Have two animations that fly in from the left and would like one to 'hop' across the screen and then the other going back and forth. Yes I said hop. I"m putting together a short PPT for my grandkids and have an animated hopping bunny flying in from left to right of screen.
I have one at the bottom of the screen and the other near the top.
Trying to figure out how to make one hop across the screen, disappear and then the other does the same and then repeat 4-5 times or until we stop presentation..
I can get them to hop across screen, disappear and then the other one does the same. Just can't repeat. If I use 'repeat' then the first one hops across screen 4-5 times then the other so I don't think that will work.
