I've been working on a little side project while making my first Pico-8 game.
It's a cart with some art in it.
I've recently tried adding in a zoom feature for the smaller art.
But for some reason it won't change screens.
Any help would be great.
My best guess (didn't look super closely):
Your big if-elseif block in _update() is never going to check for mode==1 or anything after that because one of the first two conditions of the if-elseif is always going to be true - either screen will be 0 or greater than 0. As soon as it hits one that matches, it will skip the rest. You probably want to put all the elseif mode==1, 2, etc INSIDE the elseif checking for screen > 0.
You also have a problem in update_zoom(), unrelated but will probably bite you eventually. When you are in the zoom screen and press the circle button to go back, you set mode to 0. Then at the end, you do a check for mode < 1 and reset it to 9, so it will never be 0 when the function ends and as a result, you will never go back to the update_main() function.
Thanks! It changes the screen now. Somehow missed that whole if-elseif thing.
Also thanks for the extra tip.
