How to load config.json separately

iso74 · November 10, 2022, 7:17pm

Hi,

is there a chance to load content of the config.json file separately?

E.g. all the assets, the application_properties, …
How is the scenes part processed?

thx

It’s doable but it depends on what you are trying to do. Your best bet is to export a PlayCanvas build and study how the loader (__start__.js) script boots the PlayCanvas application instance and then loads the config.json.

The required method is here, where all assets/scenes are loaded and prepared:

github.com

playcanvas/engine/blob/main/src/framework/app-base.js#L711

      
        
            }
            
            
/**
             * Load the application configuration file and apply application properties and fill the asset
             * registry.
             *
             * @param {string} url - The URL of the configuration file to load.
             * @param {ConfigureAppCallback} callback - The Function called when the configuration file is
             * loaded and parsed (or an error occurs).
             */
            configure(url, callback) {
                http.get(url, (err, response) => {
                    if (err) {
                        callback(err);
                        return;
                    }
            
            
        const props = response.application_properties;
                    const scenes = response.scenes;
                    const assets = response.assets;
