||||
## 🚀 Quick Start
|
||||
|
||||
### Option 1: View Demos in Browser
|
||||
Open `canvas_demos.html` in your browser for an interactive experience with simulated Nyash functionality.
|
||||
|
||||
### Option 2: Run with WASM (Future)
|
||||
```bash
|
||||
# Build WASM package
|
||||
cd projects/nyash-wasm
|
||||
./build.sh
|
||||
|
||||
# Start local server
|
||||
python3 -m http.server 8000
|
||||
|
||||
# Open demos
|
||||
open http://localhost:8000/canvas_demos.html
|
||||
```
|
||||
|
||||
## 📦 Box Architecture
|
||||
|
||||
### Core Canvas Boxes
|
||||
- **`WebCanvasBox`**: HTML5 Canvas drawing operations
|
||||
- **`CanvasEventBox`**: Mouse, touch, and keyboard input
|
||||
- **`CanvasLoopBox`**: Animation frame management
|
||||
- **`TimerBox`**: setTimeout/setInterval/requestAnimationFrame
|
||||
|
||||
### Supporting Boxes
|
||||
- **`RandomBox`**: Random number generation, probability
|
||||
- **`MathBox`**: Mathematical operations and constants
|
||||
|
||||
## 🎨 Technical Highlights
|
||||
|
||||
### Everything is Box Philosophy
|
||||
```nyash
|
||||
// Each component is a unified Box with consistent interface
|
||||
local canvas, events, timer, random
|
||||
canvas = new WebCanvasBox("my-canvas", 800, 600)
|
||||
events = new CanvasEventBox("my-canvas")
|
||||
timer = new TimerBox()
|
||||
random = new RandomBox()
|
||||
|
||||
// All operations follow the same Box patterns
|
||||
canvas.fillCircle(x, y, radius, color)
|
||||
events.onMouseClick(callback)
|
||||
timer.setTimeout(callback, delay)
|
||||
color = random.choice(colorPalette)
|
||||
```
|
||||
|
||||
### Advanced Features Demonstrated
|
||||
- **Real-time Animation:** 60fps game loops with delta timing
|
||||
- **Physics Simulation:** Gravity, friction, collision detection
|
||||
- **Color Science:** HSL color space, harmony algorithms
|
||||
- **Event Systems:** Mouse/keyboard input handling
|
||||
- **State Management:** Game states, UI state, persistence
|
||||
|
||||
### Performance Optimizations
|
||||
- Efficient particle system updates
|
||||
- Canvas drawing batching
|
||||
- Memory-conscious object pooling
|
||||
- Delta time-based animations
|
||||
|
||||
## 🔧 Development Notes
|
||||
|
||||
### Adding New Demos
|
||||
1. Create `XX_demo_name.nyash` in this directory
|
||||
2. Use established Box patterns for consistency
|
||||
3. Include comprehensive comments explaining Box usage
|
||||
4. Add entry to `canvas_demos.html` for web testing
|
||||
|
||||
### Box Integration Guidelines
|
||||
- Always use Box constructors: `new BoxName()`
|
||||
- Follow naming conventions: `camelCase` for methods
|
||||
- Include error handling for WASM/non-WASM environments
|
||||
- Document Box interactions in code comments
|
||||
|
||||
### Browser Compatibility
|
||||
- Tested on modern browsers with Canvas support
|
||||
- WebAssembly required for full Nyash runtime
|
||||
- Graceful fallback to JavaScript simulation
|
||||
|
||||
## 🌟 Future Enhancements
|
||||
|
||||
### Additional Demos Planned
|
||||
6. **Audio Visualizer** - `AudioBox` + frequency analysis
|
||||
7. **QR Code Generator** - `QRBox` + camera integration
|
||||
8. **Real-time Chat** - `WebSocketBox` + multiplayer
|
||||
9. **3D Graphics** - `WebGLBox` + 3D transformations
|
||||
10. **Camera Effects** - `CameraBox` + image processing
|
||||
|
||||
### Advanced Box Features
|
||||
- **`SpriteBox`**: Image loading and sprite animation
|
||||
- **`ShapeBox`**: Complex geometric shapes
|
||||
- **`TextDrawBox`**: Advanced typography
|
||||
- **`ParticleBox`**: Professional particle effects
|
||||
- **`AudioBox`**: Sound synthesis and playback
|
||||
|
||||

* CanvasEventBox - Canvas入力イベント管理Box
|
||||
*
|
||||
* ## 📝 概要
|
||||
* HTML5 Canvasでのマウス・タッチ・キーボードイベントを
|
||||
* Nyashから利用可能にするBox。ゲーム開発、インタラクティブ
|
||||
* アプリケーション開発に必須の入力機能を提供。
|
||||
*
|
||||
* ## 🛠️ 利用可能メソッド
|
||||
*
|
||||
* ### 🖱️ マウスイベント
|
||||
* - `onMouseDown(callback)` - マウスボタン押下
|
||||
* - `onMouseUp(callback)` - マウスボタン離上
|
||||
* - `onMouseMove(callback)` - マウス移動
|
||||
* - `onMouseClick(callback)` - マウスクリック
|
||||
* - `onMouseWheel(callback)` - マウスホイール
|
||||
*
|
||||
* ### 👆 タッチイベント
|
||||
* - `onTouchStart(callback)` - タッチ開始
|
||||
* - `onTouchMove(callback)` - タッチ移動
|
||||
* - `onTouchEnd(callback)` - タッチ終了
|
||||
*
|
||||
* ### ⌨️ キーボードイベント
|
||||
* - `onKeyDown(callback)` - キー押下
|
||||
* - `onKeyUp(callback)` - キー離上
|
||||
*
|
||||
* ### 📊 座標取得
|
||||
* - `getMouseX()` - 現在のマウスX座標
|
||||
* - `getMouseY()` - 現在のマウスY座標
|
||||
* - `isPressed(button)` - ボタン押下状態確認
|
||||
*
|
||||
* ## 💡 使用例
|
||||
* ```nyash
|
||||
* local events, canvas
|
||||
* events = new CanvasEventBox("game-canvas")
|
||||
* canvas = new WebCanvasBox("game-canvas", 800, 600)
|
||||
*
|
||||
* // マウスクリックで円を描画
|
||||
* events.onMouseClick(function(x, y) {
|
||||
* canvas.fillCircle(x, y, 10, "red")
|
||||
* })
|
||||
*
|
||||
* // ドラッグで線を描画
|
||||
* local isDrawing = false
|
||||
* events.onMouseDown(function(x, y) {
|
||||
* isDrawing = true
|
||||
* canvas.beginPath()
|
||||
* canvas.moveTo(x, y)
|
||||
* })
|
||||
*
|
||||
* events.onMouseMove(function(x, y) {
|
||||
* if (isDrawing) {
|
||||
* canvas.lineTo(x, y)
|
||||
* canvas.stroke("black", 2)
|
||||
* }
|
||||
* })
|
||||
*
|
||||
* events.onMouseUp(function() {
|
||||
* isDrawing = false
|
||||
* })

* CanvasLoopBox - アニメーションループ管理Box
|
||||
*
|
||||
* ## 📝 概要
|
||||
* ゲームや動的コンテンツのためのアニメーションループを
|
||||
* 管理するBox。requestAnimationFrame、フレームレート制御、
|
||||
* ループ状態管理を統一的に提供。
|
||||
*
|
||||
* ## 🛠️ 利用可能メソッド
|
||||
*
|
||||
* ### 🎮 ループ制御
|
||||
* - `start(callback)` - アニメーションループ開始
|
||||
* - `stop()` - アニメーションループ停止
|
||||
* - `pause()` - アニメーションループ一時停止
|
||||
* - `resume()` - アニメーションループ再開
|
||||
*
|
||||
* ### 📊 フレーム情報
|
||||
* - `getFPS()` - 現在のFPS取得
|
||||
* - `getFrameCount()` - 総フレーム数取得
|
||||
* - `getDeltaTime()` - 前フレームからの経過時間
|
||||
* - `setTargetFPS(fps)` - 目標FPS設定
|
||||
*
|
||||
* ### ⏱️ 時間管理
|
||||
* - `getElapsedTime()` - ループ開始からの経過時間
|
||||
* - `reset()` - タイマーリセット
|
||||
*
|
||||
* ## 💡 使用例
|
||||
* ```nyash

* TimerBox - JavaScript風タイマー機能Box
|
||||
*
|
||||
* ## 📝 概要
|
||||
* setTimeout/setInterval/requestAnimationFrameをNyashから利用可能にするBox。
|
||||
* アニメーション、遅延実行、定期実行を統一的に管理。
|
||||
*
|
||||
* ## 🛠️ 利用可能メソッド
|
||||
*
|
||||
* ### ⏱️ 基本タイマー
|
||||
* - `setTimeout(callback, delay)` - 指定時間後に1回実行
|
||||
* - `setInterval(callback, interval)` - 指定間隔で繰り返し実行
|
||||
* - `clearTimeout(id)` - タイマーをキャンセル
|
||||
* - `clearInterval(id)` - インターバルをキャンセル
|
||||
*
|
||||
* ### 🎮 アニメーション
|
||||
* - `requestAnimationFrame(callback)` - 次フレームで実行
|
||||
* - `cancelAnimationFrame(id)` - アニメーションをキャンセル
|
||||
*
|
||||
* ### 📊 時間測定
|
||||
* - `now()` - 現在時刻（ミリ秒）
|
||||
* - `performance()` - 高精度時刻測定
|
||||
*
|
||||
* ## 💡 使用例
|
||||
* ```nyash
|
||||
* local timer, id
|
||||
* timer = new TimerBox()
|
||||
*
|
||||
* // 1秒後に実行
|
||||
* id = timer.setTimeout(function() {
|
||||
* print("Hello after 1 second!")
|
||||
* }, 1000)
|
||||
*
|
||||
* // 500msごとに実行
|
||||
* id = timer.setInterval(function() {
|
||||
* print("Tick every 500ms")
|
||||
* }, 500)
|
||||
*
|
||||
* // アニメーションループ
|
||||
* timer.requestAnimationFrame(function() {
|
||||
* // 描画処理
|
||||
* canvas.clear()
|
||||
* canvas.drawRect(x, y, 50, 50)
|
||||
* })
|
||||
* ```
