我正在练习Arcade Library进行2D 游戏开发。但是我的第一个程序以错误告终！

我想用 Python 中易于学习的Arcade 库制作我的第一个 2D 游戏- 一个快乐的笑脸 -。

import arcade

# set constants for the screen size:
SCREEN_WIDTH = 600
SCREEN_HEIGHT = 600

# open the window, set screen size & dimension:
arcade.open_window(SCREEN_WIDTH, SCREEN_HEIGHT, "Hello, World! [Smiley]")

# set the bgcolor to white:
arcade.set_background_color(arcade.color.WHITE)

# start the render process, this must done before any drawing commands:
arcade.start_render()

# draw the face:
x, y, r = 300, 300, 200
arcade.draw_circle_filled(x, y, r, arcade.color.YELLOW)

# draw the right eye:
x = 370
y = 350
r = 20
arcade.draw_circle_filled(x, y, r, arcade.color.BLACK)

# draw the left eye:
x = 230
y = 350
r = 20
arcade.draw_circle_filled(x, y, r, arcade.color.BLACK)

# draw the smile:
x = 300
y = 280
width = 120
height = 100
start_angle = 190
end_angle = 350
arcade.draw_arc_outline(x, y, width, height, arcade.color.BLACK, start_angle, end_angle)

# finish drawing and display the result:
arcade.finish_render()

# keep the window open until the user hits the 'close' button:
arcade.run()

我期待一个“带微笑的黄色表情符号”。但我遇到了一个意外错误：

所以，我找到了。我没有专用显卡，并且我的内置英特尔显卡不支持抗锯齿。
