Walkable tile

The smallest collision example: an ordinary tile players can walk through.

What it demonstrates: Walkability without effects.

Run this example

All learning examples appear in a compatible developer world. To export a standalone project, an operator with source access runs this from the Scape repository (choose a new destination under an existing directory):

yarn sdk:starter /path/to/my-walkable-tile --template walkable-tile

In the exported project:

yarn install
yarn build
yarn dev --origin https://your-scape-host

Follow connection and approval. The exported dev script invokes scape gizmo dev. The kit includes three private archives for the SDK, CLI and MCP server; keep them and the Yarn resolutions together. Third-party dependencies still need installation. See the CLI reference for commands; no public Scape registry install is available yet.

Try changing it

Add a cosmetic step callback without adding state or an editor. Walkability and feedback are independent.

Source

This code is included directly from the working example when the site builds.

src/definition.ts

/** This tile declares walkability; Scape supplies collision, movement and placement. */
import { defineObject, exactKeys, record } from '@scape/sdk';

/** Walkability is independent: this tile has no actions, arrival effects or push. */
export const walkableTile = defineObject<Record<string, never>>({
  type: 'example.walkable-tile',
  version: 1,
  emoji: '🟦',
  label: 'Walkable tile',
  hint: 'a floor tile with no movement or arrival effects',
  initial: () => ({}),
  valid: (state): state is Record<string, never> => record(state) && exactKeys(state, []),
  actions: {},
  walkable: true,
});
