penDown()

Category: Turtle

Puts the pen down so the turtle draws a line behind it as it moves.

Just like you need to put the pen down on the paper to draw, the turtle pen needs to be put down to draw a line as it moves.

Examples

// Draw a line up from the turtle starting postion at the center of the screen.
penDown();
moveForward();

Example: Another Line Move the turtle from the center of the screen without drawing a line, then draw a line up.

// Move the turtle from the center of the screen without drawing a line, then draw a line up.
penUp();
moveForward();
penDown();
moveForward();

Example: X Marks the Spot Use penUp and penDown to have the turtle draw an 'X', returning the turtle to the starting point.

// Use penUp and penDown to have the turtle draw an 'X', returning the turtle to the starting point.
penUp();
move(-100,-100);
penDown();
move(200,200);
penUp();
move(-100,-100);
move(-100,100);
penDown();
move(200,-200);
penUp();
move(-100,100);

Syntax

penDown();

Parameters

penDown() does not take any parameters.

Returns

No return value. Modifies turtle drawing only.

Tips

penUp() is often used with penDown.
The default starting configuration for the turtle is with the pen down.
The color and width of the turtle line can be changed using penColor(color) and penWidth(width).
Turtle drawing commands are not effected by the show() and hide() commands, which control if the turtle icon is displayed or not.
If you are not seeing the turtle's movement, slow the program execution down by adjusting the tortoise/hare slider bar in the Debug Console or by using the speed() command.
