Class AcCmLoadingManager

Centralized loading manager that handles and tracks multiple loading operations.

This class manages the loading state across multiple file operations, providing progress tracking, error handling, and URL modification capabilities. A default global instance is created and used by loaders if not supplied manually.

Separate loading managers can be useful when you need independent loading progress tracking (e.g., separate progress bars for different types of resources).

Example

import { AcCmLoadingManager } from './AcCmLoadingManager'

// Create a custom loading manager
const manager = new AcCmLoadingManager()

// Set up callbacks
manager.onStart = (url, loaded, total) => {
  console.log(`Started loading: ${url} (${loaded}/${total})`)
}

manager.onProgress = (url, loaded, total) => {
  console.log(`Progress: ${url} (${loaded}/${total})`)
}

manager.onLoad = () => {
  console.log('All loading completed!')
}

manager.onError = (url) => {
  console.error(`Failed to load: ${url}`)
}
