2.5: Basic Q about Animation and GameEngine

I am fairly new to Blender 2.5.

  1. I can set up a basic keyframe animation, and would like to add some physics like gravity-influenced object.
    Whenever I switch to Blender-Game, my object falls, but my animation no longer runs.
    What am I doing wrong?

  2. How can I give my falling object an initial (horizontal) velocity? So, it behaves like a thrown stone under the influence of gravity.

  3. Details: I am working on a small clip of a roulette game. I set up the spinning roulette table with keyframed animation. Now I want to add a sphere - thrown into the kettle and spinning inside - this is where I thought I would use gravity and collision.

Thank you,
Reinhard
