Hi there. I did a small experiment with the dash system. I already managed to made the dash system code in the FirstShooterCharacter.cpp and the header file. It works fine but I want to make our character only dash when they are moving. Here is my FirstShooterCharacter.cpp and the header file. Any helps will be fully appreciated. Cheers.
