Difficulty Level : Expert
Last Updated : 20 Oct, 2020

The arcade library is a high-tech Python Package with an advanced set of tools for making 2D games with gripping graphics and sound. It is Object-oriented and is specially built for Python 3.6 and above versions.

Arcade has two inbuilt functions for drawing arc:

1: arcade.draw_arc_outline ( ): This function is used to draw an arc which is useful for drawing curved lines

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 .

Let’s see the below example:-

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()

Output:

2: arcade.draw_arc_filled( ): This function is used to draw a arc filled with color which are useful for drawing pie-wedges, or Pac-Man.

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.

Let’s take an example to get a clear picture of the functionality.

Python3

# 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()
