stickman animation in flex

I am trying to build a stickman in Flex who will a) move across the screen with speed- based on slider value b) do something different (jump/ sit down) when he reaches end of screen

I presume will need to switch between 3-4 images to simulate illusion of movement with parts of body 开发者_运维问答moving. would this approach be right? Are there any similar examples I can learn from?

It depends on how realistic you want it to look.

What you are saying could probably work, but if you wanted to get it looking/behaving really nicely I would recommend the book "ActionScript Animation." There were a couple of chapters in the book about kinetics that walked you through building a man that walked/jumped etc with sliders that could control not only his speed, but gravity, body segments size, etc.

I read the first edition that was on ActionScript 2 but there is a new one for ActionScript 3.
