I saw iphone game Zombieville USA’s picture on index page of Unity3d.com .
I think that Zombieville USA should be made by unity3d. Its 2d effect is very wonderful. its 2d Features are different from 2D gameplay Tutorial .
What kind of framework of unity3d can accomplish games like Zombieville USA?
is it SpriteUI? anything else?
Thank you very much in advance.

there is a lengthy thread where the zombieville developer explains how it works.
basically its a single boned mesh and each of the objects you see is a bone or a “sub skeleton”
these control bones then are what is beeing repositioned etc within unity through scripts which will make them look like they are their own thing
now by unity iphone with dynamic batching you likely don’t need that nor the spritemanager workaround any longer unless you want to use SpriteUI for the UI which requires SpriteManager too
dreamora, Thank you for your answer.
Is your meaning that all objects are 3d model ,not
2D images in this game?
I thought that it was made by 2D images like flash game. that’s wrong!
From the description, its a single 3D model.
You are always having 3D data. There is no 2D on the iphone thats hardware accelerated, nor does unity offer such functionality.
