Use this page when setting up the Build System in a project for the first time. The minimum working flow is: Build Placement Settings → Buildable Inventory Item → Build Part prefab → Builder with Bag + Build Tool → Start/Confirm placement instructions.

Requirements

The module assembly directly depends on:

• Game Creator 2 Core
• Game Creator 2 Inventory
• Unity Input System

The optional runtime NavMesh workflow can integrate with Unity AI Navigation when NavMeshSurface/NavMeshLink are present. The core placement workflow does not require you to enable NavMesh support on a Build Part.

1. Create the shared placement settings

In the Project window use Create → Game Creator → Build System → Build Placement Settings.

A BuildPlacementSettings asset provides the defaults used by the builder. Important groups include:

• Aim — Pointer, Camera Center, or Forward From Builder.
• Raycast — surfaces that can receive free placement and maximum placement distance.
• Snapping — global socket search, socket-target layers, and search distance.
• Grid — global grid size/origin.
• Rotation — default rotation step.
• Validation — blocking layers and trigger policy.
• Preview — valid, invalid, and dismantle-preview materials.
• Continuous Placement — repeated placement behavior.
• Dismantle — layers and distance used when selecting a placed part to destroy.
• Placed Hierarchy — optional grouping of spawned build parts.
