The Android animation tools are mostly pointed at animations that can be performed by making graphical transformations on a single scene: making a page turn, wipes, fades, etc. This is what Android calls "tweened" animation. I think you are thinking of something they call "frame-by-frame" animation. The Android tool for managing this is a Drawable: http://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html. It is pretty limited... I don't think you'll want to base a game on it.
Erasing the old shape and drawing the new one is pretty much how you do a 2d animation. 2-d drawing happens on a Canvas. There are a lot of ways to optimize the process. Be careful, though, because the way Android does basic graphics changes a lot, for Honeycomb. Things that used to be optimizations (in particular, composing backgrounds and saving them as bitmaps), may actually slow things down. Probably the fastest way to draw uses OpenGL and the SurfaceView. It's like learning an entirely new, fairly complex, machine language. It might be overkill for a simple 2-d game. -blake Programming Android, FTW! http://oreilly.com/catalog/0636920010364 On Sep 3, 9:42 am, Tobiah <[email protected]> wrote: > I want to make a vector style 2d video game.
