Hey everyone

I have downloaded Eclipse and have the HelloP5 tutorial working. Now i am trying to get multiple files working.

I have two classes, both in there own files.

procesingTest which extends PApplet and is the same as the tutorial.

import processing.core.*;

public class processingTest extends PApplet {


public void setup() {


   size(200, 200);


   stroke(155, 0, 0);


   PrintHelloWorld testPrint = new PrintHelloWorld();
   print("Hello World"); // This works
   System.out.println("Hello World 2"); // This works

}


public void draw() {
   line(mouseX, mouseY, width/2, height/2);

}

}


And i have PrintHelloWorld

import processing.core.*;

public class PrintHelloWorld {

public void main() {


   // print("Hello World"); THIS DOESNT WORK


   System.out.println("Hello World 2"); // This doesn't appear but compiles

}

}

Now the lines

print("Hello World");
System.out.println("Hello World 2");  
   
works in processingTest but fails in the PrintHelloWorld class. The processing function print() doesn't work i could kinda understand but i'm not sure why the System.out.println() wouldn't?

And is there a way i can get print() to work. If not, does this mean other processing functions like fill() and rect() won't work?

Any advice would be greatly appreciated!

ahhh! *slaps head*,

So now i have named my constructor correctly

import processing.core.*;

public class PrintHelloWorld {
PrintHelloWorld() {
   //print("Hello World"); //THIS DOESNT WORK
System.out.println("Hello World \n3"); // This doesn't appear but compiles
}

}

Thanks for the link brsma, i did Java at uni, but that was  a year ago so i'm a bit rusty. I will brush up on my Java
However your reply doesn't really help me with my immediate problem of the print() not working. I want to use eclipse so I can easily hook my processing projects up to SVN.

The system.out.println() is working now (because i put it in a function being called), but i still can't use the print().

From errors i have had in the past with the Processing IDE I notice that classes are really an inner-class. Does this mean every class i make will also have to be an inner-class of the processingTest?

I have a little tutorial online here about using Processing in eclipse:

This is actually going to move to http://www.learningprocessing.com, but for now it's still at the above link.  Hope this helps!
