如何修复体素游戏中的 python ursina 错误

Question

在我的 python 项目中，我有以下代码：代码抛出NameError: name 'render' is not defined

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

app = Ursina

class Voxel(Button):
    def __init__(self, position = (0,0,0)):
        super().__init__(
            parent = scene,
            position = position,
            model = 'cube',
            texture = 'white_cube',
            color = color.white,
            highlight_color = color.lime,
            origin_y = 0.5,
            scale = 0.5
            )

for z in range(8):
    for x in range(8):
        voxel = Voxel(position = (x,0,z))


player = FirstPersonController()

voxel = Voxel()

app.run

Answer 1

你忘了() 。

app = Ursina应该是app = Ursina() 。
