Beating heart with variable heart rate? 1

[frozenpeas]

Okay everyone. Put your thinking caps on.

I need to create a beating heart. I need to be able to have control over the heart rate... and therefore, the speed at which the heart beats.

Any clever ideas?

What about making an MC of the "beat" (I presume you mean a heart beating, not an ECG readout?), and script it so that you can set the timing in between "beats" (the movieClip playing). For example, make the beat last 1/4 of a second (3 frames at 12 fps), and set an interval between each beat as 1/4 of a second (or thereabouts - it won't be exact) by using getTimer() to retrieve the number of milliseconds passed / 1000.

You could even make it more "realistic" by creating a beat interval and a pulse interval ... when the heart beats you get 2 beats close together, one for blood in and one for blood out, don't you? then there's a longer gap in between pulses. So set 2 wait periods, the second longer the the first, and alternate between the two!

I should really get a life now, shouldn't I ... ?

If you want any help, let me know and I'll see if I can come up with anything. Right now I'll just shuffle back into my box :/
