I’m using this code to jump and double jump with my character:
However, if I continue to press my Jump button on landing, the character don’t loop the jump. Is there a way to continue jumping if the Jump key is continued to be held on landing?
Are you using the ThirdPersonCharacter template? If so, you might want to look into the actors details.
There should be a jump max count setting. I never tried it myself, but I imagine it could spare you some headache.

Yes, I set Hold time to 0,01 and Max Count to 2 so he can do the double jump.
Then maybe this helps:

Since the button only fires a single time when it’s pressed, you probably need to go for a while loop to continue performing the action you want.
I have done something similar but forgot about the delay, it’s working now, thanks 
Yeah I was wondering why it didn’t work without delay. I came across this couple times already in various scripts. At the end it worked.
Glad I was able to help.
