# comparing two int values

Hi there.

I’m a Max MSP newbie and am trying to do something rather basic.

Using pictslider, I’ve constructed a 3×3 grid that will generate nine combonations of integer values (one for the left outlet and one for the right outlet), depending on where the mouse is located in said grid:

x1,y1
x2,y1
x3,y1

x1,y2
x2,y2
x3,y2

x1,y3
x2,y3
x3,y3

What object would allow me to evaluate the different pairs and generate a unique output for each one?

Example:
for pair 1,1 – output the value “1″
for pair 2,1 – output the value “2″
for pair 3,1 – output the value “3″

and so on…

I attempted it with the select, match and split objects but was unable to create the intended result. Is there some kind of IF/THEN comparator?

Many thanks!

if you have jitter you could use a 3 by 3 matrix that is loaded with desired values. PictCtrl would read the content of each cell.
the advantage here is that you can have a matrix of N planes which means that each cell can hold N values…
in this example the matrix is loaded with random values.

i was a little too fast in reading your email and oversaw you needed sequential numbers as output, here is a revised example :

#P window setfont “Sans Serif” 9.;
#P window linecount 1;
#P message 651 318 50 196617 0;
#P newex 651 295 62 196617 prepend set;
#P newex 647 264 51 196617 zl slice 4;
#P newex 671 207 20 196617 t b;
#P newex 695 207 114 196617 sprintf getcell %ld %ld;
#P number 785 159 35 9 0 0 0 3 0 0 0 221 221 221 222 222 222 0 0 0;
#P number 695 160 35 9 0 0 0 3 0 0 0 221 221 221 222 222 222 0 0 0;
#P user pictslider 695 50 100 100 4 4 4 4 SliderDefaultKnob.pct 1 SliderDefaultBkgnd.pct 1 2163 0 0 131074 1. 1.;
#P newex 534 241 123 196617 jit.matrix bob 1 char 3 3;
#P message 533 162 88 196617 0 1 2 3 4 5 6 7 8;
#P newex 534 183 55 196617 jit.fill bob;
#P connect 1 0 0 0;
#P connect 0 0 2 0;
#P connect 2 1 8 0;
#P fasten 8 1 9 0 693 287 656 287;
#P connect 9 0 10 0;
#P fasten 6 0 2 0 700 234 539 234;

if/then stuff can be done with the [expr] object, but i dont
think you want to convert your 9 numbers one by one, but
rather do some kind of mapping.

for only 9 coordinates i would eventually:

– multiply the horizontal values with 100,
– and add them to the vertical values,
– them map the results via [select 101 102 103 201 202 203 301 302 303]
– to messageboxes (1), (2), (3), (4), …

such an “addition” of the 2 elements in a list of integers
faster to calculate, route, and sort.

Thanks to all for the prompt, clear replies!

I’ll probably try all of these suggestions just for the sake of learning and let you know how it goes…and probably ask more questions too. ;)

Thanks again!
