Hi! So confused. I am making a typical ball bouncing game, (bounce from trampoline to basket with line) anyway, my bouncer is just a thick line. It does not show unless there is another line in the program, but if I make that line smaller than the first line and put it inside the first line, it disapears again, until I move it up enough to show, and then the whole thing shows. I am super confused. Please help!
