在Python中使用 Arcade 绘制圆弧

街机库是一个高科技Python包，其中包含一组先进的工具，用于制作具有抓人眼球的图形和声音的 2D 游戏。它是面向对象的，专为Python 3.6 及以上版本构建。

Arcade 有两个用于绘制圆弧的内置函数：

1：arcade.draw_arc_outline()：这个函数用来画一个圆弧，对画曲线很有用

Syntax: arcade.draw_arc_outline(center_x , center_y, width , height, color, start_angle, end_angle , border_width, tilt_angle, num_segments)

Parameters:

• center_x : x position that is the center of the arc.
• center_y : y position that is the center of the arc.
• width : width of the arc.
• height : height of the arc.
• color : Outline color of the arc.
• start_angle : start angle of the arc in degrees.
• end_angle : end angle of the arc in degrees.
• border_width : width of line in pixels.
• tilt_angle : angle the arc is tilted.
• num_segments :  Higher is the num of segments ,better is the quality .

让我们看看下面的例子：-

Python3

import arcade
  
# Open the window. Set the window title and
# dimensions (width and height)
arcade.open_window(600, 600, "Draw  an arc  for GfG ")
  
arcade.set_background_color(arcade.color.WHITE)
  
# Start the render process.
arcade.start_render()
  
arcade.draw_arc_outline(150, 81, 15, 36,
                        arcade.color.BLACK, 90, 360)
  
arcade.finish_render()
  
arcade.run()

输出：

2： arcade.draw_arc_filled()：这个函数用来绘制一个填充有颜色的圆弧，这对于绘制楔形或吃豆人很有用。

Syntax: arcade.draw_arc_outline(center_x , center_y, width , height, color, start_angle, end_angle , tilt_angle, num_segments)

Parameters:

• center_x : x position that is the center of the arc.
• center_y : y position that is the center of the arc.
• width : width of the arc.
• height : height of the arc.
• color  : color to be filled in the arc.
• start_angle : start angle of the arc in degrees.
• end_angle : end angle of the arc in degrees.
• tilt_angle : angle the arc is tilted.
• num_segments : Number of line segments used to draw the arc.

让我们举一个例子来清楚地了解功能。

蟒蛇3

# import arcade module
import arcade
  
# Open the window. Set the window title and
# dimensions (width and height)
arcade.open_window(600, 600, "Draw  an arc  for GfG ")
  
# set a background color
arcade.set_background_color(arcade.color.WHITE)
  
# Start the render process.
arcade.start_render()
  
# function for drawing arc
arcade.draw_arc_filled(150, 144, 85, 86,
                       arcade.color.BOTTLE_GREEN, 90, 360, 45, 54)
  
# finished drawing
arcade.finish_render()
  
# to diaplay everything
arcade.run()

输出：
