Is Application.GarbageCollectUnusedAssets supported for iPhone? I couldn’t find any documentation on it. I did find this:

http://forum.unity3d.com/viewtopic.php?p=202038

Specifically I am trying to only load textures when they are needed and unload them when the textures are not needed. Can I do that using

  1. Resources.Load followed by Application.GarbageCollectUnusedAssets?

  2. Aren’t all the textures loaded at the start? Then do I first unload the assests that I’m not using by calling Resources.UnloadUnusedAssets?

actually its only supported on the iphone, not on the desktop

and its definitely in the documentations. i guess you just didn’t open the right ones. For iphone you must open the documentations that were installed when you installed unity iphone. they are not available otherwise

Right, its installed under Applications/UnityiPhone/Documentation on the computer I installed UnityiPhone on.

  1. So after I load a scene do I call Application.GarbageCollectUnusedAssets and that will remove all of the assests that aren’t being used?

  1. Do you know how much memory the base Unity iPhone engine takes up? I.E. is it around 20 MB?

I’m asking so I can figure out how much memory my app is taking up. If my app’s total memory is 35 MB, then I know I have 15 MB of assets, etc. and the remainder is the Unity engine.

if you run on .net 2.1, use networking and iphone basic around 17-19mb yeah

and you seem to forget that memory is not just code + assets but also the objects etc you create while running it.

I’m using iPhone Advanced verison 1.5. Do you know how much memory that uses?
