pygame display not changing - python

I'm trying to write my first game in pygame and successfully made a title screen, but can't find a way to make the 'play' button take the user to the actual gameplay. I have a function dedicated to the title screen, and when the user clicks the play button it stops the title screen loop and starts the gameplay loop, although the gameplay loop code doesn't work. The title screen just freezes and the game doesn't start. I also have never used Stack overflow so I'll just paste my code here I guess:

# set display

I went through your code, and I haven't seen an update once.
So since it's your first here's a quick lesson:
when there is any movement, any changes, anything that is changing on your window it won't show up unless you update it, using:
pygame.display.update()
or
pygame.display.flip()
When outputting things, think of them as layers, if you output one image, and then a second image. The first image won't show.
(That's if they are the same size but you know what I mean.)

how to get position of touch from pygame.FINGERDOWN in android? [duplicate]

Game Target is for android device.
When i add the buttons, they seem only to work one at a time, how can i make it so more button could work?
Here's the function:
def button_move(player_car):
pressed = pygame.mouse.get_pressed()
pos = pygame.mouse.get_pos()
moved = False
if pressed[0] == 1:
if 300 < pos[0] < 400 and 800 < pos[1] < 900:
player_car.move_forward()
moved = True
if 300 < pos[0] < 400 and 1100 < pos[1] < 1200:
player_car.move_backward()
moved = True
if 100 < pos[0] < 200 and 950 < pos[1] < 1050:
player_car.rotate(left=True)
if 500 < pos[0] < 600 and 950 < pos[1] < 1050:
player_car.rotate(right=True)
if not moved:
player_car.reduce_speed()
[...] they seem only to work one at a time [...]"
You only have one mouse. You have to use the "touch" events. Use the FINGERDOWN and FINGERUP event. Store the position of the finger into a dictionary when a FINGERDOWN event occurs and remove it on FINGERUP:
fingers = {}
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
if event.type == pygame.FINGERDOWN:
x = event.x * window.get_height()
y = event.y * window.get_width()
fingers[event.finger_id] = x, y
if event.type == pygame.FINGERUP:
fingers.pop(event.finger_id, None)
# [...]
Use the positions to detect if a button is touched. Use pygame.Rect and pygame.Rect.collidepoint for the "touch" detection. e.g.:
rect = pygame.Rect(300, 800, 100, 100)
touched = False
for finger, pos in fingers.items():
if rect.collidepoint(pos):
touched = True
Minimal example:
import pygame
pygame.init()
window = pygame.display.set_mode((300, 300))
clock = pygame.time.Clock()
buttons = [
pygame.Rect(25, 25, 100, 100),
pygame.Rect(175, 25, 100, 100),
pygame.Rect(25, 175, 100, 100),
pygame.Rect(175, 175, 100, 100)]
colors = [(64, 0, 0), (64, 64, 0), (0, 64, 0), (0, 0, 64)]
colorsH = [(255, 0, 0), (255, 255, 0), (0, 255, 0), (0, 0, 255)]
fingers = {}
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
if event.type == pygame.FINGERDOWN:
x = event.x * window.get_height()
y = event.y * window.get_width()
fingers[event.finger_id] = x, y
if event.type == pygame.FINGERUP:
fingers.pop(event.finger_id, None)
highlight = []
for i, rect in enumerate(buttons):
touched = False
for finger, pos in fingers.items():
if rect.collidepoint(pos):
touched = True
highlight.append(touched)
# the same with list comprehensions
#highlight = [any(r.collidepoint(p) for _, p in fingers.items()) for _, r in enumerate(buttons)]
window.fill(0)
for rect, color, colorH, h in zip(buttons, colors, colorsH, highlight):
c = colorH if h else color
pygame.draw.rect(window, c, rect)

Any basic tutorial like this one shows how to do it, so it's not clear what you're having trouble with, since you didn't specify what issues you're having. This should work in your code though:
# goes at the top of the script:
image_to_draw = pygame.image.load('something.png')
# to draw the image:
WIN.blit(image_to_draw, (x, y, 50, 50))

How do I get my game to loop when calling the function from a button?

I'm trying to fix my game. When the game is over, it calls a crash() function. It gives the user the option to play again or quit. When calling my game_loop function in the "Play Again" button inside the crash() function, the game will not restart. Any suggestions? Thanks in advance.......................

You are setting the ship y to 2000 which is > 400 so it just goes back to crash. Change this to zero and it will work.

To make the rectangle permanent, you need to draw the rectangle in the application loop. The event occurs only once in a single frame. Add a variable clicked = False. Set the variable when the event occurs. And draw the rectangle dependent on the state of the variable:
clicked = False
while True:
screen.fill(background)
mouse = pygame.mouse.get_pos()
for ev in pygame.event.get():
if ev.type == pygame.QUIT:
pygame.quit()
if ev.type == pygame.MOUSEBUTTONDOWN:
if 10 <= mouse[0] <= 10 + 180 and 10 <= mouse[1] <= 10 + 190:
clicked = True
line_color = (212, 212, 255)
draw_line()
highlight()
if clicked:
pygame.draw.rect(screen,background,(10,10,180,190))
pygame.display.update()
Simplify your code:
Create a list of pygame.Rect objects for the rectangles
rect_list = [pygame.Rect(10, 10, 180, 190), ...]
Create a list for the stated of the fields
clicked_list = [0 for _ in rect_list]
Use collideponit to test if the mouse is on a rectangle:
for rect in rect_list:
if rect.collidepoint(mouse):
pygame.draw.rect(screen, hover_color, rect)
Use collidepoint to evaluate whether a field is clicked and to change the state of the field
if ev.type == pygame.MOUSEBUTTONDOWN:
for i, rect in enumerate(rect_list):
if rect.collidepoint(ev.pos):
clicked_list[i] = 1
Draw the field in a loop depending on its state:
for i, rect in enumerate(rect_list):
if clicked_list[i]:
pygame.draw.rect(screen,background,rect)
Complete code:
import pygame
pygame.init()
res = (600,600)
screen = pygame.display.set_mode(res)
pygame.display.set_caption("Tic Tac Toe")
background = (255,150,150)

Pygame changing movement speed of a blit [duplicate]

This question already has an answer here:
Why is my collision test always returning 'true' and why is the position of the rectangle of the image always wrong (0, 0)?

Closed 2 years ago.
Alright so I am trying to just code a simple pong game in python using pygame module and I keep running into an attribute error. I know similar questions have been asked before but I can't figure out the answer from those questions. I'd appreciate any help at all :).
so, the error i am getting in my code is
File "D:/Dev/Documents/Projects/Pong/pong.py", line 81, in <module>
ball.x += ball_speed_x
AttributeError: 'pygame.Surface' object has no attribute 'x'
my code is
import pygame, sys
pygame.init()
clock = pygame.time.Clock()
screen_width = 1280
screen_height = 960
screen = pygame.display.set_mode((screen_width,screen_height))
pygame.display.set_caption('game')
background = pygame.image.load('bg.png')
white = (255, 255, 255)
green = (51, 255, 51)
ball = pygame.image.load('ball.png')
paddle1 = pygame.Rect(screen_width - int(20), screen_height/int(2) - int(70), int(10), int(140))
paddle2 = pygame.Rect(int(10), screen_height/int(2) - int(70), int(10), int(140))
basicfont = pygame.font.SysFont(None, 48)
text = basicfont.render('Pong Game', True, green)
textrect = text.get_rect()
textrect.centerx = screen.get_rect().centerx
ball_speed_x = 7
ball_speed_y = 7
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
screen.fill(white)
screen.blit(background, (0, 0))
screen.blit(text, textrect)
pygame.draw.rect(screen, white, paddle1)
pygame.draw.rect(screen, white, paddle2)
pygame.draw.aaline(screen, green, (screen_width/2, 0), (screen_width/2, screen_height))
pygame.display.flip()
ball.x += ball_speed_x
ball.y += ball_speed_y
if ball.top <= 0 or ball.bottom >= screen_height:
ball_speed_y *= -1
if ball.left <= 0 or ball.right >= screen_width:
ball_speed_x *= -1
clock.tick(60)
Again, any help would be greatly appreciated and I am aware of other similar questions, I'm just new to this language and can't seem to figure this out. Thanks.
A pygame.Surface has no position. A Surface just contains the image.
If you want to draw the ball surface in the window, then you have to blit() the ball at a certain position.
You have to create a pygame.Surface and a pygame.Rect objecct:
ball = pygame.image.load('ball.png')
ball_rect = ball.get_rect(center = (screen_width // 2, screen_height // 2))
Then you can change the location of ball_rect and blit the ball to the screen Surface:
screen.blit(ball, ball_rect)
See the example:
import pygame, sys
pygame.init()
clock = pygame.time.Clock()
screen_width = 1280
screen_height = 960
screen = pygame.display.set_mode((screen_width,screen_height))
pygame.display.set_caption('game')
background = pygame.image.load('bg.png')
white = (255, 255, 255)
green = (51, 255, 51)
ball = pygame.image.load('ball.png')
ball_rect = ball.get_rect(center = (screen_width // 2, screen_height // 2))
paddle1 = pygame.Rect(screen_width - int(20), screen_height/int(2) - int(70), int(10), int(140))
paddle2 = pygame.Rect(int(10), screen_height/int(2) - int(70), int(10), int(140))
basicfont = pygame.font.SysFont(None, 48)
text = basicfont.render('Pong Game', True, green)
textrect = text.get_rect()
textrect.centerx = screen.get_rect().centerx
ball_speed_x = 7
ball_speed_y = 7
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
screen.fill(white)
screen.blit(background, (0, 0))
screen.blit(text, textrect)
pygame.draw.rect(screen, white, paddle1)
pygame.draw.rect(screen, white, paddle2)
pygame.draw.aaline(screen, green, (screen_width/2, 0), (screen_width/2, screen_height))
screen.blit(ball, ball_rect)
pygame.display.flip()
ball_rect.x += ball_speed_x
ball_rect.y += ball_speed_y
if ball_rect.top <= 0 or ball_rect.bottom >= screen_height:
ball_speed_y *= -1
if ball_rect.left <= 0 or ball_rect.right >= screen_width:
ball_speed_x *= -1
clock.tick(60)
