Draw a circle using Arcade in Python3

Last Updated : 22 Jul, 2021

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

Arcade inbuilt functions to draw circle :-

1. arcade.draw_circle_outline( ) : This function is used to draw the outline of a circle.

Syntax: arcade.draw_circle_outline(center_x, center_y, radius, color, border_width, num_segments)

Parameters:

center_x – x position that is the center of the circle.

center_y – y position that is the center of the circle.

radius – width of the circle.

color – color which with outline will be drawn.

border_width – Width of the circle outline in pixels.

num_segments – Higher is the number of segments, higher is the quality, but slower render time. The default value is -1 which means arcade will try to calculate a reasonable amount of segments based on the size of the circle.

Let’s take an example-

Python3

#import 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 background
arcade.set_background_color(arcade.color.WHITE)
 
# Start the render process.
arcade.start_render()
 
#function to draw a circle
arcade.draw_circle_outline(300, 285, 88, arcade.color.GREEN, 9,-1)
 
#finish drawing
arcade.finish_render()
 
#to display everything
arcade.run()

Output:

Since, now you know how to draw a simple outline of a circle. Let’s draw the Olympic flag using this arcade.draw_circle_outline( ).

Python3

#import 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 background color
arcade.set_background_color(arcade.color.WHITE)
 
# Start the render process.
arcade.start_render()
 
# function for designing olympic flag
arcade.draw_circle_outline(100, 285, 88, arcade.color.BLUE, 9, -1)
arcade.draw_circle_outline(300, 285, 88, arcade.color.BLACK, 9, -1)
arcade.draw_circle_outline(500, 285, 88, arcade.color.RED, 9, -1)
arcade.draw_circle_outline(200, 185, 88, arcade.color.YELLOW, 9, -1)
arcade.draw_circle_outline(400, 185, 88, arcade.color.GREEN, 9, -1)
 
# finished drawing
arcade.finish_render()
 
# to display everything
arcade.run()

Output:

2. arcade.draw_circle_filled( ) : This function is used to draw color filled circle .

Syntax: arcade.draw_circle_outline(center_x, center_y, radius, color, num_segments)

Parameters:

center_x – x position that is the center of the circle.

center_y – y position that is the center of the circle.

radius – width of the circle.

color – color which with outline will be drawn.

num_segments – Higher is the number of segments, higher is the quality, but slower render time. The default value is -1 which means arcade will try to calculate a reasonable amount of segments based on the size of the circle.

Let’s take an example-

Python3

#import module
import arcade
 
# Open the window. Set the window title and dimensions (width and height)
arcade.open_window(600, 600, "Draw  a circle  for GfG ")
 
# set background
arcade.set_background_color(arcade.color.WHITE)
 
# Start the render process.
arcade.start_render()
 
# draw circle
arcade.draw_circle_filled(300, 450, 78, arcade.color.PINK, 0)
 
 
# finish drawing
arcade.finish_render()
 
# to display everything
arcade.run()

Output:

Since, now you know how to draw a simple outline of a circle. Let’s draw a snowman using this arcade.draw_circle_filled( ).

Python3

#import module
import arcade
 
# Open the window. Set the window title and 
# dimensions (width and height)
arcade.open_window(600, 600, "Draw  a circle  for GfG ")
 
# set background
arcade.set_background_color(arcade.color.WHITE)
 
# Start the render process.
arcade.start_render()
 
# snowman upper part
arcade.draw_circle_filled(300, 450, 68, arcade.color.SKY_BLUE, 0)
 
# snowman eyes
arcade.draw_circle_filled(289, 475, 8, arcade.color.BLACK, 0)
arcade.draw_circle_filled(329, 475, 8, arcade.color.BLACK, 0)
 
# snowman lower part
arcade.draw_circle_filled(300, 350, 88, arcade.color.BLUE, 0)
arcade.draw_circle_filled(300, 250, 108, arcade.color.SKY_BLUE, 0)
 
# finish drawing
arcade.finish_render()
 
# to display everything
arcade.run()
