一筆到底

 void setup() {

  size(600, 400);
}
void draw() {
  if (mousePressed) {
    line(pmouseX, pmouseY, mouseX, mouseY);
  }
}

stroke改顏色

void setup() {
  size(600, 400);
}
void draw() {
  stroke(#20744F);
  if (mousePressed) {
    line(pmouseX, pmouseY, mouseX, mouseY);
  }
}

key 換顏色

void setup() {
  size(600, 400);
}
void draw() {

  if (key=='1')stroke(#20744F);
  if (key=='2')stroke(#15C5E3);

}
