  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

this code works for vertical collisions but breaks when moving on platforms horizontally. how can i fix it

How does it break?

when on the platform, i can stand on top of it without moving but once i move left and right it teleports me to the side of the platform

I'm unfamiliar with pygame and game development in Python, in general, but I did notice these lines:

for platform_rect in platform_rects:
                    #checks for collision of any platform in the list
                    if player_rect.colliderect(platform_rect):
                        if total_movement[0] > 0:
                            self.pos[0] = platform_rect.left - self.size[0]
                            self.velocity[0] = 0
                        if total_movement[0] < 0:
                            self.pos[0] = platform_rect.right
                            self.velocity[0] = 0

Logic like on line 56 seems to just set the position to the left side of the platform whenever any collision is detected (which would be detected since you start by standing on the platform) and the speed of the player is greater than zero.

#

It seems like you need a more granular collision detection to differentiate between the player touching the sides of a platform versus the top or bottom of it.
