Looking for more resources about ArrayLists

[debxyz]

I’ve been going through the code line for line. And I do understand almost all.

However, not clear to me is: boolean isDead, where there are 2 instances.

I noted next to the lines in question what I think is happening, but I am not sure this is correct.

The first instance in display():
I think this is a flow related question…

@Chrisir

void display() {
    if (isDead) //  boolean sets to TRUE at end of mousePressed event
      return; //  the oldCell isDEAD and does not display
    stroke(0);
    fill(col1);
    rect (x, y, 
      w, h);
  }//method

And second instance, in boolean onMouse:

@Chrisir

boolean onMouse() { 
    if (isDead) // ??? When TRUE return to FALSE state ???
      return false; // leave with false (mouse is never recognized on a dead cell)

    // this can return true or false: // I'm not sure what this means? Or why true or false is okay
    return 
      mouseX>x   &&
      mouseX<x+w &&
      mouseY>y   &&
      mouseY<y+w;
  }//method
