'pygame - How to display text with font & color?
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?
Solution 1:[1]
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()
exit()
Minimal pygame.freetype example: repl.it/@Rabbid76/PyGame-FreeTypeText
import pygame
import pygame.freetype
pygame.init()
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/
Solution 6:[6]
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.score1_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.
