I tried to do everything the way you said. I mentioned which ones I used in the photo with colors. Currently, when I press the q key in the game, the paper is opened, but it remains constant and does not go in any way. I also added a photo of the error.
There is something on my mind. When we pressed the Q key, we added all the widgets to be read, but we used only the widget of 1 paper in the code, which is “WP_Not”, which represents only one paper.
