Turtle state values (can plug into a parameter)
Turtle state values (can plug into a parameter):
* X, Y, Heading (Zeros for each are center screen, pointed up. Heading is 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).
::Example: 90 means a right angle clockwise, –30 means a 30 degree angle counterclockwise
