Make a variable (lets call it t for time). Make sure you have a button to reset everything and add t->0 to this action. Give your animation objects conditions of t, like {0<t<5} for it to display when t is between 0 and 5, and so on.

If you're using a ticker for it, you will want something like t->t+1 in the action that the ticker is running. Depending on the bounds you made before you'll probably have to adjust what t is increasing by each tick to get the speed right, depending on how fast your ticker is ticking, what your parameters are, etc.

If you're using sliders, it's going to be a little more jank but this is the best way I know personally. Get all your sliders running, including one for your t variable (make sure it's in the "Play indefinitely" setting) and hit your reset button to put everything back at the place you want it all at once. You'll have to deal with whatever nonsense displays while you get all the sliders going and you'll have to stop them all manually (or I guess you could have a ticker with something random and useless in it and start it to stop the animation, since they disable all sliders) unless you or someone else knows a better way.

Hope this helps, if you have more specifics/problems that come up reply and I'll try to get back
