Looping in the Coding Environment
Looping in the Coding Environment
Summary:
As a learner, I would like to create programs in the Inclusive Coding Environment that allow me to repeat sequences.
Details:
- 'Loop' is available in the Actions Panel
- Add a Loop feature
- Inserts start loop, end loop, loop counter and the ability to add contents to the loop
- The loop may specify a fixed count of iterations, or "forever"
- The loop is executed the number of time specified in the loop counter
- The loop is highlighted and counts down to 0 during execution
- The control panel for the 'Start Loop' and 'End Loop' tiles have the following operations:
- Move Loop
- Contents of the loop move with it (see below for an example)
- Delete Loop
- Dialog to determine whether the contents of the loop are also deleted
- Move Loop
- Loops may be nested
Notes and Examples:
Movement of Loops
When a loop is selected to be moved, the entire loop moves as if it is a single tile. It will move in or out of an enclosing loop when directed to.
start-loop-a, forward, end-loop-a, start-loop-b, end-loop-b
Move start-loop-a next
start-loop-b, start-loop-a, forward, end-loop-a, end-loop-b
Move start-loop-a next
start-loop-b, end-loop-b, start-loop-a, forward, end-loop-a
Movement of tiles in relation to loops
start-loop-a, forward, end-loop-a, start-loop-b, end-loop-b
Move forward next
start-loop-a, end-loop-a, forward, start-loop-b, end-loop-b
Move forward next
start-loop-a, end-loop-a, start-loop-b, forward, end-loop-b
Loop Counter
- Maximum number of loop iterations is 3 digits: 0 - 999
- Default is 1
- If the counter is empty, treat it as 0
- Counter only allows digits to be entered
- Loop counts cannot be changed while a program is running
- During execution, counter remains at 0 after the loop has completed and resets to the original value when the program stops
- The loop counter ‘Stop’ button breaks out of the loop and continues after the loop (maybe it should be “escape”?)
