Behavior tree plugin for ${pluginName}

## Installation

\`\`\`bash
npm install
npm run build
\`\`\`

## Usage

在编辑器中加载此插件：

\`\`\`typescript
import { ${pluginName.replace(/-/g, '')}Plugin } from '${pluginName}';
import { EditorPluginManager } from '@esengine/editor-core';

// 在编辑器启动时注册插件
const pluginManager = Core.services.resolve(EditorPluginManager);
await pluginManager.installEditor(${pluginName.replace(/-/g, '')}Plugin);
\`\`\`

## 多语言支持

本插件内置中英文多语言支持，使用简单的 i18n key 方式。

### 设置语言

\`\`\`typescript
// 设置为中文
${pluginName.replace(/-/g, '')}Plugin.setLocale('zh');

// 设置为英文
${pluginName.replace(/-/g, '')}Plugin.setLocale('en');
\`\`\`

### 翻译文件结构

在 \`src/locales/index.ts\` 中，使用扁平化的 key-value 结构：

\`\`\`typescript
export const translations = {
    zh: {
        'plugin.name': '插件名称',
        'plugin.description': '插件描述',
        'NodeName.name': '节点显示名',
        'NodeName.description': '节点描述',
        'NodeName.property.label': '属性标签',
        'NodeName.property.description': '属性描述'
    },
    en: {
        'plugin.name': 'Plugin Name',
        // ...
    }
};
\`\`\`

### 在代码中使用

\`\`\`typescript
import { TaskStatus, NodeType } from '@esengine/behavior-tree';
import { INodeExecutor, NodeExecutionContext, BindingHelper, NodeExecutorMetadata } from '@esengine/behavior-tree';

@NodeExecutorMetadata({
    implementationType: 'YourNode',
    nodeType: NodeType.Action,
    displayName: 'YourNode.name',
    description: 'YourNode.description',
    category: '自定义',
    configSchema: {
        propertyName: {
            type: 'string',
            default: '',
            description: 'YourNode.propertyName.description',
            supportBinding: true
        }
    }
})
export class YourNode implements INodeExecutor {
    execute(context: NodeExecutionContext): TaskStatus {
        const propertyName = BindingHelper.getValue<string>(context, 'propertyName', '');
        // 执行逻辑
        return TaskStatus.Success;
    }
}
