Simulate a pendulum

Phew!
My head was about to explode!

OK, so I'm very late to this but with good cause... really... (I'm slow):

Barry, there is no "big" math in this and I did it mostly to get you away from using a repeat loop which should not be used when a send can do the trick.
...{snip}...:

Simon,

Yep; I understand finally about the "don't use the repeat loop":

Code: Select all

  if tSwing = true then send pendulus to me in 10 milliseconds

Does the same as the repeat loop and the mouseUp handler sets tSwing to true/false as the button is clicked.
Would I be inaccurate to call this recursion?

I'm trying to approach my project from a user interface issue first. The questions I'm asking myself are: What would provide the appropriate feedback for a musician? Just sound? Sound and lights? Sound and motion? If motion, what sort of motion. How does one provide visual feedback for 3/4 time? 4/4 time? 5/4 time? (9/8 time if you're playing Blue Rondo a la Turk. Any Brubeck fans out there?)

Thanks, Simon, and to everyone. I just asked a question and you all responded with a chapter in a LiveCode Tutorial manual. Pretty cool.

Yes.

As for what would be appropriate:
I don't think the swing of a pendulum on a metronome adds anything for the user. The pendulum was cool when I was a kid learning piano (or when the cat decided it was to be attacked) but only the sound was useful.

I would go for sound and/or light option. You can add more by adding emphasis on the first beat. Gosh, and since it's a program you can even add different sounds for fractional beats. What Fun!

Yep, this. Sound and light, a way to live adjust the interval. Simple and effective.

Okay! I hope I've put everyone's names in the "thank you". If I have not, forgive me; I'll fix it in version .02

Here's "Brubeck's Metronome". Completely open and unprotected as required by the Community Edition license. I'm not doing a standalone yet as there is undoubtedly more "stuff" that needs to be done. But this is, IMHO, a good start. I can see a bunch of redundant code as I have each time signature calling a different handler. However, it is quite simple to debug in its present state and that's more important for anyone grabbing this stack who has not been part of this thread.

Comments and suggestions gratefully accepted.

Thanks,
Barry

Well for me the image sphere.png ended up on top of the buttons, that didn't work for me
I liked the use of setting the loc rather than using a move. I think out of the corner of the eye the abruptness of the motion gives better information.

Great!

D-oh! I imported a large graphic, re-sized it, but didn't realize that it would then be re-sized -back- to the original size when the stack was re-opened. Okay; I re-sized it in Preview, then imported that png into the stack. Here's version .02.

Barry

EDIT: Probably could have just locked the size and position, right?

Very nice! Thanks for sharing it.

Hopefully, you can find something useful in it.
