molen/scene@3
Tick rate	30 Hz
Entities	97
Prefabs	4
Scene scripts	adventure
Commands	move, jump, restart
Declares	camera, input, physics

Run it headlessly

Every sample is also a headless fixture, so no browser is needed. From your copy:

npx molen validate scene.json
npx molen sim run scene.json --ticks 60 --hash
npx molen shot scene.json --ticks 60 --out skybound.png
