Object continuously jump upward when pressing a key
How can I set up a continuous upward movement for an object when a key is pressed, similar to the jump mechanic in Flappy Bird, where the object moves up as long as the key is held down?
Thanks! And how I add the gravity pulling down the object when the key is not pressed?
If all you need is up and down, then you could add a downward motion path to the object that plays on a timer which continually moves it down unless the key is pressed. You could make a timer in JavaScript or by creating and repeatededly showing a layer with a short timeline (maybe 0.25 to 0.5 sec) that triggers the downward movement (with a matching duration) on timeline end. You can also see the older post at Create a Timer for Storyline Any Version | Articulate - Community or try searching the forums for some ideas.
If also trying to move horizontally, I believe Storyline may play the motion paths sequentially, meaning one path will finish before the next begins, with leads to a choppy stair-stepped effect. I only did some brief testing. To get better and smooth results (like arcs), you may have to resort to JavaScript and GSAP to generate you movements.

For excellent results, you could also utilize a physics engine like matter.js to handle gravity and collision issues. For simple examples in SL, see

This would look great, but require a lot more work.
