Keep cache from one state to another?

[ForgeableSum]

Is there a way to prevent Phaser from destroying the cache when going from 1 game state to another? I already tried:

game.cache.destroy = null;

 

I also tried setting clearWorld and clearCache (internal booleans) to false when starting the new state:

game.state.start("New State",false,false); 

 

And yet, the cache still gets wiped. I tried going through every instance (in Phaser) of cache.destroy and commenting it out ... yet still the cache does not carry over from 1 state to the next!

When you say cache... do you mean the thing that you load a bunch of images into in a preload state and then use in your main state, the assets cache? 'Cuz I know that works. Do you have a minimal example that reproduces this?

[ForgeableSum]

Yes, the game assets cache, e.g. game.cache._images. game.cache._json, etc. When you say "i know that works" are you saying that the cache does not automatically be destroyed when you go from one cache to another? What works? When I mean states, I don't mean going from preload to create, etc inside of a single state. I mean going from one state to a complete different state. I want one state to have access to the assets loaded in the preload of another state.

Yes, sorry, I meant "moving from one state to another does not empty the asset cache". My game, running Phaser 2.4.4, preloads in one state, has a main menu in a second, then plays in a third... all using assets loaded in the first preload state.

 

I'm kind of at a loss as to why that's happening for you, especially if you're commenting out all the "empty" and "destroy" methods and it's still happening. Can you make it happen in a minimal example on codepen or jsbin or something?

True clears world, and false keeps cache.

this.game.state.start('level-id', true, false);

True clears world, and false keeps cache.

this.game.state.start('level-id', true, false);

Isn't this the default behaviour? I think it has been so for several versions already - http://phaser.io/docs/2.4.4/Phaser.StateManager.html#start

If you call just

this.game.state.start('level-id');

you should get the same results.

Just to close the loop here, too: in the code sample you linked to, don't transition to the next state at the end of the preload function in Boot, do it at the end of create instead. "create" is only called when preload is complete.

 

That's how Blaster does it.
