判断当前菜单页面的方法

apoto5

UI设计需要判定当前处在哪个界面，显示相应的按钮，请问对于自定义的菜单screen应该如何判断状态呢？

[RenPy] 纯文本查看 复制代码

screen evidence():
    tag menu
    predict False
    use game_menu(_("证物"), scroll="viewport"):


        style_prefix "evidence"
use navigation

[RenPy] 纯文本查看 复制代码

screen navigation():
    if evidence:
        image"evidence_main.png"
    else:
        imagebutton:# evidence
            idle "gui/setting/evidence.png"
            hover "gui/setting/evidence_hover.png"
            xpos 869 ypos 17
            action ShowMenu("evidence")
