Note: The following can be used to stop an object from leaving canvas

Getting too big? / Going too far right? - Positive values

Step 1: Create a speed variable in initialize(). The number should be the same as whatever you are adding/subtracting in your update line.

If you have in repeatingForever():

Then in initialize(), you should add:

Step 2: In repeatingForever(), change your "update" line so that it uses the speed variable you created.

becomes...

Step 3: In repeatingForever(), add an if-statement and set q1speed to 0.

• Always use ">" to stop the shape from getting "too big."
• The number to "stop" at shouldbe bigger than the one in initialize().

Here's how the code looks like now:
