Creation of a pendulum with dynamic parameters in Flash - Page 8

How to dynamically modify the value of the variables

Last part of this tutorial consists of understanding how to give interactivity to the movie, dynamically modifying the value of the implicated variables. In order to catch up this result we will use the 5 buttons over listed.

Restart button

The restart button just will serve to restart the pendulum motion, once stopped, or in any other moment: its duty will be therefore to bring back the a variable to its initial value. In order to make that, we must add the following action to the button instance to the inside of control panel movie clip:

on (release) {
  a = 1;
  }
