Arcade 内置函数在 Python3 中绘制多边形

街机库是一个高科技Python包，其中包含一组高级工具，可用于制作具有令人抓狂的图形和声音的 2D 游戏。它是面向对象的，专为Python 3.6 及以上版本构建。

Arcade 有两个用于绘制多边形的内置函数：

1. arcade.draw_polygon_outline( ) ：该函数用于绘制多边形的轮廓。

Syntax: arcade.draw_polygon_outline (point_list,  color,  line_width )

Parameters:

• point_list: List of points making up the lines. Each point is in a list. So it is a list of lists.
• color (Color): specify color using arcade.color.COLOR NAME. (Note that color name should in Capital letters.)
• line_width:- Width of the line in pixels.

例子：

Python3

import arcade
  
# Open the window. Set the window title and dimensions (width and height)
arcade.open_window(600, 600, "Draw  a polygon for GfG ")
  
arcade.set_background_color(arcade.color.ORANGE)
  
# Start the render process.
arcade.start_render()
  
point_list = ((30, 240),
              (45, 240),
              (60, 255),
              (60, 285),
              (45, 300),
              (30, 300))
arcade.draw_polygon_outline(point_list, arcade.color.SPANISH_VIOLET, 3)
  
arcade.finish_render()
  
arcade.run()

输出：

2. arcade.draw_polygon_filled( ): Arcade 的这个内置函数用于绘制填充有颜色的多边形。

Syntax: arcade.draw_polygon_filled (point_list, color )

Parameters:

• point_list- It is basically List of points where each point is in a list. So it is a list of lists.
• Color – specify color using arcade.color.COLOR NAME. (Note that color name should in Capital letters. )

# Start the render process.
arcade.start_render()
  
point_list = ((150, 240),
              (165, 240),
              (180, 255),
              (180, 285),
              (165, 300),
              (150, 300))
arcade.draw_polygon_filled(point_list, arcade.color.SPANISH_VIOLET)
  
arcade.finish_render()
  
arcade.run()
