List of available commands

There is a predefined turtle object t. Therefore, all commands start with t, like t.fd(100);

  • t.forward(len); or t.fd(len);
  • t.back(len); or t.bk(len);
  • t.right(angle); or t.rt(angle); ([math]\displaystyle{ 0\leq angle \leq 360 }[/math])
  • t.left(angle); or t.lt(angle);
  • t.penUp(); or t.pu();
  • t.penDown(); or t.pd();
  • t.clearScreen(); or t.cs();
  • t.clean();
  • t.setPos(x,y);
  • t.home();
  • t.hideTurtle(); or t.ht();
  • t.showTurtle(); or t.st();
  • t.setPenSize(size); (size: number)
  • t.setPenColor(col); (col: colorString, e.g. 'red' or '#ff0000')
