Abyss Town

A small living town you can walk around in your browser. Talk to the residents, invite the dog to follow you, and watch the wind move through the trees.

Nothing to install and no account. It runs on your own device; the first visit downloads about 14 MB (55 MB of town data, compressed), and the browser keeps it for next time. 中文介面可在選單切換。

The whole town from above: houses around a market square, a stream with bridges, a pond, farm fields, orchards and a forest. — The whole town: market square, stream and bridges, pond, farms, orchards and the forest. 405 objects, drawn live in WebGL 2.

What you can do

Walk in, say hello

Walk, run and jump. Click or tap the ground, or take over with the keyboard. Fall over and get back up.
Talk to the residents. Select someone and choose Talk; conversations appear as speech bubbles over their heads.
Bring the dog along. Ask it to follow you or to wait. It keeps pace when you run.
Wind and water. Trees, crops and grass sway; the water painted into the ground ripples. Both can be switched off.
Three camera distances and three picture-quality settings, from light to full quality.
English and Traditional Chinese, switchable at any time without losing your place.

The player talks with a resident by the well; a speech bubble reads “Sure! Let’s chat.” — Choose Talk and the resident answers in a speech bubble.

Residents near the well with a dog and a sheep; the Dog panel offers Follow me and Approach. — Select the dog and ask it to follow you.

How it’s made

One engine, everything drawn by its own tools

Abyss Town is the meeting point of everything Abyss Engine has been building: the same C code runs it here in WebAssembly and in the native Mac and iPad builds.

Abyss Engine

A portable C11 engine. Movement, conversations, the dog’s following and the residents’ routines are shared game code, not a separate web version.

Abyss UI Maker

Every panel, button and speech bubble is drawn by UI Maker from design recipes, in English and Chinese. The page itself holds only canvases; there are no HTML widgets.

AbyssScript and Behavior IR

What the menus do, and much of what the residents and animals do, is written as small scripts compiled to a compact behaviour program the engine runs.

Models from programs

Houses, props, crops and trees are described by small mesh programs and a building kit in the Abyss mesh editor, then packed into compact binary models: 100 models for 405 objects.

Physics and picture

Jolt Physics for walking, falling and getting up. A WebGL 2 renderer with HDR lighting, soft shadows, ambient occlusion, bloom, authored materials, GPU wind and procedural water.

This is a preview. Going indoors, helping someone up and sound are not in the web version yet. It is tested in Chromium and WebKit (Safari’s engine), on desktop and phone-sized screens; a full pass on real phones is still to come.
