Python Ursina 隐藏 UI

Question

我有一个 GUI 物品栏，但我不知道如何隐藏它以及里面的所有物品。我试图使 class Inventory(Entity) 启用或不启用，但它没有用，因为它只启用而从未禁用。这是我的第一个 post 所以，请保持友善。

我的代码：

from ursina import *
from ursina.prefabs.first_person_controller import FirstPersonController


app = Ursina()

class Inventory(Entity):
    def __init__(self):
        player.enabled = False
        super().__init__(
            parent = camera.ui,
            model = 'quad',
            scale = (.5, .8),
            origin = (-.5, .5),
            position = (-.3,.4),
            texture = 'white_cube',
            texture_scale = (5,8),
            color = color.dark_gray
            )

        self.item_parent = Entity(parent=self, scale=(1/5,1/8))
        enable = False


def input(key):

        if key == 'f':
            inventory_enable()


            
def inventory_enable():

    inventory = Inventory()
    Inventory().enable = False
    ...

Answer 1

设置entity.enabled = False 将停用它及其所有子项。要使其重新出现，请将其设置回 True。
