Example "Arcade" library code.
|
|
|
|
This example shows the drawing primitives and how they are used.
|
|
It does not assume the programmer knows how to define functions or classes
|
|
yet.
|
|
|
|
API documentation for the draw commands can be found here:
|
|
http://arcade.academy/quick_index.html#id1
|
|
|
|
A video explaining this example can be found here:
|
|
https://vimeo.com/167158158
|
|
|
|
If Python and Arcade are installed, this example can be run from the command line with:
|
|
python -m arcade.examples.drawing_primitives
