How do I switch scenes?

I tried to use AssetsManager as well as AssetContainer , but both of them work only with the scene currently being loaded

? Both constructors take the scene to work with as a parameter:

[…] Ah, I understand, you want to move some existing assets from one scene to another… Not sure it is possible. However, in your case, why don’t you load directly your assets in the main scene? Even if all the assets are not loaded yet, it won’t stop the scene to be rendered correctly with the assets already available.

@randle_mcmurphy

My initial idea was to load all those assets at the start of the game, before the “HomeScene” is displayed.

You can load your assets (the ones you want to load in “GameplayScene”) in “HomeScene” first, then wait for them to be loaded, then load your other assets. No need for two scenes for that.

Hi @randle_mcmurphy, can’t you use different AssetContainers to populate the one scene and/or different AssetsManagers for different scenes? They seem quite flexible in that regard, but maybe I’m not understanding your use case.

Yes, I can use different AssetContainers and/or AssetsManagers for different scenes, but then the player will need to wait for the “GameplayScene” to load assets.

@Pryme8

Im confused kinda, do you have all your scenes and assets preloaded? Or are you talking about cascading the scenes to the client and rending the first ready one then like toggling between different scenes?

What I want:

1. All the assets used in the “GameplayScene” are loaded at the start of the game (along with the few other assets used in “HomeScene”).
2. After the assets are loaded, “HomeScene” is shown.
3. When the player clicks the “Play” button, after a short transition effect the “GameplayScene” is shown (without any time spent to load the assets, cause they are already loaded).

@Pryme8

If that’s the case then just store them in an array as they come in and switch out which one is being used in your render loop by a selected Id?

Perhaps I should create both “HomeScene” and “GameplayScene” at the start of the game and when assets are loaded, only render “HomeScene”? I’ll keep a reference to the “GameplayScene” and when the player clicks the “Play” button, I’ll take out “HomeScene” and render “GameplayScene” instead.

Is this the recommended way to do this kind of task?

Yup I would do that as it could be easier to track what is going on in your use case.

[Pryme8]

Exactly! Glad I made sense… it was late when I responded and my brain was on meltdown.
