Arcade

Arcade is a library that we will need to import to the top of every program we write from this point on. It helps us draw pictures and build games!

SLIDE 3

#1: Import Arcade

1 2 3 4 5 6 7 """ This is a sample program to show how to draw using the Python programming language and the Arcade library. """ # Import the "arcade" library import arcade

The import statement must always be the very first line of code at the top of every program (excluding comments)

#2: Open Window

Did you see that?

Activity 1: drawing_shapes.py

Once you’ve run drawing_shapes.py, change around whatever elements of the shapes you want, including:

What text displays when the window opens
The background color of the window
The parameters of each draw function:

○ Width and height of shapes ○ Color of shapes ○ Alpha value of the shapes ○ Angle of the shapes

Activity 2: drawing_picture.py

See your course website for instructions, which are under Session 2. Also see “Hints/Notes” for more information. Use your sketches from last session!

SLIDE 15

Now...what will we draw? Pull out last week’s sketches and use them as a guide!
