I was following this guys tutorial on how to make an object rotate around another, as I wanted to make a sword rotate around the player and follow the mouse. On his machine the code works great and is exactly what I want to achieve, but on my machine it starts to consume a ton of RAM extremely fast and crashes the program.

class Sword():

def __init__(self, pivot:Vector2):

    self.pivot = Vector2(pivot)
    self.pos = pivot + Vector2(20, 0)
    self.image_original = sword_1
    self.image = self.image_original
    self.rect = self.image.get_rect()

def update(self):

    mouse_pos = Vector2(pygame.mouse.get_pos())
    mouse_offset = mouse_pos - self.pivot
    mouse_angle = -math.degrees(math.atan2(mouse_offset.y, mouse_offset.x))

    self.image, self.rect = rotate_on_pivot(self.image, mouse_angle, self.pivot, self.pos)

def draw(self):
    screen.blit(self.image, self.rect)

sword = Sword((character.x_pos, character.y_pos))

This is the code for creating the sword, updating its position based on the mouse, and then drawing it. There is also another function for rotating it around a pivot point.

def rotate_on_pivot(image, angle, pivot, origin):

surf = pygame.transform.rotate(image, angle)

offset = pivot + (origin - pivot)
rect = surf.get_rect(center = offset)

return surf, rect

I’ve found out that the issues begin when I call the update method. This happens even without using the draw method. I’ve always wondered how to manage my memory better and how to optimize my game, as I am running Acer Aspire A515 with only 8gb of RAM with Ubuntu 23.10, and I am relying on integrated performance. I also didn’t care about school up until recently, so now I’m trying to incorporate a bunch of math into my game and I don’t understand any of it, so if anyone could point me into the right direction for learning math from a computer science and game dev standpoint that would also be very helpful.

If anyone wants anymore information please let me know.

I tried commenting out the draw method to see if that was the problem, and I also checked to make sure I’m not creating a bunch of sword objects on accident.
