player rect leaves player image and goes outside camera in pygame

Question

My player is blitted exactly in the middle of the screen. However when I move the player right and left even though the camera follows the player image, the player rect moves faster than the image itself and goes outside screen at some point. I tried many things and I'm not sure what is wrong here. I've been stuck in here for hours, please help me.

import pygame,sys
pygame.init()

windowsize=(800,600)
display=pygame.display.set_mode(windowsize)
screen=pygame.Surface((600,400))
main_running=True

playerrect = pygame.Rect(300 ,300, 32, 32)



playeridle=[]
for i in range(1,17):
    playeridle.append(pygame.image.load("player\playeridle (%s).png"%i))


movingleft=False
movingright=False
jump=False



true_scroll=[0,0]


timer=0
stay=0
while main_running:
    screen.fill((0,0,0))


    true_scroll[0] += (playerrect.x-true_scroll[0]-300)/20
    true_scroll[1] += (playerrect.y-true_scroll[1]-300)/20
    scroll = true_scroll.copy()
    scroll[0] = int(scroll[0])
    scroll[1] = int(scroll[1])
    playerx=playerrect.x-scroll[0]
    playery=playerrect.y-scroll[1]





    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            pygame.quit()
            sys.exit()
        if event.type==pygame.KEYDOWN:
            if event.key==pygame.K_LEFT:
                movingleft=True
            if event.key==pygame.K_RIGHT:
                movingright=True
            if event.key==pygame.K_SPACE:
                jump=True

        if event.type==pygame.KEYUP:
            if event.key==pygame.K_LEFT:
                movingleft=False
            if event.key==pygame.K_RIGHT:
                movingright=False
            if event.key==pygame.K_SPACE:
                jump=False



    player_movementx=0
    player_movementy=0
    if movingleft:
        player_movementx=-5
    if movingright:
        player_movementx=+5
    player_movementy+=0.2
    if player_movementy>=7:
        player_movementy=7


    playerrect.x+=player_movementx
    playerrect.y+=player_movementy

    rect=pygame.Rect(0-scroll[0],300-scroll[1],600,50)
    pygame.draw.rect(screen,(0,255,255),rect)



    #playeranimations
    timer+=1
    if timer>=5:
        stay+=1
        timer=0
    if stay>=16:
        stay=0

    screen.blit(playeridle[stay],(playerx,playery))
    pygame.draw.rect(screen,(255,0,0),playerrect,1)


    pygame.time.delay(30)
    display.blit(pygame.transform.scale(screen, windowsize), (0, 0))
    pygame.display.update()

As `playerx=playerrect.x-scroll[0]`, `playerx` is smaller then `playerrect.x`. The rect is following the real in-game position, while `playerx` is tracking the position of the image, including scroll. As `playerx` is used for drawing the image, it is logic that the position of the rect and the image differs. — The_spider, May 27 '22 at 18:29
What is exactly the problem with the rect and camera position differing? Is the output on the screen wrong? — The_spider, May 28 '22 at 07:22
yes the camera stays focus on the image which stays in the middle but the rect kinda moves on its own,the world scrolls too but not as fast as the rect and the rect eventually goes outside the display — Crimson Reaper, Jun 02 '22 at 04:25
