Examples ​

Small, real games built with debuff, each with its source, controls and the docs behind it. They run against the current release (0.1).

Plinko: sprite stress test ​

Balls fall through a peg board and a spinning paddle into bins. It's calm by default. Press stress test and it keeps adding sprites while your device holds 60 fps, then shows how many it held.

  • Controls: click or tap the board to drop more balls; play/pause in the corner.
  • Shows: batched draw.sprite at scale, a fixed-step simulation, allocation-free hot loops, game.stats.
  • Source: examples/plinko/plinko.ts, about 300 lines using only @debuffjp/core.
  • Docs: Drawing · Core concepts · Benchmarks

Platformer ​

buff runs, jumps and collects coins across a level made in Tiled. This is the platformer template, unchanged. It's a production build, so it opens with the "made with debuff" card.

  • Controls: arrow keys or A/D to move, Space, Up or W to jump, Down to drop through orange platforms. A gamepad works too.
  • Shows: Tiled level import, tile collision with one-way platforms, coyote time and jump buffering, a camera with deadzone, an atlas-packed sprite sheet, particles and squash-and-stretch.
  • Source: templates/platformer. Start your own copy with:
bash
npm create debuff@latest my-game -- --template platformer

Mossfell ​

A wanderer crosses the fell, screen by screen, to find the mossheart in the hollow below. Swing a blade at slimes, moths and thornbulbs, find the key, open the door and face the warden. Moss and plum instead of lime: debuff doesn't come with a look of its own.

  • Controls: arrow keys or WASD to move, Z, Space or J to swing. A gamepad works too.
  • Shows: screen-by-screen scrolling over one Tiled map, a small dungeon behind stairs, sword hitboxes and knockback, hearts and invulnerability frames, enemies that respawn per screen, and synthesized sound effects.
  • Source: templates/mossfell. Start your own copy with:
bash
npm create debuff@latest my-game -- --template github:debuffjp/debuff/templates/mossfell
