Code:

// Globals go outside functions, but should only be 
// declared, not given values.
PImage[] MandMs;

void setup()
{
  size (800,600);
 
  //The graphics below are in my data folder
  //I want the array MandMs to be used globally or be
  //passed to subroutines that need it.
  PImage Green,Yellow,Red,Blue,Brown,Check;
  Red = loadImage("Red.jpg");
  Green = loadImage("Green.jpg");
  Blue = loadImage("Blue.jpg");
  Brown = loadImage("Brown.jpg");
  Yellow = loadImage("Yellow.jpg");
  Check = loadImage("Check.jpg");
  //Now define how big MandMs is.
  MandMs = new PImage[7];
  //And assign the values.
  MandMs[1]=Red;
  MandMs[2]=Green;
  MandMs[3]=Blue;
  MandMs[4]=Brown;
  MandMs[5]=Yellow;
  MandMs[6]=Check;
}

 
//I want this to be a subroutine that has access to the array MandMs
 
//since MandMs is global, dont' need to pass it. If you did 
// need to pass it, you'd use:
// void myFunc(PImage[] foo)
// and then use image(foo[m],i,j);

void myFunc()
{
  for(int i=0; i<800; i=i+50) {
    for(int j=0; j<600; j=j+50){
	int m = round(random(4))+1;
	image(MandMs[m], i, j);
    }
  }
} 

Guys,

Just to show I've used your advice I put the code I've developed so far below.

Now I'm stuck on how to deal with the mouse.

Before in METAL I had a procedure named GetAClick that I called when I wanted the program to  wait for a mouse click and then return with the x and y coords.

I'm not seeing a way to do this with Processing 0118.

Can you help me on this one?

Thanks for your time,
d ward

hey d,

here's a simple mouse click for you:

Code:

//Create an actual Point that you can reference
//Point is from the Java API (which you can use in Processing)
Point mousePoint = new Point(0,0);

void setup(){}

void draw(){}

void mousePressed(){
//Pass the current mousePoint into a function
//that updates its location
  setToMousePoint(mousePoint);
  println("x: "+mousePoint.getX()+", y: "+mousePoint.getY());
}

//Sets any given point to mouse coordinates
void setToMousePoint(Point p){
  p.setLocation(mouseX,mouseY);
}
