   Currently I'm using a different PNG file for each Sprite. Let's say most of these are about 8KB. And I'm planning to have about 500 of them spread out on 10 levels. This will make the app 4MB big only for these images which will be too much.

   1. Do you guys use different PNGs for this number of files?.

   2. Performance doesn't seem to be an issue yet. But If it were, I should look into AtlasSprites and SpriteSheets, right? (the sprites are not used for animations though). Could this help in any other way to reduce the overall size used for images?

   3. Also, I'd like to know if it's possible to reuse a PNG file to create different Sprites with rotated versions of the original file without using actions.

   Thanks

   1. For 500 sprites? no.

   2. Even if you dont need it to make your gameplay run faster, you should look in to AtlasSprites bc it will be faster on startup than loading 500 individual images.

   3. Not sure what you are asking. Load the images pointing in one specific direction, and then rotate the sprite itself to where you need it to point.

   Hey Codemattic, thanks. I'm diving into spritesheets next thing.
   Would u say is a good aproach to group the pngs on same sizes(most of then can) and then do a sheet with a row for each size group?

   If you have many that are the same size, lay them out in a grid bc its easier to manage. If you are using pvrtc give a 4 pixel buffer between each sprite. But other than that - whatever makes the most sense to you and lets you fit the most on one texture!

   I usually group them from a usage point of view, so if I have some images that I only load in a few scenes, I group them together.

   All to try to load as few images per scene as I can.
