STEP 7: Time to make our car obstacles! The cars will appear and move across the stage infinitely.
An Interval Event repeats an action infinitely and we can set the frequency -- how often the event happens!
- From the toolkit, drag out Interval Event to the bottom of the program.
- Change the frequency of the interval on this line: stage.event_interval(interval,·2) Change 2 to 0.5!
- Click Run to see what happens! What action repeats infinitely? We'll change the action in the next activities.
