Guys, this is my soccer system. I have a problem, I'm trying to make when the player presses lshift he kicks the ball and the ball goes ahead of him, I tried a matrix code that I found here in the forum(line 39 at 43), but I could not make it work as I wanted it to work be! can you help me? if I was not clear sorry! and any English error forgive me I'm Brazilian.
