Python显示字体和颜色的文本？

Question

有没有办法可以使用python在pygame窗口上显示文本？

我需要显示一堆更新的实时信息,而不是为我需要的每个角色制作一个图像.

我可以在屏幕上显示文字吗？

Answer 1

是.可以在pygame中绘制文本:

# 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))

Answer 2

您可以使用pygame.font.Font设置字体路径来使用自己的自定义字体

pygame.font.Font(filename, size): return Font

例:

pygame.font.init()
font_path = "./fonts/newfont.ttf"
font_size = 32
fontObj = pygame.font.Font(font_path, font_size)

然后使用fontObj.render渲染字体并将blit渲染到曲面,如上面的veiset答案.:)

Answer 3

我的游戏中有一些显示实时得分的代码.它具有快速访问功能.

def texts(score):
   font=pygame.font.Font(None,30)
   scoretext=font.render("Score:"+str(score), 1,(255,255,255))
   screen.blit(scoretext, (500, 457))

我在while循环中使用它来调用它:

texts(score)

Answer 4

有两种可能性。无论哪种情况，PyGame 都必须由 初始化pygame.init。

import pygame
pygame.init()

使用任一pygame.font模块并创建一个pygame.font.SysFontorpygame.font.Font对象。render()apygame.Surface包含文本和blit屏幕表面：

my_font = pygame.font.SysFont(None, 50)
text_surface = myfont.render("Hello world!", True, (255, 0, 0))
screen.blit(text_surface, (10, 10))

或者使用该pygame.freetype模块。创建一个pygame.freetype.SysFont()或pygame.freetype.Font对象。render()apygame.Surface与文本或直接将render_to()文本显示到屏幕上：

my_ft_font = pygame.freetype.SysFont('Times New Roman', 50)
my_ft_font.render_to(screen, (10, 10), "Hello world!", (255, 0, 0))
