在pygame中渲染多行文本 [英] Rendering text with multiple lines in pygame

问题描述

我正在尝试制作游戏，并且正在尝试渲染大量文本.当文本呈现时，其余文本会离开屏幕.有没有什么简单的方法可以让文本转到pygame窗口的下一行?

I am trying to make a game and I am trying to render a lot of text. When the text renders, the rest of the text goes off the screen. Is there any easy way to make the text go to the next line of the pygame window?

helpT = sys_font.render \
                ("This game is a combination of all of the trends\n of 2016. When you press 'Start Game,' a menu will pop up. In order to beat the game, you must get a perfect score on every single one of these games.",0,(hecolor))
        screen.blit(helpT,(0, 0))

推荐答案

正如我在评论中所说；您必须单独呈现每个单词并计算文本的宽度是否扩展了表面(或屏幕)的宽度.举个例子:

As I said in the comments; you have to render each word separately and calculate if the width of the text extends the width of the surface (or screen). Here's an example:

import pygame
pygame.init()


SIZE = WIDTH, HEIGHT = (1024, 720)
FPS = 30
screen = pygame.display.set_mode(SIZE, pygame.RESIZABLE)
clock = pygame.time.Clock()


def blit_text(surface, text, pos, font, color=pygame.Color('black')):
    words = [word.split(' ') for word in text.splitlines()]  # 2D array where each row is a list of words.
    space = font.size(' ')[0]  # The width of a space.
    max_width, max_height = surface.get_size()
    x, y = pos
    for line in words:
        for word in line:
            word_surface = font.render(word, 0, color)
            word_width, word_height = word_surface.get_size()
            if x + word_width >= max_width:
                x = pos[0]  # Reset the x.
                y += word_height  # Start on new row.
            surface.blit(word_surface, (x, y))
            x += word_width + space
        x = pos[0]  # Reset the x.
        y += word_height  # Start on new row.


text = "This is a really long sentence with a couple of breaks.\nSometimes it will break even if there isn't a break " \
       "in the sentence, but that's because the text is too long to fit the screen.\nIt can look strange sometimes.\n" \
       "This function doesn't check if the text is too high to fit on the height of the surface though, so sometimes " \
       "text will disappear underneath the surface"
font = pygame.font.SysFont('Arial', 64)

while True:

    dt = clock.tick(FPS) / 1000

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            quit()

    screen.fill(pygame.Color('white'))
    blit_text(screen, text, (20, 20), font)
    pygame.display.update()

结果
