translation of the AP CSP Reference Sheet (July 2015 edition).
Version 2016-05-10.Assignment, Display, and InputArithmetic Operators and Numeric ProceduresRelational and Boolean OperatorsSelectionIterationList OperationsProcedures are defined with the "make a block..." context menu. Right-click (on Macs control-click) on the Scripts background to get to it. There's also a "Make a block" button in the Variables tab. Procedures that return values should be a "Reporter" (or "Predicate").
Procedures that don't return values should be a "Command".Robot
Note that you can make your own mazes interactively! Click on the grid to toggle cell states between empty [white], goal [grey] and blocked [black]. You can also use the arrow keys to move the robot around, and down arrow says the status of CAN_MOVE around.
You can also convert a maze into a text description of it, allowing you to edit the maze offline, and load/save that way. MAZES is a global variable that has a few mazes stored this way we use in the demo.END OF SNAP! CODE TO MIRROR THE REFERENCE SHEET...These are "hat blocks" that let you move the robot around, test CAN_MOVE when you click on the four arrow keys, and respond when you interactively click on the grid.General-purpose robot helper functions.This sets things in motion when the project starts, with a nice message displayed and then demos the maze-solving algorithm.What follows are Course and Exam Description sample coding questions"***************
