Hi
There are a couple of ways to go about it, if you want to use actual scene files a common pattern is this:
// load a first simple scenewade.loadScene('firstScene.json', true, function(){ // first scene has been loaded // preload a second scene (this means it will be loaded asynchronously without blocking the execution of the first scene) wade.preloadScene('secondScene.json', false, function() { // second scene has been loaded, do something here }, true); // true means you want to remove any objects from the first scene before adding those from the second scene});
