Load and Unload Texture Atlas

[Siddharth3322]

I want to know that when texture atlas are loaded and unloaded in 2d Toolkit?
I am experience 2d programmer of AndEngine in that I have way to handle manually each texture atlas. But in 2d Toolkit I don't know same thing.

Basically as per my consideration new graphics are loaded when new scene is created and unloaded when scene is destroyed.
I know that it is pretty broad question but I want to know about basic working of the tool  so that I can define my further work strategy.

Its loaded the same way anything works in Unity. It gets loaded when the scene is loaded, unloaded when you load a new scene. It is uploaded to the GPU the first time it is visible and renders.

If I want to unload some of the texture then is it possible?
If yes, then please guide me in this. Any link describing that content become enough to me.

Check the documentation. You can call UnloadTextures on the sprite collection to unload all the textures.

Or delete the sprites, and call Resources.UnloadUnusedAssets.

Based on requirement if I want to load collection again then how to do it?

[unikronsoftware]

Depends on what you do.
Please search the forums - there are so many ways of doing this and this has been covered numerous times.

Ok, First I will read some posts then I will ask if I don't able to understand any concept.

If I create a sprite collection and does not create any sprite from it then it gets loaded into GPU or not?

[unikronsoftware]

Yes. This is how everything behaves in Unity. tk2d doesn't do anything special.

Thanks for your reply. Previously I am working with Andengine.
I don't have more experience with core unity principle also. I want to know more about this so where I can able to get more information?

If it is a core unity feature then I also want to know about it so that I can able to grab working of unity engine.
