How to draw with mouse and save as 1s and 0s

How to draw with mouse and save as 1s and 0s - python-3.x

I have implemented a custom level code on my main game. But i need a Level editor to make it easier to make custom levels. I have use buttons to cover the screen and when clicked, it will place a block (print down below is a test, it'll help me greatly if you combine the code with my main problem. Weirdly, It not printing and lagging so i need code to draw and export as the format i need (Format in Code).

Why do you need a button?
Calculate the index of the cell when the mouse is pressed:
column = event.pos[0] // TILESIZE
row = event.pos[1] // TILESIZE
And switch the state of the cell
tm[row][column] = 1 if tm[row][column] == 0 else 0
e.g.:
while True:
for event in pygame.event.get():
pos = pygame.mouse.get_pos()
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.MOUSEBUTTONDOWN:
column = event.pos[0] // TILESIZE
row = event.pos[1] // TILESIZE
if row < len(tm) and column < len(tm[row]):
tm[row][column] = 1 if tm[row][column] == 0 else 0
screen.fill(white)
for row in range(HEIGHT):
for column in range(WIDTH):
c = grey if tm[row][column] == 1 else (255,255,255)
pygame.draw.rect(screen, c, [column*TILESIZE, row*TILESIZE, TILESIZE, TILESIZE])
pygame.display.update()
clock.tick(60)
Additionally you can highlight" the cell where the mouse is on and draw a text which contains the row and column of the cell:
class button():
def __init__(self, color, x,y,width,height, text=''):
self.color = color
self.x = x
self.y = y
self.width = width
self.height = height
self.font = font = pygame.font.SysFont('comicsans', 20)
def draw(self, win, x, y):
pygame.draw.rect(win, self.color, (self.x,self.y,self.width,self.height),0)
text = self.font.render(str(x) + " / " + str(y), 1, (0,0,0))
screen.blit(text, (round(self.x) + (round(self.width/2) - round(text.get_width()/2)), round(self.y) + (round(self.height/2) - round(text.get_height()/2))))
buttonD = button((0,255,0), 640, 360, 20, 20, ' ')
while True:
for event in pygame.event.get():
pos = pygame.mouse.get_pos()
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.MOUSEBUTTONDOWN:
column, row = event.pos[0] // TILESIZE, event.pos[1] // TILESIZE
if row < len(tm) and column < len(tm[row]):
tm[row][column] = 1 if tm[row][column] == 0 else 0
mouse_pos = pygame.mouse.get_pos()
mcol, mrow = mouse_pos[0] // TILESIZE, mouse_pos[1] // TILESIZE
buttonD.x, buttonD.y = mcol*TILESIZE, mrow*TILESIZE
screen.fill(white)
for row in range(HEIGHT):
for column in range(WIDTH):
c = grey if tm[row][column] == 1 else (255,255,255)
pygame.draw.rect(screen, c, [column*TILESIZE, row*TILESIZE, TILESIZE, TILESIZE])
buttonD.draw(screen, mcol, mrow)
pygame.display.update()
clock.tick(60)

Pygame code very slow despite all troubleshooting

so i wrote this game from a pygame intro tutorial, added menus and all to modify it. whenever i run the game on my MBP 17, it runs extremely slow. i googled it, and tried all solutions, to no avail. also, typing in my event.unicode works extremely horribly, i have to press the same key more than once for it to register. any help is appreciated.

The problem is that you are calling pygame.event.get() multiple times (Lines: 89, 174, 208). This causes different events queues to disagree and causes problems. There is an easy fix.
In you main application loop, call pygame.event.get() once.
def game:
while running:
#omitted code
events = pygame.event.get()
for event in events:
#...
Then, you can pass events variable to other functions as an argument.

Why is the circle moving in a straight line instead of at an angle in pygame?

I am learning the basics of pygame in my free time at work. I wanted to move the bottom boundary of my program up, but when I changed the boundary collision condition, the ball moves in a straight line instead of at an angle.
When I delete the 525 part of the condition in the bounceCircle definition, it moves as expected. When I place it back, it moves in a horizontal line.

You need to edit the bounceCircle function to:

if (self.x + self.radius > width ) or (self.x - self.radius < 0):
self.angle = - self.angle
elif (self.y + self.radius > (525)) or (self.y - self.radius < 0):

Python Pygame Personal Module Error

So I was cleaning up my code by adding in classes, in order to put certain tools that I will be using in my game, into other files. SO as I was kinda learning and implementing, I stumbled upon an easy error that I can't find out for the life of me.
So I have my core.py and pyWMouse.py in the same folder. My pyWMouse.py just has my mouse tools that I created. I keep getting this error:

Thanks for your time everyone. Much appreciated.

I believe the problem can be found in core.py. Try changing :
userMouse = pyWMouse.MouseTools
to the following:
userMouse = pyWMouse.MouseTools()
Adding the missing parentheses should do the trick.

Piano tiles: background image

I'm trying to make piano tiles in python using pygame. So, I've started with making an intro window but I'm unable to upload a background image1 in my into window. I actually want to display the name 'Piano tiles' and the background image whenever the player starts the game. Here's my code:
import pygame,os,random,time
from pygame.locals import *
wix=800
wiy=800
pygame.init()
white=(255,255,255)
black = (0,0,0)
red = (255,0,0)

medfont = pygame.font.SysFont("comicsansms", 50)
largefont = pygame.font.SysFont("comicsansms", 100)

pygame.display.set_caption("Piano Tiles")
def game_intro():
screen=pygame.display.set_mode((wix,wiy))

while intro:

screen.blit(bg,(0,0))

if size == "small":
textSurface = smallfont.render(text, True, color)
elif size == "medium":
textSurface = medfont.render(text, True, color)
elif size == "large":
textSurface = largefont.render(text, True, color)
return textSurface, textSurface.get_rect()
def message_to_screen(msg,color, y_displace=0, size = "small"):
textSurf, textRect = text_objects(msg,color, size)

gameDisplay.blit(textSurf, textRect)
game_intro()
pygame.time.wait(4000)
pygame.quit()

You have to use fill(white) before you blit anything because it clear screen.
It could look like this

#fonts = {"small": small_font, "medium": med_font, "large": large_font}
#font = fonts[size]
text_surface = font.render(text, True, color)
text_rect = text_surface.get_rect()
return text_surface, text_rect
def message_to_screen(screen, msg, color, y_displace=0, size="small"):
text_surface, text_rect = text_objects(msg, color, size)
text_rect.center = screen.get_rect().center
text_rect.y += y_displace
screen.blit(text_surface, text_rect)

#bg = pygame.image.load("background.jpg")

screen.blit(bg, (0,0))

I'm a student and this game is one of my task. when the player win or loose, pressanykeytostart() doesn't work. however in the beginning it works. Also I get this error massage (Pygame Error: Video System not Initialized) every time I play.
How can I add a Pause function in my game?
