Interface SubResourceLoader

Resource-Loader that actually ask the browser for resources (like loading an PNG or TXT file) should use this method to support rootPath.

USE this only for actual browser resource access.

If request(...) returns a null value that might be a valid result of a resource.

If in doubt the state of a resource can be queried here.

IMPORTANT

Don't use this function to decide weather you have to load a sub-resource or not.

Always use loader.request() for all sub-resources you need.

Use this to request one or more sub-resources your loader format needs.

Example could be:

sheetConfig = await mySubResLoader.request(['json:mySpriteSheet.json']);
const images = await mySubResLoader.request(sheetJson.images);
// now sheet config & images are there to create the object
