The pygame window gets really laggy when i try to run it. I have 132 lines of code so far and i have loads more stuff to add. While test-running i noticed that the game satrted lagging when i added the following bits of code in
class Game:
def __init__(self):
self.win = pygame.display
self.d = self.win.set_mode((1200, 600))
self.win.set_caption(" JUMP ")
self.timee = 0
def write(self, size, writing, color, x, y):
font = pygame.font.SysFont("nirmalauisemilight", size)
text = font.render(writing, True, color)
self.d.blit(text, (x, y))
def game_over(self):
if b.y >= ba.y - b.side and self.timee > 5:
while True:
self.write(200, "GAME OVER", (255, 0, 0), 20, 50)
self.write(50, "Press enter to satart a new game", (0, 255, 0), 100, 400)
pygame.event.get()
keys = pygame.key.get_pressed()
if keys[pygame.K_RETURN]:
main()
g.win.flip()
AND
def draw(self):
if g.timee < 5:
pygame.draw.rect(g.d, (0, 255, 0), (self.x, self.y, self.width, self.height))
else:
pygame.draw.rect(g.d, (255, 0, 0), (self.x, self.y, self.width, self.height))
g.timee is a variable i made so i can execute some functions after a cartain time into the game. g.timee is incremented by 0.01 in the main loop. I tried using time module's time.time() fucntion as well but it lagged the game even more. Any advice on how to reduce lagging would be appreciated.
EDIT
while looking through other questions i came across cPrifile and using that i got this data

I am not entirely sure what it means though.

pygame.time.Clock().tick(60)
main()
I figured it out. Its because my pygame.time.Clock().tick(60) was in the game loop. Not sure why this was causing lag but for anyone who might be having the same issue, dont put it in the main loop.
