output stills using keyPress and saveFrame functions

osyrus11

Hi all, I'm a complete beginner trying to get into it. This is my first little doodle. I'd like to be able to hit "enter" in order to export the current frame into a folder in the sketch folder (script folder) and I've hit my first brick wall. What have I done wrong here. Can anyone explain to me what I'm failing to grasp?

the } of the function draw() must close after the ellipse() command

void setup() { 
  size(600, 600); 
  background(160); 
  frameRate(24);
  smooth();
}

void draw() { 
  ellipse(mouseX, mouseY, 80, 20);
}

void keyPressed() { 
  if (keyCode==ENTER) { 
    saveFrame("screen-####.jpg");
  }
}

thanks!

but also, I thought the keypress function had to be coded into "draw"s function block?

Java language doesn't allow functions inside another function. :-B
Although it does allow classes & interfaces inside another class or function! ;)

Alright that clears things up for now. Rule-Keep my functions separate from each other. As for class/interfaces not sure what that means in this particular scenario, butthat's some higher level stuff I'll have to research, in the meantime thank you for your help!.

Just mentioned those for completeness' sake! L-)
