Draw an arc using Arcade in Python
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 moduleimport 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 colorarcade.set_background_color(arcade.color.WHITE)# Start the render process.arcade.start_render()# function for drawing arcarcade.draw_arc_filled(150, 144, 85, 86, arcade.color.BOTTLE_GREEN, 90, 360, 45, 54)# finished drawingarcade.finish_render()# to display everythingarcade.run() |
Output:
