How to save the state of game

[kenta88]

Hi guys,

Here turin again

I would know if there are any techniques to save the state of game in babylon.js

I use a game object as a root of entire canvas (as described into learning babylon.js ebook).

I create an angular app and I would to change the route without loose the current game.

I thinking about saving the state inside the $rootscope and reload it when I need. But I'm not sure that is a good way.

Do you know any idea about it?

Thanks

Hello Kenta, 

The way to save the game state and game context is up to you. As it's different in each game, it cannot be created generically.
You'll have to implement it according to your game.

I would suggest isolating your game's state into a separate object, such as Game.savedState, which gets updated either in an interval or on demand. Things you could store in there could be

Game.savedState = {
    playerMeshDetails: {
        position: scene.playerMesh.position,
        rotation: scene.playerMesh.rotation
    },
    score: currentScore,
    someOtherPertinentInfo: data
};

Two options that come to mind would be:

1) Build an API that passes the information to a database that can store the object for a given game instance

2) Pass the object through the URI for example: https://jsfiddle.net/v62zdna7/2/

 

Option 2 is quick and dirty. Either way, it would make sense to reload your game, but if the state needs loaded, the object gets passed and set on load (or whenever you choose to do so)

 

Hope this is helpful, either way it's here for my reference

 

PS: I would not recommend trying to save the ENTIRE Game object that contains the engine, scene, etc. Do so though at your own risk

Are you planning on saving the game information on a database, or on the local client?

I created a method that save some information about position and other stuff inside local storage. This is enough for me. 

Do you have any different idea about it?
