Apply newton's 1st law to the situation.  Force is reapplied in the direction from the center of the sphere to the point where the irregular object touches it.  Then because of the 3rd law your sphere will move backwards in the opposite direction.  This should make the irregular object have a reflection pattern from the vector it was ...

Simply turn the car until Math.Atan((Car.Y-WayPoint.Y)/(Car.X-WayPoint.X))==0

Sometimes Apps are more fun than more complicated projects.  Personaly I have spent more time playing Blackjack then Halo :).

You could also try your local library (computer books are under call number 5.1333). Or online free tutorials.

Vista does not like homebrew in general.  If this is a major problem you probably should upgrade (or downgrade) back to windows XP.

If you wan choas then mabie you should have the color vary.  Perhaps randomise Red and Yellow Values to produce a set of oranges?

please allow me to be more specific.  I need to be able to add textures to the render target with the same abilities as spritebatch.draw (I.E. rotation and scaling) is there a way to do this?  I have used many other launguages that do allow this.  For example the code in BASIC would be SetBuffer(ImageBuffer(buffer)).  Thank You.

Is there a way to draw to buffers durring runtime.  I have several scaled and rotated texture2ds (by different amounts) that I need to make into a single texture.  Does anyone know a function to do this?  Thank you for your time.

Texture2D target; target = Content.Load<Texture2D>("target");         spriteBatch.Begin(); spriteBatch.Draw(target, Vector2.Zero, Color.White); spriteBatch.End(); No shader needed.
