Why aren't my variables working in the while loop - pygame

Question

for some reason when i blit my image and try to move my cube, it doesn't work and my text doesn't work either.
import pygame
from random import randint
pygame.init()
pygame.font.init()
HEIGHT = 600
WIDTH = 800
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Cube game")
clock = pygame.time.Clock()
TP_usage = 0
FPS = 60
Cube_Vel = 4
HP = 3
CubeX = 400
CubeY = 400
TP_staff = pygame.image.load("Game imag/TP staff.png")
TP_staff_rect = TP_staff.get_rect(center=(randint(10, 500), (randint(10, 770))))
No_tp_text = pygame.font.Font(None, 50)
No_tp_Warning = No_tp_text.render("NO TP USAGE", False, "white")
TP_usage_Stat_Font = pygame.font.Font(None, 30)
TP_usage_Stat = TP_usage_Stat_Font.render(f"TP usages: {TP_usage}", False, "white")
Cube_player = pygame.image.load("Game imag/Cube.png")
Cube_player_rect = Cube_player.get_rect(center=(CubeX, CubeY))
while True:
clock.tick(FPS)
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
#part that is not updating
screen.fill((0, 0, 0))
screen.blit(TP_usage_Stat, (500, 600))
screen.blit(Cube_player, Cube_player_rect)
screen.blit(TP_staff, TP_staff_rect)
if Cube_player_rect.colliderect(TP_staff_rect):
TP_usage += 1
print(TP_usage)
if TP_usage > 1:
TP_usage = 1
print(TP_usage)
keys = pygame.key.get_pressed()
if keys[pygame.K_a] and CubeX - Cube_Vel > 0:
CubeX -= Cube_Vel
if keys[pygame.K_d] and CubeX + Cube_Vel < WIDTH:
CubeX += Cube_Vel
if keys[pygame.K_w] and CubeY - Cube_Vel > 0:
CubeY -= Cube_Vel
if keys[pygame.K_s] and CubeY + Cube_Vel < HEIGHT:
CubeY += Cube_Vel
pressed_keys = pygame.mouse.get_pressed()
if (pressed_keys[0]) and TP_usage > 0:
TP_usage -= 1
print(TP_usage)
mx, my = pygame.mouse.get_pos()
CubeX = mx
CubeY = my
if (pressed_keys[0]) and TP_usage < 0:
screen.blit(No_tp_Warning, (400, 500))
pygame.display.update()
before i had it something like this
import pygame
from random import randint
pygame.init()
pygame.font.init()
HEIGHT = 600
WIDTH = 800
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Cube game")
clock = pygame.time.Clock()
TP_usage = 0
PhoX = 100
PhoY = -200
FPS = 60
Cube_Vel = 4
HP = 3
CubeX = 400
CubeY = 400
TP_staff = pygame.image.load("Game imag/TP staff.png")
TP_usage_Stat_Font = pygame.font.Font(None, 30)
TP_usage_Stat = TP_usage_Stat_Font.render(f"TP usages: {TP_usage}", False, "white")
Cube_player = pygame.image.load("Game imag/Cube.png")
# Timer
obstacle_timer = pygame.USEREVENT + 1
pygame.time.set_timer(obstacle_timer, 5000)
TP_staff_rect = TP_staff.get_rect(center=(randint(10, 500), (randint(10, 770))))
game_on = True
while True:
No_tp_text = pygame.font.Font(None, 50)
No_tp_Warning = No_tp_text.render("NO TP USAGE", False, "white")
Cube_player_rect = Cube_player.get_rect(center=(CubeX, CubeY))
clock.tick(FPS)
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
screen.fill((0, 0, 0))
screen.blit(TP_usage_Stat, (500, 600))
screen.blit(Cube_player, Cube_player_rect)
screen.blit(TP_staff, TP_staff_rect)
if event.type == obstacle_timer:
TP_staff_rect = TP_staff.get_rect(center=(randint(10, 500), (randint(10, 770))))
if Cube_player_rect.colliderect(TP_staff_rect):
TP_usage += 1
print(TP_usage)
if TP_usage > 1:
TP_usage = 1
print(TP_usage)
keys = pygame.key.get_pressed()
if keys[pygame.K_a] and CubeX - Cube_Vel > 0:
CubeX -= Cube_Vel
if keys[pygame.K_d] and CubeX + Cube_Vel < WIDTH:
CubeX += Cube_Vel
if keys[pygame.K_w] and CubeY - Cube_Vel > 0:
CubeY -= Cube_Vel
if keys[pygame.K_s] and CubeY + Cube_Vel < HEIGHT:
CubeY += Cube_Vel
pressed_keys = pygame.mouse.get_pressed()
if (pressed_keys[0]) and TP_usage > 0:
TP_usage -= 1
print(TP_usage)
mx, my = pygame.mouse.get_pos()
CubeX = mx
CubeY = my
if (pressed_keys[0]) and TP_usage < 0:
screen.blit(No_tp_Warning, (400, 500))
pygame.display.update()
the problem was it was going everywhere 60 times a sec so i tried to move the staff rect out of the while loop and then everything else as will but now nothing is updating like normal

Your game updates normally. The problem is that you move with Cube_player and you also draw Cube_player_rect. Here's how to solve it:
keys = pygame.key.get_pressed()
if keys[pygame.K_a] and Cube_player_rect.x - Cube_Vel > 0:
Cube_player_rect.x -= Cube_Vel
if keys[pygame.K_d] and Cube_player_rect.x + Cube_Vel < WIDTH - Cube_player_rect.w:
Cube_player_rect.x += Cube_Vel
if keys[pygame.K_w] and Cube_player_rect.y - Cube_Vel > 0:
Cube_player_rect.y -= Cube_Vel
if keys[pygame.K_s] and Cube_player_rect.y + Cube_Vel < HEIGHT - Cube_player_rect.h:
Cube_player_rect.y += Cube_Vel
pressed_keys = pygame.mouse.get_pressed()
if (pressed_keys[0]) and TP_usage > 0:
TP_usage -= 1
print(TP_usage)
mx, my = pygame.mouse.get_pos()
Cube_player_rect.x = mx
Cube_player_rect.y = my
if (pressed_keys[0]) and TP_usage < 0:
screen.blit(No_tp_Warning, (400, 400))
The font does not draw to you because it has y coordinates outside the image. TP_usage is not updated because you draw an old variable. Try my function for drawing text:
def draw_text(text, color, size, x, y):
font = pygame.font.Font(None, size)
text = font.render(text, False, color)
text_rect = text.get_rect(center=(x, y))
screen.blit(text, text_rect)
This is how you use in main loop:
draw_text(f"TP usages: {TP_usage}", "white", 30, 500, 500)
I hope it will help you, Adam
