Is there a way I can display text on a pygame window using python?
I need to display a bunch of live information that updates and would rather not make an image for each character I need.
Can I blit text to the screen?
Yes. It is possible to draw text in pygame:
# initialize font; must be called after 'pygame.init()' to avoid 'Font not Initialized' error
myfont = pygame.font.SysFont("monospace", 15)
# render text
label = myfont.render("Some text!", 1, (255,255,0))
screen.blit(label, (100, 100))
You can use your own custom fonts by setting the font path using pygame.font.Font
pygame.font.Font(filename, size): return Font
example:
pygame.font.init()
font_path = "./fonts/newfont.ttf"
font_size = 32
fontObj = pygame.font.Font(font_path, font_size)
Then render the font using fontObj.render and blit to a surface as in veiset's answer above. :)
I have some code in my game that displays live score. It is in a function for quick access.
def texts(score):
font=pygame.font.Font(None,30)
scoretext=font.render("Score:"+str(score), 1,(255,255,255))
screen.blit(scoretext, (500, 457))
and I call it using this in my while loop:
texts(score)
There are 2 possibilities. In either case PyGame has to be initialized by pygame.init.
import pygame
pygame.init()
Use either the pygame.font module and create a pygame.font.SysFont or pygame.font.Font object. render() a pygame.Surface with the text and blit the Surface to the screen:
my_font = pygame.font.SysFont(None, 50)
text_surface = myfont.render("Hello world!", True, (255, 0, 0))
screen.blit(text_surface, (10, 10))
Or use the pygame.freetype module. Create a pygame.freetype.SysFont() or pygame.freetype.Font object. render() a pygame.Surface with the text or directly render_to() the text to the screen:
my_ft_font = pygame.freetype.SysFont('Times New Roman', 50)
my_ft_font.render_to(screen, (10, 10), "Hello world!", (255, 0, 0))

Minimal pygame.font example: repl.it/#Rabbid76/PyGame-Text
import pygame
pygame.init()
window = pygame.display.set_mode((500, 150))
clock = pygame.time.Clock()
font = pygame.font.SysFont(None, 100)
text = font.render('Hello World', True, (255, 0, 0))
background = pygame.Surface(window.get_size())
ts, w, h, c1, c2 = 50, *window.get_size(), (128, 128, 128), (64, 64, 64)
tiles = [((x*ts, y*ts, ts, ts), c1 if (x+y) % 2 == 0 else c2) for x in range((w+ts-1)//ts) for y in range((h+ts-1)//ts)]
for rect, color in tiles:
pygame.draw.rect(background, color, rect)
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
window.blit(background, (0, 0))
window.blit(text, text.get_rect(center = window.get_rect().center))
pygame.display.flip()
pygame.quit()

window = pygame.display.set_mode((500, 150))
clock = pygame.time.Clock()
ft_font = pygame.freetype.SysFont('Times New Roman', 80)
background = pygame.Surface(window.get_size())
ts, w, h, c1, c2 = 50, *window.get_size(), (128, 128, 128), (64, 64, 64)
tiles = [((x*ts, y*ts, ts, ts), c1 if (x+y) % 2 == 0 else c2) for x in range((w+ts-1)//ts) for y in range((h+ts-1)//ts)]
for rect, color in tiles:
pygame.draw.rect(background, color, rect)
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
window.blit(background, (0, 0))
text_rect = ft_font.get_rect('Hello World')
text_rect.center = window.get_rect().center
ft_font.render_to(window, text_rect.topleft, 'Hello World', (255, 0, 0))
pygame.display.flip()
pygame.quit()
exit()
I wrote a wrapper, that will cache text surfaces, only re-render when dirty. googlecode/ninmonkey/nin.text/demo/
I wrote a TextBox class. It can use many custom fonts relatively easily and specify colors.
I wanted to have text in several places on the screen, some of which would update such as lives, scores (of all players) high score, time passed and so on.
Firstly, I created a fonts folder in the project and loaded in the fonts I wanted to use. As an example, I had 'arcade.ttf' in my fots folder. When making an instance of the TextBox, I could specify that font using the fontlocation (optional) arg.
e.g.
self.game_over_text = TextBox("GAME OVER", 100, 80, 420, RED, 'fonts/arcade.ttf')
I found making the text and updating it each time "clunky" so my solution was an update_text method.
For example, updating the Player score:
self.score1_text.update_text(f'{self.p1.score}')
It could be refactored to accept a list of str, but it suited my needs for coding a version of "S

To use this in my Game class
from textbox import TextBox
and in the initialisation part of the game, something like this:
self.time_text = TextBox("Time Left: 100", 20, 20, 40)
self.cred_text = TextBox("created by Sean R.", 15, 600, 870)
self.score1_text = TextBox("0", 100, 40, 650)
self.score2_text = TextBox("0", 100, 660, 650)
self.lives1_text = TextBox("[P1] Lives: 3", 20, 40, 750)
self.lives2_text = TextBox("[P2] Lives: 3", 20, 660, 750)
self.game_over_text = TextBox("GAME OVER", 100, 80, 420, RED)
self.textbox_list = []
self.textbox_list.append(self.time_text)
self.textbox_list.append(self.cred_text)

self.textbox_list.append(self.score2_text)
self.textbox_list.append(self.lives1_text)
self.textbox_list.append(self.lives2_text)
so that when I want to draw all on the screen:
for txt in self.textbox_list:
txt.draw(screen)
In the update section of the game, I only update directly the boxes that have updated text using the update_text method- if there is nothing to be updated, the text stays the same.
I wrote a TextElement class to handle text placement. It's still has room for improvement. One thing to improve is to add fallback fonts using SysFont in case the font asset isn't available.

rendered_text = self.font.render(text, True, self.color)
if isinstance(coordinates, str):
coordinates = self.__calculate_alignment(rendered_text, coordinates)
self.surface.blit(rendered_text, coordinates)
return self
def __calculate_alignment(self, rendered_text, alignment):
# https://www.pygame.org/docs/ref/surface.html#pygame.Surface.get_rect
# Aligns rendered_text to the surface at the given alignment position

def __initialize_font(self):
return Font(os.path.join(
'assets', 'fonts', f'{self._font_name}.ttf'), self._size)
Here is how you can use it:
TextElement(self.screen, 80).write('Hello World!', 'midtop')
TextElement(self.screen).write('Hello World 2!', (250, 100))
# OR
text = TextElement(self.screen, 80)
text.size = 100
text.write('Bigger text!', (25, 50))
text.write('Bigger text!', 'midbottom')

This is a typing game in Python. Click the 'Play' button and the game is supposed to start. Random letters will fall down and each letter will disappear when you strike the corresponding key. However, it failed to begin when I click on the button. I think the problem must be related to the if statements if play_button.rect.collidepoint(mouse_x , mouse_y): in method check_play_button() of game_functions.py since if the if statement is removed, the stats.game_active is changed to True. On the other hand, if the if statement is removed, then click anywhere on the screen would change the value of stats.game_active to True. I am quite puzzled about the malfunction of the if statement. Please shed light on it.

Obviously I cannot test this but I think your problem is that you are not assigning position to your play_button.rect. By default, rect's positions values are (0, 0). I had the same problem a little while ago, so you are read some more details in answer to this question. One way to fix the problem - in button class make a getRect method:
class Button:
def getRect(self):
return pygame.Rect(x, y, width, height) # Since you will
#be using this rect for collision, enter the arguments accordingly
Then,
if play_button.getRect().collidepoint(mouse_x , mouse_y):
Other option is to directly assign position to the button rect but I prefer the first solution, its just a personal preference:
class Button():
def __init__(self, screen, msg):
self.rect.topleft = #your button position
If I create my UI in QT Designer (and import UI to the script), how can I hide and show tabs in my script?
class Tool(QMainWindow, uiTool.Ui_Tool):
def __init__(self):
super(Tool, self).__init__()
# SETUP UI
self.setupUi(self)
# self.tabWidget.removeTab() ???
There is no way to hide/show the tabs in a tab-widget, so you will need to remove and replace them instead.
Below is a demo script that shows how to do this. I have not attempted to keep track of the original indexes in this example - it just shows the basic usage of the methods involved:

It's been a while I'm searching all over the internet for that, but still couldn't get the answer... basically I have a QVBoxLayout which contains several frames - and each frame contains a button which function is to delete its parent frame. The main code was created using QT Designer and pyuic4. I wrote the two additional functions, one works perfectly ("createFrame") but I'm struggling with the "deleteFrame" one. the label inside the frame shows the index of that frame in the vert_layout "array". the problem I noted on my code is that, using it that way, I can only delete the last frame added. So, can someone help me with this issue?
please see my code below:

All you are currently doing is deleting the self.frame widget each time.
So only the last created one gets deleted. And not the one you actually click on.
Modified your code for what you need. Hope it helps you understand.
