Climate Town

Game Programmer

A touchscreen town-management game with 100 days to reduce the town’s carbon footprint while keeping residents’ support.

My contribution

I built the core gameplay systems, including touch camera controls, configurable building upgrades, object selection, UI menus, and online leaderboards. I also implemented the game’s state flow, refining interactions, resets, and performance for the museum touchscreen experience.

01 / Touch interaction

Camera Controls

Explore the town through touch gestures, with mouse and keyboard support.

Pan, pinch, and rotate

I built the camera controls with Unity’s Input System. Input actions start and stop movement routines, supporting touch, mouse, and keyboard controls together.

  • Dragging moves across the town. The distance and angle between two touches control zoom and rotation.
  • Camera movement pauses during menu interaction and selection transitions, so scrolling an upgrade list does not move the town behind it.
  • I added on-screen zoom and rotation buttons alongside the gesture controls.

02 / Gameplay data & configuration

Upgrade System

Configure the town’s choices and their effects through reusable object data.

One system for different objects

I built a ScriptableObject-based upgrade system, using Unity data assets to define each interactive object’s options and starting state.

  • Each option stores its name, description, goodwill requirements, carbon impact, and goodwill effect. Those values populate the menu and update the town’s stats.
  • Purchase and sell actions can enable, disable, or replace related options, keeping mutually exclusive choices consistent.
  • I connected upgrades to scene objects so buying an option also changes the town’s visible buildings and features.

03 / Gameplay & interface integration

Selection & Menus

Connect a tap on the town to the right view and controls.

From a tap to a decision

I connected object selection to highlights, camera transitions, and contextual menus. Selecting a new object clears the previous selection before opening its controls.

  • Touch duration and pointer movement distinguish a tap from a drag. Selection is blocked over UI and during camera transitions.
  • The scrollable upgrade menu reads the selected object’s data to display available choices, their costs, and their effects.
  • I built the power-grid menu with five linked sliders that keep electricity production at 100%. Applying changes updates carbon and goodwill; closing without applying restores the previous mix.

04 / Exhibit lifecycle & online services

Game Flow & Leaderboards

Take each visitor from the idle town to a completed run and an online score.

I implemented a state machine to coordinate attract mode, game setup, play, success, and failure. Starting a new run resets the town’s stats and upgrades, while completing 100 days submits the result to the online leaderboards.

Individual scores, shared totals

I integrated Unity Authentication and Leaderboards to give each visitor a fresh anonymous session without an account sign-up.

  • Load the top four player scores and generated player names into the exhibit UI.
  • Submit the final goodwill score after a successful run, then update the shared carbon and goodwill totals.
  • Return to attract mode with a roaming camera and configured upgrades, ready for the next visitor.
