Environment
Environment-Toolbar Buttons
The toolbar buttons allow you to run and stop programs,
create new sketches, open, save and export:
1. Run . Compiles the code, opens a display window,
and runs the program inside.

2. Stop Terminates a running program, but does not
close the display window.

3. New Creates a new sketch.

4. Open Provides a menu with options to open files.
Another way of opening files is dragging and the file
icon to text editor area or processing icon.

5. Save Saves the current sketch to its current location.

6. Export Exports the current sketch as a Java applet
embedded in an HTML file.
Your First Piece of Code
void setup(){
size(200,200);
}

void draw(){
background(125);
float x=mouseX;
float y=mouseY;
println("Mouse x=" + x + "..... Mouse y=" + y);
line (x,y,100,100);
}
Environment-Menu Bar
The menus provide the same functionality as the tool
bar in addition to actions for file management and
opening reference materials.
Environment-Menu Bar-Default Examples
Under Examples you can find already made codes that you
can use as the base of your experiments and achieve the
desired result by changing these base codes.

This is what programmers call hacking. Meaning that you do
not start a piece of software yourself. You use other’s
software and change parts of it, to make it work your way
Hacking the Default Examples
For example lets go to examples , under basic, under
transform, choose arm, and run the code.
Hacking the Default Examples
Let’s say we want the background color white and we want to
double the size of the applet.
Hacking the Default Examples
size(400,400);
Hacking the Default Examples
background(255);
