My code for a game that I’m creating is has a jump logic. But in playmode my jump is going backwards instead of just going straight into the Y axis. I don’t understand why. Every time I jump my character goes backwards while in the air jumping and lands backwards of his original position. sorry for bad english. This is my code please help and ignore the comments please they are in portuguese!
