Installation

Add to your manifest.json:

{
  "dependencies": {
    "com.amanotes.widget2d": "1.0.0"
  }
}

Quick Start

using Amanotes.Widget2D;
using UnityEngine;

public class ResponsiveTile : MonoBehaviour
{
    void Start()
    {
        var widget = GetComponent<Widget2D>();
        widget.size = new Vector2(100, 100);
        
        // Widget automatically resizes attached components
        // (SpriteRenderer, MeshRenderer, BoxCollider, etc.)
    }
}

Usage

Basic Widget Setup

public class TileVisual : MonoBehaviour
{
    private Widget2D widget;
    
    void Awake()
    {
        widget = GetComponent<Widget2D>();
    }
    
    void Start()
    {
        // Set size - auto-resizes components
        widget.size = new Vector2(50, 50);
    }
}

Custom Resize Behavior

public class CustomResize : MonoBehaviour, ISizeListener
{
    public void OnSizeChanged(Vector2 size)
    {
        // Custom resize logic
        transform.localScale = new Vector3(size.x, size.y, 1f);
    }
}

Screen Configuration

// Create Screen2D asset
var screen = ScriptableObject.CreateInstance<Screen2D>();
screen.width = 1080f;
screen.height = 1920f;
screen.referenceResolution = new Vector2(1080, 1920);

// Assign to widget
widget.screen = screen;

API Reference

Widget2D Component

public class Widget2D : MonoBehaviour
{
    public Vector2 size;              // Widget size
    public Screen2D screen;           // Screen configuration
    
    public void UpdateSize();         // Manually trigger resize
}

ISizeListener Interface

public interface ISizeListener
{
    void OnSizeChanged(Vector2 size);
}

Screen2D Asset

public class Screen2D : ScriptableObject
{
    public float width;
    public float height;
    public Vector2 referenceResolution;
}

Supported Components

• SpriteRenderer (sprite bounds)
• MeshRenderer (mesh bounds)
• BoxCollider (collider size)
• BoxCollider2D (collider size)
