NorthKit: Builder System

Build Bases That Behave Like They Have Real Weight

NorthKit: Builder System is a complete, modular base-building system designed to integrate into your existing Unity project. Place buildable pieces, snap them together, craft and gather - and watch badly supported structures actually collapse. Create and configure everything through Data Assets and the Inspector, without writing system code for normal use.

Complete Building System

Everything you need for base-building in one modular system:

• Build Mode
• Buildable Pieces
• Snapping
• Structural Integrity
• Editing & Demolition
• Build Cost & Refunds
• Crafting (Workbench & Handcraft)
• Gathering with Tools
• Aging & Decay
• Save Support

Real Structural Integrity

This is the heart of the package. A structure is not a pile of independent pieces:

• Every piece must trace a path back to the ground.
• Pieces carry the load of whatever rests on them.
• Remove a support or overload a piece and the structure collapses - in a cascade that can bring down its neighbours.
• Pieces age and decay over time.
• Decoration (torches, lamps, flags) falls with the wall it is attached to.

It is always live, and it is what makes a base feel like it has real weight.

Data-Driven & No-Code

A buildable is a prefab with one component, a recipe is an entry in a book, a tool is an item asset. Author and balance everything in the Inspector instead of editing system code.

Create -> Configure -> Use

Modular by Design

Use only what your project needs. Every major component is optional, so you can ship anything from a simple placement system to a full base-building experience.

Easy to Integrate

Already have your own character and controller? Add building to your existing project instead of rebuilding everything around a template.

Your project. Your character. Your building rules.

Built for Real Gameplay

Combine systems into deeper loops:

• Gather -> Recipes -> Craft
• Resources -> Build Cost -> Place
• Support -> Load -> Collapse
• Hit -> Destroy -> Cascade

Self-Contained

Builder ships with everything it needs to run: the required Core layer and the NorthKit: Inventory System are included in the package - nothing else to buy. Already using NorthKit: Inventory System in your project? Builder integrates with your existing setup and will not overwrite it.

Extensible

Normal use requires no programming. For developers who need deeper customization, Builder exposes events, contracts and APIs for integrating custom gameplay and extending functionality.

NorthKit Ecosystem

Part of the modular NorthKit line - the same items, save system and skins carry across every package:

• NorthKit: Inventory System (Free) - the foundation for items, inventory, pickup/drop and storage.
• NorthKit: Survival System - complete survival gameplay.
• NorthKit: Builder System - base-building with structural integrity (this package).

Use the systems independently or combine them into a complete gameplay framework.

Note: the character shown in the promotional video is not included.

The demo scene uses a free CC0 character model.
