Jump pad

A same-floor travel recipe moves the entering player four cells east when a safe landing exists.

What it demonstrates: Offset travel · host-authoritative movement.

Run this example

This example requires a host with generic travel support. Check host compatibility before trying it.

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-jump-pad --template jump-pad

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

Try a different bounded offset and exit order. Validate blocked, occupied, and out-of-bounds landings on a compatible host.
