turnRight(angle)

Category: Turtle

Rotates the turtle right by the specified angle. The turtle’s position remains the same.

turnRight() is one of the ways to change the turtle's orientation. When used with moveForward(), you can move, and draw with, the turtle anywhere on the screen.

Examples

// Rotate the turtle right 90 degrees (the default angle) from the current direction.
turnRight();

Example: Step Draw a step with a right turn and a left turn.

// Draw a step with a right turn and a left turn.
moveForward();
turnRight();
moveForward();
turnLeft();

Example: Letter W Draw the letter W with right turns only.

// Draw the letter W with right turns only.
turnRight(150);
moveForward();
turnRight(-120);
moveForward();
turnRight(120);
moveForward();
turnRight(-120);
moveForward();

Example: Star Draw a 25 pointed star by first calculating the exterior angle turn necessary.

// Draw a 25 pointed star by first calculating the exterior angle turn necessary. 
var points = 25;
var exteriorAngle = 180.0 - (180.0 / points);
for (var i = 0; i < points; i++) {
  moveForward(200);
  turnRight(exteriorAngle);
}

Syntax

turnRight(angle);

Parameters

Name	Type	Required?	Description
angle	number	No	The angle to rotate right (90 degrees is default).

Returns

No return value. Rotates turtle only.

Tips

You can specify a negative angle to turn right, which makes the turtle turn left instead.
There are three ways to rotate the turtle in place
- turnRight(angle) - Rotates the turtle right by the specified angle relative to the current turtle direction. The turtle’s position remains the same.
- turnLeft(angle) - Rotates the turtle left by the specified angle relative to the current turtle direction. The turtle’s position remains the same.
- turnTo(angle) - Rotates the turtle to a specific angle. 0 is up, 90 is right, 180 is down, and 270 is left. The turtle’s position remains the same.
