Introduction to Rapidly Prototyping Your Indoor Building Game

Developing simulation games like The Sims or Two Point Hospital presents unique challenges, particularly in implementing indoor building systems. Game developers often face several pain points:

Technical Complexities:

• Building a robust construction system from scratch is time-consuming
• Implementing precise grid-based placement mechanics
• Managing complex object collision detection
• Handling wall and floor connections seamlessly
• Creating intuitive room recognition systems
• Room validation and boundary detection
• Dynamic furniture placement rules
• Wall attachment systems for doors and windows
• Intelligent space organization algorithms

UI/UX Hurdles:

• Designing intuitive building controls
• Creating responsive preview systems
• Implementing undo/redo functionality
• Providing clear visual feedback for valid/invalid placements

These fundamental building mechanics can consume months of development time and resources - time that should be spent prototyping and refining your core gameplay ideas!

Indoor Room Build

When you enter the game scene, there are four offices can be used to build room. The center one has already unlocked. Other three offices are occupied by some buildings. You could buy the building to unlock the office. (Currently, shopping system has not been implemented, so you can unlock them without any limitation.) You can build rooms in the unlocked offices. There are two buttons on the tool bar. One is for settings, the other is for building room. In the room list, you could choose one to build.

Expandable Office Space System

Upon entering the game world, you'll find four distinct office spaces available for development. The central office space is immediately accessible, while the remaining three locations start as occupied properties. To expand your building area:

• Unlock new offices by purchasing existing buildings
• Access the unlocked spaces for immediate construction
• Expand your territory strategically

(Note: In the current version, the purchasing system is in development, allowing unrestricted access to all spaces)

The streamlined toolbar provides essential controls:

• Settings button for quick access to game configurations
• Build Mode button to enter room construction
• Comprehensive room catalog with various pre-designed options

Each unlocked office space serves as your canvas, ready for creative room layouts and custom designs. Simply select your desired room type from the catalog and start building your perfect office space.

Blueprint Mode & Room Construction

After you choose a room type to build. You will enter blue print mode. There will be a cursor on the office ground.

Expand Space

The default state is expand space when enter blue print mode. Or you can click the brush button switch to expand space state. Press mouse left button then drag to get the blue print framework of your room. Then you can still use this function to expand the base framework.

When you select a room type, you'll enter Blueprint Mode - an intuitive construction interface where a dynamic cursor appears on the office floor, ready for room placement.

Room Layout Creation

The system defaults to Expand Space mode upon entering Blueprint Mode, allowing you to:

• Click and drag with the left mouse button to define your room's blueprint
• Create custom-sized spaces based on your needs
• Preview the room's framework in real-time with a blue outline
• Visualize space requirements before confirmation

Expanding Your Design

You can easily modify your initial layout:

• Toggle Expand Space mode by clicking the brush tool
• Add to your existing framework by clicking and dragging from any edge
• Adjust room dimensions dynamically
• Fine-tune your space with precise control

The intuitive drag-and-drop interface ensures smooth and precise room creation, while the real-time preview helps you visualize your design before finalizing.

Space Modification & Design Rules

Reducing Room Space

Switch to Reduction Mode by selecting the eraser tool, enabling you to:

• Remove specific sections of your blueprint
• Fine-tune room boundaries with precision
• Modify existing layouts efficiently
• Reshape rooms to meet your design needs

Design Flexibility

The Blueprint Mode offers powerful customization through two complementary tools:

• Expand Space (Brush Tool): Add and extend areas
• Reduce Space (Eraser Tool): Remove and refine sections

Important Design Guidelines

While the system offers extensive customization, it follows a key architectural rule:

• All room spaces must maintain physical connectivity
• Split or disconnected areas require separate room constructions
• This ensures logical room organization and gameplay consistency

(Pro Tip: If you need disconnected spaces, consider creating multiple individual rooms instead of a single split layout.)

Advanced Blueprint Manipulation

Blueprint Repositioning

The system offers intuitive movement controls:
