How do i fix this error? i am following the minecraft tutorial and wanted a menu but it says a variable isnt defined inside ursina code

[mavdotjs]

Ok, i checked https://github.com/pokepetter/ursina/blob/31cb718a1aac635ebc996e87f1ff3b688f793633/ursina/entity.py#L410 and i dont see any reference of a variable called 'render', was it meant to be a parameter?

[mavdotjs]

A snippet of my code:

quitbutton = Button(text='Quit', color=color.azure)
quitbutton.on_click = quit
wp = WindowPanel(
    title='Menu',
    content=(
        quitbutton,
        Slider(),
        Slider(),
        ),
        popup=True,
        enabled=False
    )
def input(key):
    if key == 'escape':
        wp.enabled = True

You need to create an instance of Ursina first.
