MAX challenge: basic loops

Well thinking about this in a pure basic (not the language) programming way, the size of the circle is based on the distance of the mouse to the said circle. mousestate will tell you the current location of the mouse.which can be switched to a relative location on the max patcher window.

If I were you I would start with that object and trying to scale a single circle in the middle of a patcher window. Once you get it to work with one, duplicating that should be simple.

[counter] and [uzi] are the objects typically used to implement loops in Max/MSP

There are plenty of archived threads on this subject, although you may need to be creative to find a good search term to turn them up.

I'm wondering if Gregory has written a vignette or something on this. The early Max tutorials will also have a bit of coverage.

Thank you both.

I can do it in standard programming. It just takes two "for" loops, nested. It is MAX I am not familiar with. Uzi is hardly a standard term, so who knew.

I tried searching for loops but this is too general a term. Hence the question.

I am off to look at uzi then. But further pointers are welcome.

:)

Here are my feeble attempts. The questions are in the patch.

Thanks!

this is how I do nested loops in max using uzi:

ok just saw your new post after I posted my thing-- I'm no open gl (or jitter) guru, sorry!

No, Terry - super helpful! Here is my GL progess so far. Shall implement your loops next.

Terry, how can I output floats from your loop? Unless I am mistaken, they are integers and with small numbers they become zeros... Is there "cast" in MAX?

By default, mousestate reports global coordinates, but when you send the zero message, it uses the current mouse position as 0, 0.

For historical reasons, numbers are integers by default in Max. If you want calculations carried out in floating point numbers, most things take a float as an argument, which will cause calculations to be floating point. The int number box essentially does a cast to int.
