Gate

Introduction

A Gate is a structure in space that enables travel between locations. Two gates link together to create a transport route. Gates are programmable — the owner can deploy custom extension contracts to control who can jump.

Default Behavior

By default (no extension configured), anyone can jump through the gate without restrictions.

Custom Behavior (Extension)

When the owner configures an extension, the gate switches to a permit-based model:

1. The owner deploys custom jump rules (a Move contract) and registers it as the gate’s extension.
2. Players must obtain a jump permit from that logic (e.g. by meeting a tribe check, paying a toll, or completing a bounty) before they can travel.
3. The game validates the permit and allows the jump. Permits are tied to a route and an expiry time; a permit for Gate A ↔ Gate B works in both directions.

For a full working example, see builder-scaffold smart_gate.

Linking Gates

Two gates must be linked before anyone can jump between them. Requirements:

• Both gates must be owned by the same character.
• Gates must be at least 20 km apart (verified with a server-signed distance proof).
• Linking requires an authorized transaction (the game validates this).
