Step 6 of 12

Write settings.py

Open bobgame/settings.py and type this in

WIDTH = 800
HEIGHT = 600
FPS = 60
BG_COLOR = (30, 32, 38)

BOB_RADIUS = 20
BOB_SPEED = 250  # pixels per second
SKIN_COLOR = (233, 189, 150)
HAIR_COLOR = (70, 45, 25)
ARROW_COLOR = (240, 80, 60)

Each line is a variable: a name with a value stored in it, like a labelled box. We write the names in CAPITAL LETTERS because they are settings that never change while the game runs.

• WIDTH and HEIGHT are the size of the window in pixels (the tiny dots your screen is made of).
• FPS is frames per second. A game is like a flipbook, it draws a new picture many times a second. 60 looks smooth.
• Colours are three numbers: how much red, green and blue (0 to 255). (0, 0, 0) is black, (255, 255, 255) is white, and (30, 32, 38) is a dark grey-blue.
• BOB_SPEED is how many pixels Bob moves each second. The # starts a comment, a note for humans that Python ignores.

Try changing a colour later and see what happens. Pick colours with any "RGB colour picker" on the web.
