Title: does swapping a tk2dSprite's sprite mean you're using twice a much RAM?
Post by: peterbrinson on July 21, 2013, 04:17:18 am

My scene has 10 GameObjects, each a tk2dSprite.  Each one is based on a unique sprite/image and everything is arranged carefully in the scene editor. 
At scene start, there’s a 50/50 chance I want to swap each of these with a different set of 10 sprite/images. 

I’d like to only load 10 images into memory as they are very wide and tall (png’s). 

- If on ‘Start()’, I swap each of the 10 with different sprite/images, does that mean 20 images are loaded into memory, even for a brief moment? (I'm naive about how unused sprite/images unload, and if they do). 

Btw, these images are mostly set up in sprite collections by themselves because they are so big.

The sprites don't unload unless you destroy all instances of them and call "UnloadTextures" or Resources.UnloadUnusedAssets. As long as there is a reference to something in Unity, it will load in.

Yes.

I shouldn't have deleted my reply.  I asked if loading a new scene also unloads unused assets.  You can see his reply "Yes" above.
