Bouncing on a Trampoline

I often get hung up on explaining how I make my clown “bounce” on a trampoline in the Circus game that I use in my XNA presentations.  I know I introduce some basic trigonometry that we’ve all long since forgotten.  Considering my lack of engineering degree and poor grades in trig, I always assumed that everyone else in the room would just get it and I could easily move on.

I’ve not always found that to be the case, however.  It turns out, what I am doing seems a little magical to some people and the whole point of my talks is to make game development easy to understand and take the mystery out of it.

So let’s look at how we make a clown a bounce on a trampoline.
