如何在pygame中将f字符串blit到if语句？

Question

我正在做我的第一个项目，这是pygame中的一个骰子游戏，你按y键掷骰子，你和电脑对决，谁掷得高谁就赢。我把整个游戏都设置好了，但是我很难向谁赢的人显示文本，比如。。。 你赢了！对手掷3分。我可以在控制台中显示文本，但不能在pygame窗口中显示，并且不知道如何将其输入

参考代码

import pygame
import random
import os
import os.path

WIDTH = 750
HEIGHT = 750
FPS = 60
QUARTER_WIDTH = WIDTH // 4
MIDDLE_HEIGHT = HEIGHT // 2
white = (255, 255, 255)



pygame.init()
pygame.font.init()
window = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Dice Game")

# Fonts and Text
title_font = pygame.font.SysFont("comicsans", 70)
title_label = title_font.render("Would You like to roll? Y/N", 1, (255, 255, 255))


# Load images
dice1 = pygame.image.load(os.path.join("assets", "dice_1.png"))
dice2 = pygame.image.load(os.path.join("assets", "dice_2.png"))
dice3 = pygame.image.load(os.path.join("assets", "dice_3.png"))
dice4 = pygame.image.load(os.path.join("assets", "dice_4.png"))
dice5 = pygame.image.load(os.path.join("assets", "dice_5.png"))
dice6 = pygame.image.load(os.path.join("assets", "dice_6.png"))

# Indexed list to reference all the faces
all_dice = [None, dice1, dice2, dice3, dice4, dice5, dice6]
pygame.display.set_icon(dice6)

# Game Background
background = pygame.transform.scale(pygame.image.load(os.path.join("assets", "dice_board.png")), (WIDTH, HEIGHT))


### Function to perform the random parts of the game
def rollDice():
    """ Generate the two random numbers, one for the Player and Opponent """
    player_roll = random.randint(1, 6)
    opponent_roll = random.randint(1, 6)

    return player_roll, opponent_roll


### Main Loop
clock = pygame.time.Clock()
running = True
player_face = None  # No dice before first roll
player_roll = 0
opponent_face = None  # No dice before first roll
player_roll = 0

while running:

    # handle user input
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_y:
                player_roll, opponent_roll = rollDice()
                player_face = all_dice[player_roll]
                opponent_face = all_dice[opponent_roll]

                # Debug prints
                font = pygame.font.Font("freesansbold.ttf", 32)
                text1 = font.render(f'opponent won. They rolled a {opponent_roll}', 1, white)
                text2 = font.render(f'You win! They rolled a {opponent_roll}', 1, white)
                text3 = font.render('Tied!', 1, white)
                textRect1 = text1.get_rect()
                textRect2 = text2.get_rect()
                textRect3 = text3.get_rect()
                textRect1.center = (WIDTH // 2, HEIGHT // 2)
                textRect2.center = (WIDTH // 2, HEIGHT // 2)
                textRect3.center = (WIDTH // 2, HEIGHT // 2)
                if opponent_roll > player_roll:
                    print(f"opponent won. They rolled a {opponent_roll}")
                    window.blit(text1, textRect1)
                elif opponent_roll < player_roll:
                    print(f"You win! They rolled a {opponent_roll}")
                    window.blit(text2, textRect2)
                elif opponent_roll == player_roll:
                    print("tied!")
                    window.blit(text3, textRect3)

    # Reapint the screen
    window.blit(background, (0, 0))
    window.blit(title_label, (WIDTH // 2 - title_label.get_width() // 2, 250))

    # Paint the dice faces
    if (player_face != None):
        window.blit(player_face, (QUARTER_WIDTH, MIDDLE_HEIGHT))
    if (opponent_face != None):
        window.blit(opponent_face, (3 * QUARTER_WIDTH, MIDDLE_HEIGHT))

    # flush display changes
    pygame.display.flip()

    # Constrain FPS
    clock.tick(FPS)

pygame.quit()

要呈现tetx，需要使用pygame.font

https://www.pygame.org/docs/ref/font.html

基本上，您必须创建位图字体，使用该字体将文本渲染到曲面，然后blit曲面

pygame.font.init() 
myfont = pygame.font.SysFont('Arial', 8)
helloWorld = myfont.render('Hello World', False, (0, 0, 0))
screen.blit(helloWorld,(20,30))
