This was a fun activity. There were a couple of slides included in this activity. The first slide included two smaller books hidden behind a larger book. I was required to set up an automatic trigger with a delay, to have the two smaller books pop out from behind the larger book and land on a specific location. The second slide required me to set up a trigger on the left and right buttons, so as you click left button the box moves to the left, if you continue to click on the left button it continues to move to the left. The same goes if you press the right button, the box moves towards the right of the screen. This requires a Relative Start Point to be set on the left and right motion paths. Test them out then let me know how you got on.
