So I have a platform game I made in PyGame that all works, so I am now trying to make it a bit more colourful. So the code that I changed used to be:
def draw(self, screen):
""" Draw everything on this level. """
# Draw the background
screen.fill(BLUE)
and I changed it to:
def draw(self, screen):
""" Draw everything on this level. """
# Image from http://freepik
background_image = pygame.image.load("pink background.jpg").convert()
# Draw the background
screen.blit(background_image, [0, 0])
to get the pink background to be the background :) Now this is the only thing I changed in the code but everything now moves much slower e.g. the player that is being controlled by the user and the moving platform. There are two levels and I didn't change the code for the second levels background and the player still moves fine there :)
I did think I might of changed the line:
# Limit to 60 frames per second
clock.tick(60)
by accident, but it is still exactly the same.
I hope someone can help :) and thank you in advance :)
The error occurs somewhere in this code: `

Do not load the image in your main loop. Define (load) it outside of the loop and then use it via variable. This is your problem, because it loads the image (in this case FPS = 60) times per second from your disk.
