Here's a way to do it. Pretend you're trying to say, when ️ is double tapped, say "I Love You!"
When ️ Is Tapped:
Increase value <love> by 1
Whenever the ️ is tapped, it will increase this value by 1.
As you tap again, it'll increase the value to 2.
This is how it senses a double tap. It can also sense a triple tap.
How would you do this?
Well, once you tap it three times, the value love will equal 3. See how you can code this to sense anything?
When <love> = 2
Say, "I Love You!"
Wait # milliseconds
Set Value <love> to 0.
If you want this to keep sensing, you add a set value to 0 block again so you can start over the same process.
You're waiting because you don't want it to disappear right when love equals two.
Hope this helped!
