So I have some screens working in my game. When I click on a menu item, it highlights to show it's selected. But I found that the menu items stay highlighted even after leaving the menu.

Here's a video to show what I mean.

Here's the code for the move menu (The menu used in the video.)

Code: Select all

screen move_menu():
    tag act0
    default selected_item = None
    default selected_location = None
    add "ui/menu_list.png" at fastFade:
        pos (1089, 354)
    fixed at fastFade:
        xysize (416, 426)
        pos (1101, 366)
        vpgrid:#vbox:
            cols 1
            spacing -4
            draggable True
            mousewheel True
            scrollbars "vertical"
            xpos 0 #147
            ypos 0 #57
            side_xalign 0.0
            for location_item in location_list:
                textbutton location_item.name xysize (401, 50):
                    bottom_margin 10
                    right_margin 5
                    left_padding 10 #25
                    text_size 25
                    text_color "fff"
                    background "#222"
                    hover_background "#f00"
                    selected_background "#960000"
                    action (SetVariable("selected_location", location_item.name)), (SetScreenVariable("selected_item", location_item))

    fixed at fastFade:
        xysize (391,230) #(369, 208)
        xpos 1530 #1538
        ypos 355 #366
        if selected_item:
            add "inv_bg":
                yalign 0.5 xalign 0.5
            add selected_item.pic:
                yalign 0.5 xalign 0.5

    fixed at fastFade:
        # xysize (273, 175)
        xpos 1530
        ypos 587
        if selected_item:
            frame:
                textbutton "Go" action Hide("move_menu"), Hide("action_menu"), Jump("location_manager")
        else:
            null
        # text "Go"

    imagebutton pos (1240, 823) at fastFade:
        idle "ui/travel_button.png" hover "ui/travel_button.png" action Hide("move_menu")

I want the option to stop being highlighted after leaving the menu.
I appreciate any suggestions.

First, you should understand, how button deterrmines if it is selected or not. First of all it looks for selected property. If provided, button will be selected if it evaluates to True and deselected otherwise. If selected property is not provided, it looks at the actions to determine if button is selected. I do not remember which action is selected if list of actions is provided, but for Set*Variable family of action button is considered selected if variable is already assigned desired value. In your case, for example, it will be selected if variable selected_location equals to location_item.name

TL;DR: reset your variable to None each time the screen is shown.

Isn't that what the following does?

Code: Select all

    default selected_item = None
    default selected_location = None

Or is there another screen function I'm not finding?

I do not remember in which cases it reset variables, but at least this SetVariable("selected_location", location_item.name) sets global variable (or, rather, store variable) and not screen variable, so it is not affected by default statement.
