How to avoid moving in the opossite direction - python

I'm implementing and "IA" to my ghost in my copy of Pac-Man, the ghost when hit a block check for every way it can go, but one of that ways is the opposite direction he was taking and that makes that for example if hits a block while moving left, then move right, and then hit a block and move left again, how can I avoid that? I tried doing a "oppositeDirection" variable that changes depending where it the block but the ghost keep doig the same

Keep track of the direction he was heading. Make the opposite of that direction be the last possible choice. If you want to do a little more work, keep track of each block visited (a simple Boolean map), and when there is a choice to make, then sort the directions of any visited blocks to the end of the choice list.

Trying to remove objects of the screen

I'm making a copy of Pac-Man with Python and Pygame, but I'm having a problem when trying to delete the dots a pills, I'm not sure of how to do it I tried to use "del" and didn't work, I also tried adding the dots to a list and then make a for loop that iterates in every dot and remove it if the player collide with one of them, but it makes the game to laggy, how can I remove the pills from the screen?

I do not know how to end game when specific block is touched in pygame

I want to make it so when my character touches the "v" block the game quits. What I tried was to find all blocks that are "v" and put them in the list. If player colliderect with any in list of "v" game will quit.
I think this should work although it does not seem to be working. Whenever I run it when I touch the "v" block nothing happens.

You do not detect a collision with the spikes, because your collision detection works too perfectly.
When you move the player then you ensure, that the player does not intersect any object, thus the player does not intersect a spike, too.
You have to test if the player touches a spike. Increase the player rectangle by 1 in direction and use the increased rectangle to do the collision test with the spikes:
while run:
# [...]
test_rect = pygame.Rect(player_rect.left-1, player_rect.top-1,
player_rect.width+2, player_rect.height+2)
for spike in list_ofspike:
if test_rect.colliderect(spike):
pygame.quit()
# [...]

textRect1 = text1.get_rect()
textRect1.center = (button_1.centerx, button_1.centery)
screen.blit(text1, textRect1)
mx, my = pygame.mouse.get_pos()
if button_1.collidepoint((mx, my)):
if click:
game()
if button_2.collidepoint((mx, my)):

options()
click = False
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()

pygame.quit()
sys.exit()
if event.type == MOUSEBUTTONDOWN:
if event.button == 1:
click = True
pygame.display.update()
clock.tick(60)
How do I make it so that after button_1 is pressed, there's a 3,2,1 countdown on the screen, and then the game starts?
In order to do the countdown, you import the time module:
import time
...then you need a for loop, with a step -1, counting down from 3 to 1. Inside the for loop, print the numbers and sleep one second, using the time module:
for a in range(3,0,-1):
print(a)
time.sleep(1)
After this for loop, you put the rest of your code.

Collision not working Pygame

I'm making a game with pygame, Space Invaders, and now I'm doing the collisions between the shoot of the eneimies and the player (those are images), but it doesn't work all time and I'd like to know why, and what's the solution.
Thanks for attention!

Here is a collision detection code that will sense if one rectangle collides with another rectangle, if the enemy's shot hits the player:
if player x < shot x + player width and player x + shot width > shot x and player y < shot y + player height and shot height + player_y > shot y:
It works by sensing if any of the edges of the bullet are touching any edges of the character. I hope this helps.

Variables and Surface won't Update in Python/Pygame

I am trying to make my game have special abilities for the player, but am having some issues. For some reason user_health_active and user_health_display_active do not update after reaching round 10. I can't figure out why this is and have been attempting to for about two hours. By the seems of it, not only does the surface not update, but the actual background function doesn't either. If anyone can provide me some insight on why this isn't working, please let me know. Here is my code.

The code that modifies the variables you mention will never be run. Here's the relevant bit:
if game_level_score > 4:
user_teleport_active = True
user_teleport_display_active = ("True")
elif game_level_score > 9:
user_health_active = True
user_health_display_active = ("True")
Because you're using an if and an elif, the condition for the second block is only ever tested if the first block's condition was false. Since any value greater than 9 is also going to be greater than 4, the second block will never run.
If you want the two conditions to be tested independently, you need to just use plain if statements for both conditions. If you only want one block to run , you either need to extend the first condition to 4 < game_level_score <= 9 or you need to change the order so that the > 9 test comes before the > 4 test.
