Exercise Tracker

Resetting

If you’re anything like me, you might want a way of deleting all the previously entered data and starting the tracking again at zero. Let’s add a button to let you do that!

  • In the Designer view, add a Button. Change its label to Reset.

  • Go to Blocks and add a when Button Click block for the new button.

  • Into this block, add call File1.Delete with a Text block giving the file name ExerciseTracker.txt.

Now you will create a brand-new block of your own!

  • Click on Procedures in the Built-in blocks and drag out a to procedure do block.

  • Click the procedure label and change it to resetEverything.

What is a procedure?

A procedure is a bunch of code that you can reuse easily.

Instead of duplicating the same blocks in several places, you put all of them into one block called a procedure. Then you can use just that one block whenever you want to run these blocks!

You can give a procedure any name you want.

  • Inside the resetEverything block, add blocks to set the global minutesList to a new empty list, set the global totalTime to 0, and display the new total:

  • Finally, in the when Button Click block of the button you’ve just made, add the block call resetEverything from Procedures.

Now you should be able to clear all the recorded exercise by clicking the new button!
