UI System Core

A reusable, config-driven UI management system for Unity. Provides screen lifecycle management, popup handling with priority queues, transition animations, and an editor tool for scaffolding new screens/popups.

Features

• Screen Management — Show/hide screens with transition animations, history stack, and back navigation
• Popup System — Priority-based popup queue with blocker panel
• Config-Driven — Per-screen behavior (HUD visibility, input mode, history exclusion) configured via UISystemConfig ScriptableObject
• Transition Overrides — Define custom transitions between specific screen pairs
• String-Backed IDs — ScreenId/PopupId structs wrap strings; game project generates enums via editor tool
• Input Abstraction — IUIInputHandler interface decouples from InputSystem
• Editor Tool — Tools > UI System > UI Creator scaffolds screen/popup classes and auto-updates enum files

Setup

1. Create a UISystemConfig asset: Create > UI > UI System Config
2. Create transition assets: Create > UI > Screen Transition
3. Add UIManager MonoBehaviour to a scene object and assign the config
4. Implement IUIInputHandler in your game project
5. Call UIManager.Instance.Initialize(yourInputHandler) at startup

Game Project Integration

Implement IUIInputHandler for your input system and create a setup script that:

• Initializes the input handler
• Calls UIManager.Instance.Initialize(inputHandler)
• Sets UIManager.Instance.OnCancelPressed for game-specific cancel routing
