When i want to make a platformer and I choose the ground the be the line it doesn't show. I make the sprite, draw a line, make it go to front layer, make it show and make it go to x: 0, y: 0 it still doesn't show. I tried making a sprite then putting some random drawing, making a line and deleting the random drawing, byt that didn't work as well. As soon as i deleted the random drawing the line disappeared.
