 | Forward (number) | move turtle forward |
 | Back (number) | move turtle backward |
 | Left (angle in degrees) | turn turtle counterclockwise |
 | Right (angle in degrees) | turn turtle clockwise |
 | Arc (angle in degrees,radius) | move turtle along an arc |
 | Setyx (xcor, ycor) | move turtle to position (xcor, ycor) [(0, 0) is in the center of the screen.] |
 | Seth (heading) | set the heading of the turtle [0 is towards the top of the screen.] |
 | Show (media) | draw text, images, or play sounds |
 | Set scale (media) | Set the scale of images |
 | Container | Load a media object from the Journal (plugs into the Show block) |
 | X coordinate | holds current x-coordinate value of the turtle (can be used in place of a number block) |
 | Y coordinate | holds current y-coordinate value of the turtle (can be used in place of a number block) |
 | Heading | holds current heading value of the turtle (can be used in place of a number block) |
 | Scale | holds current scale value |
Turtle state values (can plug into a parameter):
- X, Y – Zeros for each are at center screen. Negative values are left and down; positive values are right and up.
- Heading – Zero is pointed up. Heading is in degrees clockwise.
- Angles are degrees from 0 to 360 (for larger values and smaller values all multiples of 360 are subtracted or added to get the value into the range 0..360).
- Examples: 90 means a right angle (90 degrees), clockwise; –30 means a 30-degree angle, counterclockwise
