Are you saying you want help with the code?

It should be easy enough to use a variable to count the number of frames elapsed and to do something only if it is greater than 30; and just reset it to zero on mouseRelease, mousePress and mouseDragged.  Though you might find you want to allow slight movement and still invoke the drop method, in which case you could just store xy coords on mousePressed, calculate the distance from this each frame and reset to zero if it goes over a certain threshold...

I tested that and it has a slight bug:

If you just happen to move the cursor over the pmouseX and pmouseY position whilst dragging it switches state: perhaps not desired.  I had something like this in mind:

Code:

boolean mouseDown = false;
int frameCount = 0;
color bg_color = color(0);

void setup(){
  size(400, 400);
}

void draw(){

if(mouseDown) {  
  frameCount++;
}
  
    if(frameCount> 30){
      bg_color = color(255);
    } else {
      bg_color = color(0);
    }

  background(bg_color);
}

void mousePressed() {
  frameCount = 0;
  mouseDown = true;
}

void mouseDragged() {
  frameCount = 0;
}

void mouseReleased(){
  frameCount = 0;
  mouseDown = false;
} 

Note that this might not achieve what was intended either, since dragging switches the state back to 'off', perhaps not desired for a painting program where once a flow of drops has been established you might then want to allow the user to paint a stroke...

thanks guys! didn't know i could reset the frameRate(); it was a great help
