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')
