When my player sprite collides with the coin group the coins disappear as wanted, but when it collides with the enemys group nothing happens. The code is the same. I don't know what I did wrong because I did the same thing twice but it only works once. Does it have anything to do with the enemys moving? Here is the the code:

I also don't get any errors because of this.
The way you add and remove the gegner instances causes this problem. The enemys_group contains the gegners in the beginning and is used for the collision detection. That means you can already collide with them before they are visible (print the groups and hit in the for hit in hits: loop to check this). If you hit an instance, it is removed from the enemys_group correctly.
Then if you reach a score of 5 or higher you keep adding the instances, that are still bound to the gegner1, etc. variables, to the all_sprites group each frame, so the sprites become visible, but if they're not in the enemys_group they can't collide anymore.
You need to restructure the code. I'd leave the enemys_group empty at the beginning and then add the gegner instances in the coin collision loop:
hits = pg.sprite.spritecollide(player, coin_group, True, pg.sprite.collide_circle)
for hit in hits:
score += 1
new_coin()
if score == 5:
gegner = Gegner_1(0, 60, 'yes')
all_sprites.add(gegner)
enemys_group.add(gegner)
elif score == 10:
gegner = Gegner_1(width, 350, 'yes')
all_sprites.add(gegner)
enemys_group.add(gegner)
elif score == 15:
gegner = Gegner_1(50, p_height, 'no')
all_sprites.add(gegner)
enemys_group.add(gegner)
elif score == 20:
gegner = Gegner_1(width - p_width - 20, p_height, 'no')
all_sprites.add(gegner)
enemys_group.add(gegner)

I get the code on YOUTUBE
and edit the code a little bits
but I did not add the restart code
How can I make the restart function in pygame?
I just want to over the game when player get a 5 score in the game.
and want to make the game restart.
When the game is overed, the player can restart the game with the button.
To restart you will need to reset any variables that change during the game. Write a function that sets all objects and variables to its initial state:
def reset():
global player_paddle, cpu_paddle, pong
global cpu_score, player_score
global live_ball, winner, speed_increase
player_paddle = paddle(screen_width - 40, screen_height // 2)
cpu_paddle = paddle(20, screen_height // 2)
pong = ball(screen_width - 60, screen_height // 2 + 50)
cpu_score = 0
player_score = 0
live_ball = False
winner = 0
speed_increase = 0
Call the function when you want to restart the game.
Have the loop it's own method, call it from a main() run, when the game is over and ends, have main() ask the user if they want to play again, and if so recall the main loop after setting everything as its default
or
Just have the part that asks again clear and reinitialize all variables as there defaults and let the loop if the user wants to play again
I've made a game in pygame and I want to make it possible to have a high score thaat will be displayed at the the top of the show_go_screen. I just need a simple solution - I don't need to write who has the highest score, just the number itself at the top of the show_go_screen. I know there are already questions about this on Stack Overflow but the solutions don't work for me.

Create a variable called highscore then then when the player looses, check if the current score is higher than highscore and if it is, then assign the score to highscore. Then you can just easily add a label with the highscore variable as a text
score = 0
highscore = 0
# save score
# import shelve
# d = shelve.open('score.txt') # here you will save the score variable
# d['highscore'] = score # thats all, now it is saved on disk.
# d.close()
# A lot of your code
def show_go_screen():
screen.blit(background2, background_rect2)
draw_text(screen, str(highscore), 50, WIDTH / 2, 10) #change the x value accordingly
# more of your code

I am writing a snake game with pygame but I am just prompted with a black window without any error.
I checked similar problems and they incorrectly used the screen object. However this does not seem to be the case here, since it is only created once?
Any idea what I am doing wrong? Since I am not given any error message I can't figure out why I am only shown a black screen. The key input events work just fine.

The update of the display and the drawing of the sprites has to be done in the main loop rather than in the inner for loop:
while running:
# [...]
for i in range(1, len(player.tail)):
pygame.draw.rect(screen, WHITE, (player.tail[i][0], player.tail[i][2], 12, 12))
# <--
all_sprites.draw(screen)
pygame.display.flip()
Note, if the snake consists of a head only, then the inner loop is not executed. If the length of the tail would be > 1, then the display would be updated multiple times per frame, which is not what you want.
I am getting an out of range exception
Traceback (most recent call last): File "snake.py", line 132, in <module> >
pygame.draw.rect(screen, WHITE, (player.tail[i][0], player.tail[i][2], 12, 12))
IndexError: tuple index out of range `
The index of the 2nd (y) coordinate is 1 rather than 2. Ist has to be player.tail[i][1]:
for i in range(1, len(player.tail)):
pygame.draw.rect(screen, WHITE, (player.tail[i][0], player.tail[i][1], 12, 12))
If you play the game and win, clicking on the screen will cause the game to play again. On the second play, the game segmentation faults after a second or two.
This code is for an intro to coding class and many others have coded this game successfully. I don't understand what is the problem here.
Help!

I wanted to add a sorta ammo clip thing in my shooter game, its very simple all I do is blit I * the ammount of ammo, but I wanted there to be three lines to show the clip like so:
IIIIIIIIIIIIIIIIIIIIII
IIIIIIIIIIIIIIIIIIIIII
IIIIIIIIIIIIIIIIIIIIII
Each line has 35 ammo symbols but if the player has more than 95 ammo I wanted it to blit that anount as a number next to the ammo clip, but no matter how much ammo I have it never blits the number and no matter how much ammo I have at the start it never blits more than this at the start until I collect a ammo box:
IIIIIIIIII
I really cant find out why it is doing this, I've tryed changing the amount it blits and many other things but nothing seems to work, so hear is my code:
#wave font
font = pygame.font.SysFont("", 34)
self.text_pause = font.render("WAVE " + str(self.wave) * self.blitwave, -1, RED)
self.text_pause_rect = self.text_pause.get_rect(center=self.screen.get_rect().center) # center text
texthealth = int(self.health / 10)
#health font
self.text_health = font.render("o" * texthealth, -1, RED)
#score font
self.text_score = font.render("SCORE " + str(self.score), -1, BLACK)
#cash font
self.text_cash = font.render(str(self.cash), -1, GREEN)
#ammo font
self.text_ammoS = font.render("I" * 35, -1, RED)
self.text_ammo = font.render("I" * self.ammo_amount, -1, RED)
self.text_ammoW = font.render("I" * (self.ammo_amount - 35), -1, RED)

Thank you so much for your time and help.
You don't blit ammo number - see # in line:
#self.screen.blit(self.text_ammo, (450, 610))
And it has to be text_ammoN not text_ammo
By the way:
You have to much code in main loop - put some code in functions like update_wave_text() , update_ammo_text(), etc. , blit_wave_text(), blit_ammo_tex(), etc.
Use self.: in __init__ set
self.screen_width = 850
self.screen_height = 640
and than use self.screen_width, self.screen_height and you will not have to repeat
screen_width = 850
screen_height = 640
