Not sure why everything disappeared

UPDATE:: I have a button in this code that lets the user pick the song but I can’t get it to show up, not sure why any suggestions?

@charmypatel it’s in the top left?

No not that button, there is another button in the center of the moon (if you click in the black space in the middle) you cant see it but its there. I’m trying to get that button to the top left corner like the purple one is in the picture you posted.

@charmypatel ah I think what’s wrong,

  rect(buttonX, buttonY, buttonW, buttonH);

is the button you mean? this is a wider rect in the center of the screen, but it gets drawn BEFORE the colored ellipse, which will then be drawn on top of the button, making it invisible.
moving those two lines of code to the bottom of draw() fixes this, though you may need to fix the coloring as I’m not sure if that is still correct.

Thank you so much! I was able to get the button to show up after moving the code like you mentioned.
