A student has coded this game and I cannot for the life of me figure out why the purple alien (player) stops moving after the score-triggered background change. Any help is appreciated!! > **[Check out what I made](https://studio.code.org/projects/gamelab/m0FHcj8Mp9R7IC86DXll2ymEzVzWvpZwE9GNnDC2Sg4)** > > I wrote the code myself with Code.org Thank you in advance! ---

In the function BGA2 your student is checking if score is higher than or equal to 30. If the score is higher than or equal to 30, the player’s x position will be set to 20. That’s why. Your student is running this every single frame, so its x position will be set to 20 every frame, without letting it move. ---

Of course! Thank you so much for your help!
