将keypressed与char进行比较

Posted 2021-04-18

我想用pygame在python中制作某种打字游戏。因此，如果按下的按键字符与单词中的字符相同，则应该返回true ...有没有办法在python中执行此操作？

例如：单词是“cat”，如果用户按下键'c'，则返回true ...依此类推其余字符。

here's my main.py file

from time import sleep
import pygame
import random
import winsound
from words import Words

BLACK = (  0,   0,   0)
WHITE = (255, 255, 255)
BLUE =  (  0,   0, 255)
GREEN = (  0, 255,   0)
RED =   (255,   0,   0)

pygame.init()

SCREEN_WIDTH = 800
SCREEN_HEIGHT = 600

done = False

clock = pygame.time.Clock()

screen = pygame.display.set_mode((SCREEN_WIDTH,SCREEN_HEIGHT))

w1 = Words(screen) #making a single word (for now) to see if typing works

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True


    screen.fill(WHITE)
    w1.draw()

    #attempting to write code here to compare word and user input



    pygame.display.flip()
    clock.tick(60)


pygame.init()
exit()

here's my words.py file

from random_words import RandomWords
import pygame
import random
from queue import *

rw = RandomWords()

class Words():
    def __init__(self, screen):
        self.screen = screen
        self.x_point = 400
        self.y_point = 400
        self.word = rw.random_word() #generates a random word
        self.queue = Queue() #was hoping to use the queue so that if the user types the char correctly in the right order, then the letter would change color or something (but that's further down the line)
        for c in self.word: #iterate through randomized word.. 
            self.queue.put(c) #add each char in randomized word to queue, for typing reasons

    def getY(self):
        return self.y_point

    def draw(self):
        #creates a new object
        myfont = pygame.font.SysFont('Comic Sans MS' ,30)
        #creates a new surface with text drawn on it
        textsurface = myfont.render(self.word, False, (0,0,0))

        self.screen.blit(textsurface,(self.x_point,self.y_point))

答案

事件KEYDOWN有event.unicode，event.key，event.mod

你可以比较

if event.type == pygame.KEYDOWN:
    if event.unicode == "a":

甚至

if event.type == pygame.KEYDOWN:
    if event.unicode.lower() == "a":

检查"a"和"A"

用词检查char

if event.type == pygame.KEYDOWN:  
    if event.unicode.lower() in your_word.lower():

---

示例代码使用event.unicode使用按下的键呈现文本。

顺便说一句：这不是一些Entry小部件，所以当你按backspace时它不会删除字符。
