I need to make a practice tree using flash, it basically needs to run a simple animation and will require the player to click a button when the light turns green. It needs to show the reaction time for how long it took them to click after the light went green. There needs to be a few variables that make the equation for the delay time, like roll out and that variable needs to be changeable in a simple text box. I don't want anyone to do it for me, that's too much to ask but could you guys help point me at the right tutorials and explain what I will need to do to accomplish this? I'm a web develop and know html,css,php and mysql so I may be able to adapt to this fairly easily.
Thanks!
