You got the hard part down then. The next step is just to divide the unit circle (TWO_PI) by the number of things to get an angle. Inside of a for loop you can multiply that angle by 'i' to place the things.

Hi thanks for the above example, its just what I needed, but I am still coming across problems with my patch.

I am trying to combine the above code with this example code, in an attempt to make an array of images (.jpgs) rather than ellipses.

Apologies for posting such a seemingly simple noob problem. I have tried lots of variations on the code and cant get it to compile, if anyone can direct me to the correct way of combining these, that would be so helpful..

Thanks
JB

1. PImage[] myImageArray = new PImage[5];
   
   void setup() {
     size(800, 800);
   
     for (int i=0; i<myImageArray.length; i++) {
       myImageArray[i] = loadImage( "pic" + i + ".jpg");
     }
   }
   

"cant get it to compile"
The code above seems OK, it should compile. What errors do you have? Can you show the whole code?

Hi. Heres the code I am working with, i think the problems in the int function and which attributes I choose to int first?
..or maybe my numThings attribute name?

Thanks for looking
JB

1. 
       int numThings = 10;
   int centerX, centerY;
   
   void setup() {
   
     size(400, 400);
   
     smooth();
     centerX = width/2;
     centerY = height/2;
     }
    
   PImage[] numThings = new PImage[5];
   
   
   void draw() {
       background(255);
       float thingX = centerX+cos(TWO_PI/numThings*i)*100;
       float thingY = centerY+sin(TWO_PI/numThings*i)*100;
           numThings[i] = loadImage( "pic" + i + ".jpg");
       for (int i = 0; i < numThings; i++) {
           
   
     }
   
   }
   
   

Hi
RE: The code above.
I am still having difficulties compiling this, can anyone see any obvious blunders I am making and advise?
Thanks
JB

There are a few problems:
- You have two global variables called numThings: int numThings and PImage[] numThings.  You need to rename one of them (most likely the array should be called things[]).  If you define all your global variables at the top of the sketch errors like this are easier to spot.
- You're loading images in the draw() function.  When you do this the images are reloaded every time the sketch is redrawn (60 times a second) which isn't what you want.  Do all your loadImage() stuff in setup().
- You have a for loop in draw() that has nothing in it and 3 of the lines in draw() reference the variable i that isn't defined until you get to the for loop so these commands won't work and the for loop does nothing.

Thanks for all you insightful input. I feel like I am getting closer, I have tiedied the code and been through the basic examples getting an understanding of the PImage function, but I still cant get past this first problem!
I have included my code again, it works with an ellipse, but I really dont know how to swap this ellipse last line code for my 5 images being called by PImage ?
Any help would be great,
Thanks
JB

1.     int numThings = 30;
       int centerX, centerY;
       PImage[] myImageArray = new PImage[5];
   
   void setup() {
     size(600, 600);
     smooth();
      centerX = width/2;
         centerY = height/2;
   
     for (int i=0; i<myImageArray.length; i++) {
       myImageArray[i] = loadImage( "frag" + i + ".jpg");
     }
   }
   
             void draw() {
         background(255);
         for (int i = 0; i < numThings; i++) {
           float thingX = centerX+cos(TWO_PI/numThings*i)*100;
           float thingY = centerY+sin(TWO_PI/numThings*i)*100;
           //float thingX = centerX+cos(TWO_PI/numThings*i+makeThemSpin)*100;
           //float thingY = centerY+sin(TWO_PI/numThings*i+makeThemSpin)*100;
           ellipse(thingX, thingY,104, 104);
         }
       }
   

image(myImageArray[i % myImageArray.length], thingX, thingY);
perhaps? (untested)
