2021 Game Night Team
We are focusing on learning Python, OpenCV, Pygame, CNC and all the skills needed for us to take on the challenge of detecting skin cancer melanomas!
1/10/2021 Review progress so far
What did we learn?
What were the challenges?
How to apply to dermatology?
Review paper submission for Medical Image Analysis (here)
1/3/2021 Color Mapping and Identification
Focus on verifying colors for Candy Land
How to sample a bunch of cards
Determine color limits
Image below shows a bunch of sampled colors from the cards in Candyland. Notice that you could limit the range of colors to check if color is one color or another. For example look at the Blue min/max, Green min/max and Red min/max.
Could also determine the distance from the center of the color cubes

PyGame
The main website: https://www.pygame.org/news
The documentation page: https://www.pygame.org/docs/
We all install Pygame into PyCharm
What is PyGame good for?
Adding graphics
Adding sounds
Processing keyboard and mouse events
We learn:
How to initialize Pygame
Start the sound mixer
Add images
Play background music and sound effects
Process events including keyboard and mouse
Drawing with Pygame
Test, Lines, Circles, Rectangles
Colors
Example code below to draw a funny man
myColor = (255,70,30)
black = (0,0,0)
red = (255,0,0)
green = (0,255,0)
magenta = (255,0,255)
cyan = (0, 255,255)
yellow = (255, 255, 0)
white = (255,255,255)
blue = (0,0,255)
screen.fill(black)
pygame.draw.circle(screen, blue, (500,300), 250, 5)
pygame.draw.circle(screen, white, (500,300), 245)
pygame.draw.rect(screen, red, (300,170,150,20)) # x, y, w, h
pygame.draw.rect(screen, red, (550,170,150,20)) # x, y, w, h
eye1 = (400,230)
eye2 = (600,230)
pygame.draw.circle(screen, yellow, eye1, 55, 5)
pygame.draw.circle(screen, cyan, eye1, 50)
pygame.draw.circle(screen, yellow, eye2, 55, 5)
pygame.draw.circle(screen, cyan, eye2, 50)
pygame.draw.polygon(screen, yellow, ((500,225), (575, 345), (425, 345)))
pygame.draw.polygon(screen, magenta, ((500,225), (575, 345), (425, 345)), 5)
x, y = pygame.mouse.get_pos()
mouse = (x,y)
angle1 = mouseAngle(mouse, eye1)
eyeRadius = 28
pupil1 = (int(eye1[0]+eyeRadius*math.cos(angle1)), int(eye1[1]+eyeRadius*math.sin(angle1)))
pygame.draw.circle(screen, red, pupil1, 25)
angle2 = mouseAngle(mouse, eye2)
pupil2 = (int(eye2[0]+eyeRadius*math.cos(angle2)), int(eye2[1]+eyeRadius*math.sin(angle2)))
pygame.draw.circle(screen, red, pupil2, 25)

10/4/2020 - Discuss the Hot Pepper game
How do you win every time? That's the power of an algorithm
Discuss the algorithm for a game:
Initialization:
Who goes first?
Who are the players (are they computers/AI or real people)
Reset the board
Process the moves - Until and end is reached
Display the board
What moves are valid?
Have player pick a move (repeat until the move is valid)
Determine the new game state
Check if the end of the game been reached?
End of Game
Determine winner (or tie)
Display the results
Homework:
Pick a game
Think about the game algorithm
Continue your Python on-line lessons
Hot Pepper Game Rules:
There are 21 candies and one hot pepper
Each turn a player can pick 1, 2, 3, or 4 candies
Turns alternate until there are no candies left
Whomever picks the last candy must eat the hot pepper!
Objective: Not to be the one who picks the last candy
Is there a way to win every time if you go last?
Make your pick based on what the other person picks
Pick a quantity that makes the sum equal to 5
For example: Person picks 1, you pick 4
This will decrease the total from 21 to 16 to 11 to 6 to 1
