When either I use Player1 or Player2 whichever one I pressed R with first can cast this jutsu but Player2 cant if I pressed Player1 First I don't understand why it does this because when I press R on Player1 when I first join it shoots the jutsu but when Player2 presses R if he was not first then it would print my print statements but won't make the parts but if I use Player2 first it will please help me ?
