Getting Object to Pulse/Blink Repeatedly On/Off

Jun 30, 2012 6:07 AM

Hi,

 

I am learning game type animations using a pong-style tutorial: http://as3gametuts.com/2011/03/19/pong-1/

 

Source FLA: https://www.box.com/shared/co3bn7aeey22ki6r22tf

 

Very nice tutorial!

 

For an eLearning lesson, I need to add a flashing/blinking/pulsing effect to the "ball" and need it to repeatedly flash/blink/pulse at a slower pulse (every 500 ms) than the pulsing that would be achieved by:

 

ball.visible = !ball.visible; (I also tried using setInterval with this visible=!visible and got too rapid a flashing, not able to get 500 ms).

 

Not sure how to achieve this? (Would prefer, if possible, to achieve this effect all by scripting in a single frame, rather than multiple frames.

 

Any help appreciated.

 

Regards,

    You should show what you did for the setInterval attempt.

    Hi Ned,

     

    Been playing around with this some more and can get it to work:

     

    function pulsate():void

    {

    ball.visible=!ball.visible;

    }

    setInterval(pulsate, 500);

     

    But, when I try to clearInterval, that's when it gets "dicey." I set up a uint var (var myInterval:uint=setInterval(pulsate,500);) so I can clearInterval(myInterval);

    Then, each time I reset the game animation (start over), seems the pulsing gets faster and faster. Must have to do with where I am putting the scripts or possibly calling them twice.

     

    After more experimenting, decided to use a Timer instead, which works better for this project.

     

    Regards,
