Depending on what you want to do @glv’s method can be better I think.

The issue with mine is that you need to store the position of all the points. I limited the number of points created with the minDist variable but still, if you run it long enough, you might have a really long array of point and it might start running slow over time. It will depend on the hardware and the use case.

Okay. I’ll play with both codes for a bit to find out which one fits my use.

Hello,

I added this to draw to display number of points and frameRate every 10 frames:

  if (frameCount%10 == 0)
  surface.setTitle(str(pts.size()) + "  " + str(frameRate));

It does indeed slow down after a while; I noticed dropping after 600 points here.

:)

I tried for fun: lost 1 FPS after 3500 points.

ah i see you treat lines like image and change transparancy with tint() this my code:

PGraphics pg;

void setup() 
{
  size(640, 480);
  pg = createGraphics(width, height);

  textSize(130);
  textAlign(CENTER, CENTER);
}

void draw() 
{
  background(200);   
  text("TOP", width/2, height/3);

  pg.beginDraw();
  pg.line(pmouseX, pmouseY, mouseX, mouseY);
  pg.strokeWeight(5);
  pg.stroke(255,0,255);
  pg.endDraw();
  
  tint(255, 0, 255, 50);
  image(pg, 0, 0); 

  text("BOT", width/2, 2*height/3);
}
