My Family House Builder Simulation Game Unity Source Code

My Family House Builder is a 3D open-world mission game built for mobile. The player navigates a real environment, drives vehicles to construction sites, interacts with NPCs, and completes building objectives across progressive levels. Each level delivers new missions — find the car, reach the location, give orders to the engineer, watch the house go up.

Complete Unity source code. Android and iOS included. Buy it, reskin it, publish it.

What Is My Family House Builder?

Open world. Real missions. A family home to build.

The player moves through a 3D environment using a D-pad joystick. Objectives appear on screen — reach a vehicle, drive it to the construction site, talk to the engineer NPC, give the build order. A minimap in the top left corner shows current position and objective direction with a green arrow.

Each level adds new construction objectives. Early levels cover simple tasks — find the car, drive to the site. Later levels expand the mission chain — coordinate multiple NPCs, manage different building stages and complete the full house construction sequence. The open world structure means the player navigates freely between objectives rather than following a linear path.

Key Features

These features were verified directly from the source code and confirmed through full gameplay:

• Open World 3D Environment — free roam grass and terrain environment, player navigates between objective locations without loading screens between areas
• Mission Objective System — on-screen objective text displays current task in real time, color-coded NPC names highlight interaction targets, multiple simultaneous objectives visible
• Minimap Navigation — top left minimap with green directional arrow guides player toward current objective location across the open world
• NPC Interaction System — engineer and family NPCs interact with the player to trigger mission steps, dialogue and order-giving mechanics built in
• Vehicle Driving Mechanic — player locates and drives vehicles to construction site destinations, car driving integrated into mission flow
• D-Pad Joystick Controls — four-direction D-pad in bottom left corner, built for mobile touchscreen play, full directional movement across the open world
• Level Based Progression — sequential mission levels, each level introduces new construction objectives and NPC interactions, difficulty scales through mission complexity
• Construction Simulation — house building progression tied to mission completion, player sees construction advance as objectives are fulfilled
• AdMob Integrated — banner ads, interstitial ads, and rewarded video ads pre-configured, update publisher ID and revenue starts from day one
• Android and iOS Support — single Unity codebase, build for both platforms independently
• Ready to Publish — stable, tested, production-ready for immediate store submission

Controls

• D-pad joystick — bottom left, four directional arrows, move character through the open world
• Interact button — approach NPCs and vehicles to trigger interaction prompts
• Minimap — top left, green arrow shows objective direction at all times
• Pause — top left button halts gameplay at any point

Simple mobile controls. Any player navigates the open world within the first session.
