What is loaded into memory?

The whole game - or just the current layout?

Right now the whole game, but we have plans to load by layout.

Load by layout maybe improve performance, right Ashley ??

Because when i write code for other layout, but it's still effect in runtime even it's not in current layout. (sry for bad E).

farsmile90 - no, it will not improve performance, it will only save memory.

Thank ashley :D

farsmile90 - I might be misunderstanding you, but just in case - code from other layouts, while in memory, does not run unless included, so don't worry about code from other layouts hitting the framerate.

A lot of memory if your other layouts use a bunch of different sprites, I'd imagine.

so don't worry about code from other layouts hitting the framerate.

Not unless they're included. But any data - tiled backgrounds, sprites, sfx I guess, will be held in memory all the time at the moment. This is why you get high memory usage warnings from the browser (or at least I do)
