    Pretty new to flash, noticed everyone is using this stuff, Like friction gravity, and so on.

    Is there a good back or a list of commands, or more FLA's on this.

    Thanks.

    There aren't really any pre-built Flash commands to handle this stuff, but most you can just use mathematical formulas to mimic friction, gravity, etc.

    For example, if you want an object to decelerate due to friction, you could set up a "speed" variable and multiply it by a value less than 1:

    speedx = speedx*0.97

    That will slowly reduce the speed of an object. Then, when you apply that speed to an object's location:

    ball._x = ball._x + speedx

    The ball will move by a smaller and smaller distance with each time this script is executed.

    You can find some FLA examples at:

    under motion studies.
