It would help if you give us some numbers and more details about your canvas sizes and the nature of your game. Is it a single screen or a scrolling game (because you created your batches on load and did not change them anymore)? How many tiles per layer, size of the tiles, size of the tileset (i.e....

The devil is in the detail. To call into constructors of parent classes you need to call them like so ClassB.super.new( self, x ) This is, because ClassB etc. are class instances and when you use super:new and not use the explicit self of the current scope, you call those upper constructors with the...

Never mind ... life's to short for these nosense.

I'd love to hear an actual reason with, maybe an explanation why and how something else works the same way, instead of just a phrase of opinion

Well IMO the actual value of such a format (if I don't get anything wrong about it in general) is that you for sure would not want to decode all the frames of an animation upfront into textures/texture atlases but on demand (code controlled) as you use the animation. As already written, think of any...

I can easily imagine games where such formats would be a decent option compared to regular animsheets. Like all kinds of partialbackground/layer/item etc. animations for point & click adventures, visual novels, hidden object games etc. Of course you can use every frame as a decompressed one on textu...

This is such a cool and unique idea - I really like it.

Haven't used it so far, but I hope I'll at some point. Thanks for the update.

You can use imageData:getString and use the result with data.encode to get a base64 encoded string. Later on just reverse the operation with data.decode and image.newImageData
