How do I make it so a single button press jumps, while double-tapping switches sides?

So i'm currently working on a vertical platformer where you have to make it as far as possible by jumping to opposite walls. I want to make it so that if I tap spacebar, then the player jumps and lands shortly after on the same wall, but double tapping it makes it so you switch to the opposite wall. No clue how to do it, so i'm asking for help. Thanks in advance!

You have to create your own double tap event using Timer behavior. It can look like this:

Be aware that there will always be a little delay when pressing the button only once. You need a small time window to check if the button is pressed again.

Hey WackyToaster! Your example looks better if thats the way the object should move. In case the object moves in different directions (for example Tap > move left, Doubletap > move right) you have to check before moving otherwise one direction would be taken and changed shortly thereafter.
