Today’s in-class code can be found here.

Processing examples for 9/12 can be found here.

What we’ll go over:
– questions on homework (now due Wed)
– explanation of translate and scale
– subroutines explained more fully (in, out args)
– more about variables (types, final, static, arrays)
– input: mouse, keyboard, audio, time/date

You’ll find today’s example code files here.

Here are some notes about what we’ll be going over in class 9/7:
– print(), println()
– Loops: loop(), for, while, continue
– Conditionals: if/else, switch/case/default/break, ?:
– Relational & Logical Operators
– Creating PDFs. Tutorial link: http://www.processing.org/reference/libraries/pdf/index.html
– if there’s time, touching on Input and Output

  // draw the rect
  stroke(r, g, b);
  fill(r, g, b);
  rect(randomX, randomY, 20, 20);
}

int lastX = 200;  // last x value
int lastY = 200;  // last y value

void mousePressed() {
  // reset stroke to white
  stroke(255);

  // draw mouse line
  line(lastX, lastY, mouseX, mouseY);

  // save our last click point
  lastX = mouseX;
  lastY = mouseY;
