Im sorry I replied so late,i took a little break for the holidays.I have read what you said and I have done that,and its successful,i can use inputs now :D. Now all I need to do is to figure out the random AI movement again(because it stopped working after i set the controller up) and I will be all set (i dont know if i should make the movement in the controller or the ball_BP).All in all thank you for helping me,thanks to you i have learned many things and im very grateful!The picture is of my current AI random movement,it was in my ball_BP but i have moved it to controller for some test.
