If you want to make a 2d game your best bet is panels. Sprites don't animate and using a model with shiviting u. v. Points will be annoying and getting the collision detection to work the way a 2d game would work is also a lot of head aches. I went thru a lot of these problems recently in my 2d game and went from flat 3d to Panels only. Happy I did.
Ok, but I`m not sure how to do the collision detection with panels? Can you give me some idea please?
