You cannot do it this way:

void ACharacter::Jump() {
	jumpingDelay = true;

}

You have to override the method in ACharachterMovement

virtual void Jump() override;

Then in cpp:

void ACharachterMovement::Jump() {
    Super::Jump();
	jumpingDelay = true;

}

Thanks, sorry for the late reply. A few months ago I had removed windows and replaced it with Ubuntu (ue4 isnt available on Linux :frowning: ). Yesterday I bought a second hard drive so now im able get windows too in dual boot mode so iā€™m finally able to use ue4 again. Although I lost the project I was working on , I have gotten better at cpp by a lot and your reply is very logical. Thank you SolidGasStudio!
