Let’s say you’re
building a Desmos activity that has
some kind of animation in a graph. Maybe points going around the unit circle,
or objects being launched in some kind of trajectory. Maybe you want a point
to trace out a line.
Whatever it is, the Friday Fave recommends you use an Action Button to get things started.
First get your graph set up on your Activity Builder screen, using a slider to animate your thing. You can call that slider whatever you like, but T is nice because T stands for time (and while you can use lower-case t, it’s wise to reserve that for any parametric curves you might end up drawing).
Now put an Action Button on that screen, and give it a name.
Then head over the graph script and put that button to work.
The Fave used 6.28 in the parentheses so that the animation would last about 2 pi seconds. You can put anything you want there. Leave it blank for a default of 10 seconds.
Action Buttons. So simple; so useful. That makes them this week’s Friday Fave. And here are four activities that use Action Buttons to make a bunch of different things happen. Now that you have Computation Layer turned on, you can copy and edit them to see how those buttons work.
