I'm making a 3d game, in which a user can move vehicles using touch-controls that will allows the user to clear the parking area. this script is allied on the camera. this game this is like a 3D_Traffic_Jam_Parking clearance... I'm confused. I just tried to go on multiple learning platforms, but don't get it...!!!
