Unity Bootstrap (2D Sim)

1) Create project (Unity Hub)

• •Use latest Unity LTS.
• •Template: 2D (URP) if you want lighting/post; otherwise 2D Core.
• •Enable packages early: Input System, TextMeshPro.

2) Git setup checklist

• •Add a Unity .gitignore (ignore Library/, Temp/, obj/, Build/, Logs/).
• •Commit a clean baseline after first project creation.

3) Folder structure (recommended)

• •Assets/_Project/Scripts/{Core,Gameplay,UI}
• •Assets/_Project/Scenes
• •Assets/_Project/Prefabs
• •Assets/_Project/Data (ScriptableObjects)
• •Assets/_Project/Art, Assets/_Project/Audio

4) Minimal runtime scaffold

• •BootScene:
  • •Loads config ScriptableObjects
  • •Loads save (if exists) or creates new state
  • •Loads GameScene
• •GameScene:
  • •Has GameController with:
    • •Tick loop (1 sec) + time scale (1/2/6x)
    • •Hooks for UI to call commands (build, assign, upgrade)

5) Next step

• •After this, use unity-migration to map and port the existing JS systems.
