Eh...mixer is an audio library. Why should I need that, for the game?
And ttf impairs the power of my computer. It makes my computer slower.

What do I need it for?

RE: A 4x4 Field in Pygame - metulburr - Aug-19-2019

sdl-mixer does anything audio related. sdl-ttf is for fonts.

pygame.init() initializes everything, including mixer and ttf. So if you want to do that you need to install the dependencies.

How many games have you played without sound.

It for fonts. Making text in pygame.
Like to know how this makes your computer runs slower ?
Only time code would be run. If you creating a font or rendering to pygame surface.

How would you run other examples? That uses these.

But I can also use sys for making fonts in pygame. Here's a little example of how I did that once:

import pygame
import random
import sys

go = True

pygame.init()
screen = pygame.display.set_mode([500,500])
BackGround = pygame.image.load("background.jpg")
screen.blit(BackGround, (0,0))
pygame.display.set_caption('Pygame test')
pygame.display.flip()

font = pygame.font.SysFont(None, 60)

def writetext(outputtext,colour):
    text = font.render(outputtext, True, colour)
    size_rect = text.get_rect(center = (500/2, 54))
    screen.blit(text,size_rect)
    pygame.display.flip()

while go:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        if event.type == pygame.MOUSEBUTTONDOWN:
            x = random.randint(1,2)
            screen.blit(BackGround, (0,0))
            if x == 1:
                writetext("Yes!", (255,255,255))
            elif x == 2:
                writetext("No!", (255,255,255))

I think, I can do it with sys too. What do you think?

RE: A 4x4 Field in Pygame - metulburr - Aug-19-2019

This is using all modules as you have initialized them here on line 7

pygame.init()

So in your code you are already initializing mixer and ttf

You can uses system fonts, but from my experience its not a good idea when packaging a game. For example some people may have certain fonts on their system while others not, causing an error for them. Its much more solid if you just send a font along with your program.

PS you dont need all those flips everywhere.

import pygame
import random
import sys
 
go = True
 
pygame.init()
screen = pygame.display.set_mode([500,500])
pygame.display.set_caption('Pygame test')
 
font = pygame.font.SysFont(None, 60)
 
def writetext(outputtext,colour):
    text = font.render(outputtext, True, colour)
    size_rect = text.get_rect(center = (500/2, 54))
    screen.blit(text,size_rect)
 
while go:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        if event.type == pygame.MOUSEBUTTONDOWN:
            x = random.randint(1,2)
            if x == 1:
                writetext("Yes!", (255,255,255))
            elif x == 2:
                writetext("No!", (255,255,255))
    pygame.display.update()

RE: A 4x4 Field in Pygame - Windspar - Aug-19-2019

Reason for one update.
1. It can cause flickering.
2. It will slow down main loop.

Another thing. Always render text before main loop.
Otherwise you are using resources for no reasons.
This also will slow down main loop.

You want to get into structuring your code. It will help you learn.
Here a start. Also creating text before main loop and how to blit text in main loop.

import pygame
import random
import sys

def create_text(font, output_text, colour, position):
    text = font.render(output_text, True, colour)
    rect = text.get_rect(center=position)
    return text, rect

def draw_text(surface, data):
    surface.blit(data[0], data[1])

def main_loop(surface, images):
    text_image = None

    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()
            if event.type == pygame.MOUSEBUTTONDOWN:
                x = random.randint(1,2)
                if x == 1:
                    text_image = images['yes']
                elif x == 2:
                    text_image = images['no']

        # clear main surface
        surface.fill(pygame.Color('black'))
        if text_image:
            draw_text(surface, text_image)

        # render main surface to screen
        pygame.display.update()

def main():
    pygame.init()
    surface = pygame.display.set_mode([500,500])
    pygame.display.set_caption('Pygame test')

    position = surface.get_width() / 2, 54
    font = pygame.font.SysFont(None, 60)

    images = {
        'yes': create_text(font, 'Yes', pygame.Color('white'), position),
        'no': create_text(font, 'No', pygame.Color('white'), position)
    }

    main_loop(surface, images)

main()

RE: A 4x4 Field in Pygame - Piethon - Aug-19-2019

So know, I wanted to create the script, I've asked for in this tread.
Till know, nothing is happening, when I run the code, but I don't get an error.

import pygame
import sys

pygame.init()

  
screen = pygame.display.set_mode([500,500])
BackGround = pygame.image.load("white.png")
screen.blit(BackGround, (0,0))
pygame.display.set_caption("Pusqumbers")
pygame.display.flip()


mapDict = {}

for x in range(1, 17): #repeat 16 times
    mapDict.update({x : None}) #None means it isn't occupied
    
def can_move(x, y):
    if 0 <= x < 4 and 0 <= y < 4:
        return True
    return False

Thanks for your advices, with the example code, I showed above! :-)

RE: A 4x4 Field in Pygame - Windspar - Aug-19-2019

Tell us what you want the code to do next time.
Why would there be an error.
You don't have a loop.
You do stuff after flip.
If you want to see what in mapDict. Then print it.

Nothing is happening because you dont have a main game loop to keep it open. It just runs to the end of the script and closes within a millisecond.

RE: A 4x4 Field in Pygame - Piethon - Aug-20-2019

Sorry forgot the loop!

import pygame
import sys

pygame.init()

  
screen = pygame.display.set_mode([500,500])
BackGround = pygame.image.load("white.png")
screen.blit(BackGround, (0,0))
pygame.display.set_caption("Pusqumbers")


go = True

while go:
    mapDict = {print("Hello")}

    for x in range(1, 17): #repeat 16 times
        mapDict.update({x : None}) #None means it isn't occupied
    
    def can_move(x, y):
        if 0 <= x < 4 and 0 <= y < 4:
            return True
        return False
 
pygame.display.flip()

My only problem is know, that I just have an empty window called "pygame window" and it is just loading endlessly and nothing shows up inside the window.
