Images + Atlases and Final Release Size Reduction

[kenshin]

Hi,

I would like to ask a question about image importing and atlassing.

Assume that, I have some 1000 of 1024x1024 images and I use %80 of them in game for 2D sprite animations(approx 4 GB animation source asset) and assume that with png compression those 4GB animations will be will be 1 GB in size when imported in unity.

In addition, as far as I know sprite collections also create an image. Assume that its size will be 1 GB also.

1. ist it true that my animatios will be 1 GB(from imported png image in unity) +  1 GB (2d toolkit sprite collection) roughly  (no use of dicing for to splain stuation clearly) = 2 GB for animations ?

2. if  first question's answer is yes, then there is redundant images, because I dont want to use those source images. I will just use sprites and I dont want them to be in the final release, because I have use sprite collection's images(atlases) and not the imported source images. is this possible(or already possible ) ?

3. Assume I use an 20 sprite(frame) animation (all from different collections) will there be a lag when first run the animation ? will it load them from disk and drop my fps and smoothnes of object ? If yes, need advice pls.

4. How many frames (assume 1 sprite in each sprite collection) can 2dtoolkit handle in 24 fps or 30 fps roughly. For example can I use total of 200 framed animations (200 sprites in 200 sprite collecitons) in ipad 2 or mini or .. ? just roughly answer from your experiences pls ?

5. To reduce image size, should I use color as transparency (for example magenta as background) when importing ?

6. Finally what dou you suggest to reduce final release size and how to manage big sprites with atlases ?

And .. this is a great product unikron made. thanks. keep up good work pls.

1. In unity, yes.
2. tk2d won't use the source images.
3. Likely, you should probably warm up the cache by playing the animation in the background / displaying the sprites at least once.
4. It sounds like you want video here? tk2d does sprites well, but 32bit Unity will run out of memory quickly.
5. Alpha = transparency, thats what we use.
6. Depends on what you want to do, 1000 1k images is a LOT of sprites, what kind of game is this?

I am very appreciated that  I had responses very very fast:)

I just want to understand the 2d limits. So i used fringe examples. I just evaluate to go 3d chars or old style choice for a fighter game.

As a conclusion at final build I can delete source images and It won't be problem for tk2d.

Thanks for help.

You shouldn't delete the source images, but tk2d will not include them in the build
