Turtle state values (can plug into a parameter):

* X, Y~~, Heading (~~Zeros for each are center screen, pointed up. Heading is degrees clockwise.)

* X, Y – Zeros for each are at center screen. Negative values are left and down; positive values are right and up.

* ~~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).

* Heading – Zero is pointed up. Heading is in degrees clockwise.

::~~Example~~: 90 means a right angle clockwise, –30 means a 30 degree angle counterclockwise

* 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
