ToonCrafter采用微内核架构设计，插件通过以下流程与主程序交互：

mermaid

插件元数据规范

每个插件必须提供标准的元数据描述：

const pluginMetadata = {
  id: "com.example.tooncrafter.interpolate-control",
  name: "高级插值控制器",
  version: "1.0.0",
  author: "Your Name",
  description: "自定义卡通动画插值曲线与速度控制",
  dependencies: {
    "tooncrafter": ">=1.0.0",
    "other-plugin": "~2.3.0"
  },
  hooks: ["beforeRender", "afterRender", "onUILoaded"],
  permissions: ["modifyAnimation", "accessFilesystem", "showUI"]
};

生命周期管理

插件完整生命周期包含以下阶段：

mermaid

核心API详解

动画控制API

`animate.interpolateFrames`

控制关键帧之间的插值过程，支持自定义缓动函数。

参数说明：

参数名	类型	必选	默认值	描述
frameStart	number	是	-	起始帧索引
frameEnd	number	是	-	结束帧索引
count	number	否	10	插值帧数
easing	string/Function	否	"linear"	缓动函数
curveParams	Object	否	{}	自定义曲线参数

使用示例：

// 内置缓动函数
toonAPI.animate.interpolateFrames({
  frameStart: 5,
  frameEnd: 15,
  count: 20,
  easing: "easeOutQuad"
}).then(result => {
  console.log(`生成了${result.generatedFrames}帧，耗时${result.time}ms`);
}).catch(error => {
  console.error("插值失败:", error.message);
});

// 自定义缓动函数
toonAPI.animate.interpolateFrames({
  frameStart: 0,
  frameEnd: 10,
  count: 15,
  easing: (t) => t * t * (3 - 2 * t), // 自定义三次缓动
  curveParams: { tension: 0.8 }
});

`project.loadAnimation`

加载动画项目文件并返回可操作对象。

参数说明：

参数名	类型	必选	默认值	描述
path	string	是	-	文件路径
format	string	否	"auto"	文件格式(json/gif/png)
loadOptions	Object	否	{}	加载选项

使用示例：

toonAPI.project.loadAnimation({
  path: "/data/animations/chapter1.json",
  format: "json",
  loadOptions: { skipThumbnails: true }
}).then(animation => {
  console.log(`加载成功: ${animation.name}, 共${animation.frameCount}帧`);
  
  // 操作动画对象
  animation.frames.forEach((frame, index) => {
    console.log(`帧${index}: ${frame.width}x${frame.height}`);
  });
  
  // 保存修改
  return animation.save();
}).catch(error => {
  console.error("加载失败:", error);
});

钩子系统详解

ToonCrafter提供丰富的钩子点供插件接入：

渲染相关钩子

// beforeRender钩子 - 修改渲染参数
toonAPI.hooks.register("beforeRender", (params) => {
  console.log("即将渲染动画:", params.animationId);
  
  // 修改渲染参数
  params.renderOptions.quality = "high";
  params.renderOptions.fps = 30;
  
  // 添加自定义滤镜
  params.filters.push({
    type: "colorAdjust",
    brightness: 1.1,
    contrast: 1.05
  });
  
  return params; // 返回修改后的参数
});

// afterRender钩子 - 处理渲染结果
toonAPI.hooks.register("afterRender", (result) => {
  console.log(`渲染完成: ${result.outputPath}, 大小: ${result.fileSize}KB`);
  
  // 自动复制到剪贴板
  if (result.success) {
    toonAPI.utils.copyToClipboard(result.outputPath);
  }
  
  return result;
});

界面相关钩子

// onUILoaded钩子 - 创建自定义界面
toonAPI.hooks.register("onUILoaded", () => {
  console.log("主界面加载完成，创建插件UI");
  
  // 创建工具栏按钮
  const toolbarButton = toonAPI.ui.createElement({
    type: "button",
    icon: "custom-interpolate",
    label: "高级插值",
    tooltip: "打开高级插值控制面板",
    onClick: () => showInterpolatePanel()
  });
  
  // 添加到主工具栏
  toonAPI.ui.addToToolbar("animation-tools", toolbarButton);
});

实战开发：5个实用插件示例

1. 自定义插值曲线插件

功能：提供12种预设插值曲线与自定义贝塞尔曲线编辑器

核心代码：

import { InterpolateControl } from './core/interpolate-control';
import { CurveEditorUI } from './ui/curve-editor';

class AdvancedInterpolatePlugin {
  private control: InterpolateControl;
  private editorUI: CurveEditorUI;
  
  constructor() {
    this.control = new InterpolateControl();
    this.editorUI = new CurveEditorUI();
    this.registerHooks();
  }
  
  registerHooks() {
    // 注册UI加载钩子
    toonAPI.hooks.register("onUILoaded", () => this.initUI());
    
    // 注册菜单项
    toonAPI.ui.registerMenuItem({
      path: "Edit/Interpolation/Custom Curve...",
      onClick: () => this.editorUI.show()
    });
  }
  
  initUI() {
    // 创建控制面板
    const panel = this.editorUI.createPanel();
    
    // 添加到侧边栏
    toonAPI.ui.addToSidebar("animation", panel);
    
    // 绑定曲线变更事件
    this.editorUI.on("curveChanged", (curveData) => {
      this.control.setCustomCurve(curveData);
      toonAPI.ui.showNotification("插值曲线已更新", "success");
    });
  }
  
  // 暴露API供其他插件调用
  getAPI() {
    return {
      setEasingType: (type) => this.control.setEasingType(type),
      getCurrentCurve: () => this.control.getCurrentCurve(),
      applyToSelection: () => this.applyToSelectedFrames()
    };
  }
  
  private applyToSelectedFrames() {
    const selection = toonAPI.project.getSelectedFrames();
    if (!selection || selection.length < 2) {
      toonAPI.ui.showNotification("请选择至少两帧", "error");
      return;
    }
    
    // 应用自定义插值
    toonAPI.animate.interpolateFrames({
      frameStart: selection[0],
      frameEnd: selection[selection.length - 1],
      count: 30,
      easing: (t) => this.control.calculate(t),
      curveParams: this.control.getCurveParams()
    }).then(result => {
      toonAPI.ui.showNotification(`已生成${result.generatedFrames}帧`, "success");
    });
  }
}

// 导出插件实例
export default new AdvancedInterpolatePlugin();

曲线编辑器界面：

class CurveEditorUI {
  createPanel() {
    return toonAPI.ui.createElement({
      type: "panel",
      title: "自定义插值曲线",
      width: 400,
      height: 300,
      content: `
        <div class="curve-editor">
          <div class="preset-curves">
            <select id="curve-preset">
              <option value="linear">线性</option>
              <option value="easeInSine">缓入正弦</option>
              <option value="easeOutSine">缓出正弦</option>
              <option value="easeInOutSine">缓入缓出正弦</option>
              <option value="easeInQuad">缓入二次方</option>
              <option value="easeOutQuad">缓出二次方</option>
              <option value="easeInOutQuad">缓入缓出二次方</option>
              <option value="custom">自定义贝塞尔曲线</option>
            </select>
          </div>
          <div class="curve-preview">
            <canvas id="curve-canvas" width="380" height="150"></canvas>
          </div>
          <div class="bezier-controls" style="display: none;">
            <label>控制点1: X <input type="number" id="cp1x" value="0.4" step="0.01" min="0" max="1"></label>
            <label>Y <input type="number" id="cp1y" value="0.1" step="0.01" min="0" max="1"></label>
            <label>控制点2: X <input type="number" id="cp2x" value="0.6" step="0.01" min="0" max="1"></label>
            <label>Y <input type="number" id="cp2y" value="0.9" step="0.01" min="0" max="1"></label>
          </div>
          <button id="apply-curve">应用到选中帧</button>
        </div>
      `,
      onMount: (element) => this.setupPanel(element)
    });
  }
  
  // 省略其他实现代码...
}

2. 批量处理自动化插件

功能：根据CSV配置文件批量生成动画序列

配置文件示例：

"input_file","output_file","start_frame","end_frame","interpolate_count","easing","fps"
"/data/frames/scene1-001.png","/data/animations/scene1.mp4",1,24,12,"easeOutQuad",24
"/data/frames/scene1-002.png","/data/animations/scene2.mp4",1,16,8,"linear",16

核心代码：

class BatchProcessorPlugin {
  constructor() {
    this.init();
  }
  
  async init() {
    // 注册菜单项
    toonAPI.ui.registerMenuItem({
      path: "File/Batch Process...",
      onClick: () => this.showBatchDialog()
    });
  }
  
  showBatchDialog() {
    // 创建对话框
    const dialog = toonAPI.ui.createDialog({
      title: "批量动画处理",
      width: 600,
      height: 400,
      content: `
        <div class="batch-processor">
          <div class="input-section">
            <label>配置文件:</label>
            <input type="text" id="config-path" readonly>
            <button id="browse-btn">浏览...</button>
          </div>
          <div class="preview-section">
            <h4>任务预览:</h4>
            <table id="tasks-table">

                  <th>输出文件</th>
                  <th>帧数</th>
                  <th>状态</th>
                </tr>
              </thead>
              <tbody>
                <!-- 将从CSV加载数据填充 -->

3. 交互式速度控制面板

功能：可视化调整动画速度曲线，实时预览效果

核心代码：

// 速度曲线编辑器实现
class SpeedCurveEditor {
  constructor() {
    this.canvas = null;
    this.ctx = null;
    this.points = [];
    this.selectedPoint = -1;
    this.animation = null;

    this.isPlaying = false;
    this.playInterval = null;
    
    // 默认速度曲线（线性）
    this.points = [
      { x: 0, y: 0 },
      { x: 1, y: 1 }
    ];
  }
  
  mount(elementId) {
    const container = document.getElementById(elementId);
    if (!container) return;
    
    // 创建画布
    this.canvas = document.createElement("canvas");
    this.canvas.width = container.clientWidth;
    this.canvas.height = 200;
    this.canvas.className = "speed-curve-canvas";
    container.appendChild(this.canvas);
    
    this.ctx = this.canvas.getContext("2d");
    
    // 添加事件监听
    this.canvas.addEventListener("mousedown", (e) => this.onMouseDown(e));
    this.canvas.addEventListener("mousemove", (e) => this.onMouseMove(e));
    this.canvas.addEventListener("mouseup", () => this.onMouseUp());
    this.canvas.addEventListener("mouseleave", () => this.onMouseUp());
    
    // 创建控制按钮
    const controls = document.createElement("div");
    controls.className = "speed-controls";
    controls.innerHTML = `
      <button id="play-preview">预览</button>
      <button id="add-point">添加控制点</button>
      <button id="reset-curve">重置</button>
      <div class="preview-frame">
        帧: <span id="frame-number">0</span>/<span id="total-frames">0</span>
      </div>
    `;
    container.appendChild(controls);
    
    // 绑定按钮事件
    document.getElementById("play-preview").addEventListener("click", () => this.togglePlay());
    document.getElementById("add-point").addEventListener("click", () => this.addControlPoint());
    document.getElementById("reset-curve").addEventListener("click", () => this.resetCurve());
    
    // 初始化绘制
    this.drawCurve();
  }
  
  // 省略其他实现代码...
  
  // 应用速度曲线到动画
  applyToAnimation(animation) {
    if (!animation) return;
    
    this.animation = animation;
    document.getElementById("total-frames").textContent = animation.frameCount;
    
    // 计算时间映射
    const timeMap = this.calculateTimeMapping(animation.frameCount);
    
    // 应用到动画
    toonAPI.animate.setTimeMapping({
      animationId: animation.id,
      timeMap: timeMap
    });
  }
  
  // 计算时间映射关系
  calculateTimeMapping(totalFrames) {
    const timeMap = [];
    
    for (let frame = 0; frame < totalFrames; frame++) {
      const t = frame / (totalFrames - 1);
      
      // 使用贝塞尔曲线计算映射值
      const mappedT = this.bezierCurve(t);
      const mappedFrame = Math.min(Math.max(0, Math.round(mappedT * (totalFrames - 1))), totalFrames - 1);
      
      timeMap.push({
        inputFrame: frame,
        outputFrame: mappedFrame
      });
    }
    
    return timeMap;
  }
  
  // 贝塞尔曲线计算
  bezierCurve(t) {
    // 简化实现，实际应使用贝塞尔曲线算法
    // 这里使用线性插值作为示例
    return t;
  }
  
  drawCurve() {
    if (!this.ctx) return;
    
    const ctx = this.ctx;
    const width = this.canvas.width;
    const height = this.canvas.height;

插件调试与测试

调试环境搭建

ToonCrafter提供专门的插件调试模式，支持源码映射与断点调试：

# 启动调试模式
npm run dev -- --plugin-dev

# 构建开发版本插件
npm run build:dev

调试工具使用

// 在插件代码中使用调试API
toonAPI.debug.log("插件初始化开始");
toonAPI.debug.warn("使用了实验性API，请谨慎");
toonAPI.debug.error("配置文件加载失败", error);

// 设置断点
toonAPI.debug.breakpoint();

// 性能分析
const profiler = toonAPI.debug.startProfiling("interpolation");
// 执行关键代码
profiler.stop();

自动化测试

创建测试用例文件 test/plugin.test.js：

describe("AdvancedInterpolatePlugin", () => {
  beforeEach(async () => {
    // 初始化测试环境
    await toonAPI.test.initialize();
    // 加载插件
    await toonAPI.test.loadPlugin("./dist/main.js");
  });
  
  test("should register all required hooks", async () => {
    const hooks = await toonAPI.test.getRegisteredHooks();
    expect(hooks).toContain("beforeRender");
    expect(hooks).toContain("afterRender");
  });
  
  test("should apply custom easing correctly", async () => {
    // 创建测试动画
    const animation = await toonAPI.test.createTestAnimation({
      frameCount: 10
    });
    
    // 调用插件API
    const result = await toonAPI.plugin.call("com.example.tooncrafter.interpolate-control", "setEasingType", "easeOutQuad");
    expect(result.success).toBe(true);
    
    // 应用插值
    await toonAPI.animate.interpolateFrames({
      frameStart: 0,
      frameEnd: 9,
      count: 9,
      easing: "easeOutQuad"
    });
    
    // 验证结果
    const frames = await animation.getFrames();
    expect(frames.length).toBe(10);
  });
});

运行测试：

npm test

插件打包与发布

生产环境构建

// webpack.config.js
const path = require('path');

module.exports = {
  mode: 'production',
  entry: './src/index.ts',
  output: {
    filename: 'main.js',
    path: path.resolve(__dirname, 'dist'),
    library: 'AdvancedInterpolatePlugin',
    libraryTarget: 'umd',
    globalObject: 'this'
  },
  module: {
    rules: [
      {
        test: /\.ts$/,
        use: 'ts-loader',
        exclude: /node_modules/
      },
      {
        test: /\.css$/,
        use: ['style-loader', 'css-loader']
      }
    ]
  },
  resolve: {
    extensions: ['.ts', '.js']
  },
  optimization: {
    minimize: true
  }
};

执行构建：

npm run build

打包为插件文件

使用ToonCrafter提供的打包工具将插件打包为 .tplugin 文件：

# 安装打包工具
npm install -g tooncrafter-plugin-packer

# 打包插件
tooncrafter-packer --input dist/ --output my-plugin.tplugin --meta package.json

发布到插件市场

准备插件图标（128x128px PNG）
编写详细的README.md文档
创建插件截图（3-5张）
提交到ToonCrafter插件市场

性能优化与兼容性

性能优化技巧

懒加载与代码分割

// 使用动态导入实现懒加载
async function loadHeavyModule() {
  const module = await import('./heavy-module');
  return new module.HeavyClass();
}

// 只在需要时加载
document.getElementById('advanced-feature-btn').addEventListener('click', async () => {
  const heavyModule = await loadHeavyModule();
  heavyModule.doWork();
});

缓存计算结果

class StyleTransferPlugin {
  constructor() {
    this.styleCache = new Map();
  }
  
  async getStyleFeatures(imagePath) {
    // 检查缓存
    if (this.styleCache.has(imagePath)) {
      return this.styleCache.get(imagePath);
    }
    
    // 计算特征
    const features = await toonAPI.effects.extractStyleFeatures(imagePath);
    
    // 存入缓存（设置10分钟过期）
    this.styleCache.set(imagePath, features);
    setTimeout(() => {
      this.styleCache.delete(imagePath);
    }, 600000);
    
    return features;
  }
}

Web Worker使用

// 创建Worker
const worker = new Worker('worker.js');

// 主线程发送任务
worker.postMessage({
  type: 'processFrames',
  frames: frameData,
  params: processingParams
});

// 监听结果
worker.onmessage = (e) => {
  if (e.data.type === 'progress') {
    updateProgress(e.data.progress);
  } else if (e.data.type === 'complete') {
    handleResults(e.data.results);
  }
};

兼容性处理

// 检查API版本兼容性
function checkCompatibility() {
  const requiredAPIs = [
    { name: "animate.interpolateFrames", version: "1.0.0" },
    { name: "project.loadAnimation", version: "1.1.0" }
  ];
  
  const compatible = toonAPI.compat.checkAPIs(requiredAPIs);
  
  if (!compatible) {
    toonAPI.ui.showNotification(
      "插件需要更新版本的ToonCrafter，请升级到1.2.0或更高版本", 
      "error"
    );
    return false;
  }
  
  return true;
}

// 功能降级处理
function applyInterpolation(params) {
  if (toonAPI.compat.hasFeature("advancedEasing")) {
    // 使用高级缓动函数
    return toonAPI.animate.interpolateFrames({
      ...params,
      easing: params.customEasing
    });
  } else {
    // 降级为基础缓动
    toonAPI.ui.showNotification(
      "当前版本不支持自定义缓动，已自动降级为线性插值", 
      "warning"
    );
    
    return toonAPI.animate.interpolateFrames({
      ...params,
      easing: "linear"
    });
  }
}
