How to make my character jump once on hold key

How to make my character stop jumping non stop when i hold the up arrow.

I read there is option Allow buny hoping, but cant find it.

You could use variables:

An instance variable on the character called "Jump" for example

If Jump = 1

Up arrow down

----->Jump character

----->Set variable Jump to 0

If Up arrow released -----> Jump = 1

Sorry but i cant follow, im new to the program and im not good with variables and avents.

I just tested the Platform behaviour and by default the character won't jump again until I release and press the up arrow a second time.

What is happening for you and what behaviours are you using? If you like, post the capx file (you can freely host it using dropbox.com/).
