Elevator Simulation System (Unity)

Real-world elevators follow strict rules: they move between discrete floors, respond to user input, and operate with predictable timing. The goal of this project was to simulate this behavior in Unity in a way that is interactive, reliable, and easy to extend, rather than focusing on visual effects or gameplay.

I designed the elevator as a logic-driven interactive system, separating concerns such as movement, user input, and behavior control. The focus was on building predictable, real-world-like behavior using Unity’s update loop and scripted control, instead of physics-based movement. The system responds to floor selection input, moves smoothly between predefined floor positions, and enforces timing constraints to mirror how an actual elevator behaves.

Discrete floor-based elevator movement with accurate stopping positions

Interactive floor selection controls

Controlled, time-based vertical movement (non-physics driven)

Clear separation between control logic and movement behavior

These choices ensured the system remained easy to debug, reason about, and expand.

Designing interactive systems benefits from clearly separating logic, movement, and input handling

Time-based movement provides more predictable behavior than physics-based solutions for simulations

Even simple real-world systems require careful rule definition to feel believable and responsive

This project strengthened my understanding of building structured interactive systems in Unity rather than purely visual experiences.
