What's the problem? What are you trying to do with the mouse's position?
As it is now, we see that you have a sketch that draws a bunch of pentagons.
But we have no idea what it is you're trying to add to that!
What exactly are you trying to accomplish?

That said, mouseX, and mouseY always have the X and Y positions of the mouse.
You can assume they are read-only global variables.

hi thanks for the reply!

i would like to ad some form of interaction with the shapes. i was hoping that i could throw mouseX and/or mouseY somewhere and that it would start moving or growing. i've done this with basic shapes. for some reason i can't seem to get either to work on this sketch.

hopefully i could get the shapes to grow in size, or rotate, etc. ideally it would be individually. or if its easier then maybe all of them combined.

i loved doing the tutorials but i got stumped there and im running out of time.

the tutorial included adding the no loop, could that be the reason?

thank you!

1. void setup(){
2.   size (500,500);
3.   background(0);
4.   stroke(255);
5.   smooth();
6. }
7. void draw(){
8.   background(0);
9.   translate( width/2.0, height/2.0);
10.   for( int deg1=0; deg1<360; deg1=deg1+10){
11.     pushMatrix();
12.     rotate( radians(deg1) );
13.     translate(100, 0);
14.     rotate( map(mouseX, 0, width, 0, TWO_PI) );
15.     float polySize = 50 + map( (mouseY + (height/6.0 * ((deg1/10)%6))) % height, 0, height, 0, 50);
16.     polygon(5,polySize,polySize);
17.     popMatrix();
18.   }
19. }
20. void polygon(int sides,float xradius,float yradius ){
21.   float increment=int(360/sides);
22.   float rad1,rad2;
23.   for (float deg=0; deg<360; deg=deg+increment){
24.     rad1=radians(deg);
25.     rad2=radians(deg+increment);
26.     line(sin(rad1)*xradius,cos(rad1)*yradius,sin(rad2)*xradius,cos(rad2)*yradius);
27.   }
28. }

So... I may have taken quite a few creative liberties with this...
Anyway, if you want it to animate at all, you're going to have to remove the call to noLoop(), yes.
If you want them to rotate, it's helpful to position them with translates, rather than math, as that moves the origin to their centers (for easy rotation).
Their rotation and size values change based on the mouse's X and Y positions. I map the each position (which varies from 0 to width or 0 to height) to a different range with the map() function.

Awesome!! thanks man you've saved my day!! thank you. Heading off to class now, but looking forward to seeing how you pulled it off. thanks!
