Python Arcade

Python Arcade

1. Prescribed and Self-Determined Criteria

   • Prescribed Criteria
     • Define and use a custom function to draw an element of your picture
       • Requirements
         • Illustrate stars of a constellation
         • Draw different patterns
         • Use variables like x and y for coordinates
     • Use multiple colours to enhance visual appeal
       • Requirements
         • Aboriginal colours such as warm tones including reds, yellows, etc must be used
         • Include cooler colours to represent constellations
         • Both CSS and Arcade colours to be used
     • Clearly reflect the selected theme (either Journey or Aboriginal Astronomy)
       • Requirements
         • Use shapes like lines and circles
         • Warm and cool tone colours used
         • Include patterns and significant symbols
   • Self Determined Criteria
     • At least one aspect of the design must be animated
       • Requirements
         • Constellation animated to shine brightly
         • Colour of animated objects must be modified
         • Must use a flickering effect to animate the stars
           • This was used instead of the standard way of animating in Arcade to simplify the code, as this is the only element to be animated

2. Coding Considerations

   • Code Samples
     • Draw a filled rectangle
       • arcade.draw_lrbt_rectangle_filled(0, 599, 0, 300, arcade.csscolor.GREEN)
     • Draw a filled circle
       • arcade.draw_circle_filled(100,450,50,arcade.csscolor.WHITE)
   • Packages
     • Arcade
       • drawing, animation, input
         • Used in image to draw shapes to represent objects and landscapes
     • playsound
       • playing audio files
     • pygame
       • 2D library, handles graphics
     • Random
       • used to generate random numbers within a range
         • Used in image to generate a random number between 0.8 and 1.2 for the width of the stars to animate them
   • Constraints
     • Must adhere to prescribed and self determined criteria
       • Should adhere to the requirements specified
     • Time limit
       • Draft copy due Wk7 Friday
     • Program must be written in Python
       • Arcade package must be used to create drawing
       • Thonny used for IDE

3. Python Drawing

   • Loops
     • Usage
       • To create multiple objects at different locations
       • To create gradient backgrounds
         • Purple coloured gradient used in sky
         • Orange gradient used in landscape
     • Example
       • "for i in range(200):", "arcade.draw_lrbt_rectangle_filled(0,600,0,600-i*3,(255,81+0.5*i,0+1*i))"
   • Example Shape Requirements
     • Circles
       • For creating aspects of the artwork including backgrounds
         • Used in the image to create the stars in the sky and as part of the constellation
     • Lines
       • For creating symbols and abstract designs
         • Used in the image to create the lines connecting the stars in the constellation

4. Challenge Details

   • Theme
     • NAIDOC Week Digital Artwork
       • Indigenous knowledge of the stars
         • Cultural storytelling
   • Background
     • Colour
       • Red, orange, black, white, etc
         • Warm Tone
           • Red, orange, yellow, black
             • Used to represent the Australian landscape in the image
         • Cool Tone
           • Purple, blue
             • Used in the sky section of the image
     • Pattern
       • Circles, lines, arcs
   • Research
     • Symbolism
       • Constellations linked to ancestral figures, animals, events from the Dreaming
   • Existing Artwork
     • Aboriginal Artwork
       • Aboriginal Astronomy Artwork
         • Includes key constellations and star patterns within Aboriginal culture
           • The Orion constellation, among others, is part of Indigenous culture and was featured in the image
