线条绘制（鼠标速度）

Posted 2021-02-25

Draw line on mousedown. Line width based on mouse movement.

void draw() {
  stroke(255);
  strokeWeight(abs(mouseX-pmouseX));
  if (mousePressed && mouseButton == RIGHT) {
    background(0);
    println (mouseButton);
  } else if (mousePressed && mouseButton == LEFT) {
    line(pmouseX,pmouseY,mouseX,mouseY);
  }
}
