'ETCH' Drawing Demo

'Etch' Drawing experiment

This was a joint effort between me and Gemini

Gemini did about 70% of the code I provided the idea, as I was exprimenting with libraries. This really helped me understand how it worked

Use WASD to move the line and SPACE to shake it clean

            
import pygame
pygame.init()
screen = pygame.display.set_mode((600,600))

#pen position to start
x = 300
y = 300

white = (255, 255,255)
black = (0, 0, 0)



running = True

while running:

    for event in pygame.event.get():
        if event.type ==pygame.QUIT:
            running = False
        #if event.type == pygame.KEYDOWN:#is the key pressed?
    keys = pygame.key.get_pressed()

    if keys [pygame.K_w]:
        y-= 1 #Move up
    if keys [pygame.K_s]:
        y+= 1 #move down
    if keys [pygame.K_a]:
        x-= 1 #move left
    if keys [pygame.K_d]:
        x+= 1 #move right
    if keys[pygame.K_SPACE]:
        screen.fill(black)    
    # Keep X inside the left and right walls
    if x < 0:
        x = 0
    if x > 595: # 600 minus the 5-pixel width of your pen
        x = 595

    # Keep Y inside the top and bottom walls
    if y < 0:
        y = 0
    if y > 595:
        y = 595

    pygame.draw.rect(screen, white, (x, y, 5 ,5 ))

    pygame.display.flip()
