Let's look at a portion of your main loop:
while True:
hero.draw()
keysPressed = pygame.key.get_pressed()
if keysPressed[K_a]:
hero.x = hero.x - 3
if keysPressed[K_d]:
hero.x = hero.x + 3
if keysPressed[K_w]:
hero.y = hero.y - 3
if keysPressed[K_s]:
hero.y = hero.y + 3
screen.fill((0, 255, 0))
Inside the Hero class's draw function, you are drawing the rect. In the main loop, you are calling hero.draw()
, and then after handling your inputs, you are calling screen.fill()
. This is drawing over the rect you just drew. Try this:
while True:
screen.fill((0, 255, 0))
hero.draw()
keysPressed = pygame.key.get_pressed()
....
That will color the entire screen green, then draw your rect over the green screen.
