Grid Builder

Use grid-snapped placement foundations for building and decorating games.

What you can build

• Grid-snapped placement with rotation and footprints (tycoons, base builders, decorators)
• Ghost preview that shows valid/invalid before placing, on desktop AND touch
• Server-authoritative placement checks with occupancy and cost hooks to validate in your game.
• Cost hooks that plug straight into the Economy Kit
• Occupancy tracking to check placement footprints.

Before you start

Scope and limitations
