I am working on my first coding project made in pygame and I have an issue with the rotation of the player. I want to make the player point towards the center of its circular path, but it doesn’t work correctly and I don’t know why.
My code so far:

import pygame
import math
pygame.init()

w=1920
h=1040
win=pygame.display.set_mode((w,h))

pygame.display.set_caption("Quan")

clock = pygame.time.Clock()

a=0
b=0
k1=w/2
k2=h/2
x=k1+math.cos(a)*500
y=k2+math.sin(b)*500
angle_var=0.01
image=pygame.image.load('arrow.png')
image = pygame.transform.rotate(image, 180)

def walk():
    win.blit(image,(x,y))
    pygame.display.update()

run=True
while run:
    clock.tick(60)
    
    pygame.time.delay(10)
    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
            
    keys = pygame.key.get_pressed()
    if keys[pygame.K_d]:
        a+=angle_var
        b-=angle_var
        x=(k1+math.cos(a)*500)
        y=(k2+math.sin(b)*500)
        image = pygame.transform.rotate(image, angle_var)
    if keys[pygame.K_a]:
        a-=angle_var
        b+=angle_var
        x=k1+math.cos(a)*500
        y=k2+math.sin(b)*500
        image = pygame.transform.rotate(image, -1*angle_var)

    walk()
    win.fill((0,0,0))


        
pygame.quit()

I’m sorry if it’s a mess, its my first time coding in this.
Thank you

I tried to change the rotation, but it did not work properly.
