Pygame creates a font object through the pygame.font module to achieve the purpose of drawing text.
The common methods of this module are as follows:
| Name | Description |
|---|---|
pygame.font.init() |
Initialize the font module |
##pygame.font.quit()
| Cancel initialization of the font module|
|
|
|
|
|

module provides two methods for creating font (Font) objects, namely:
(Load font files from the system to create font objects )
(Create font object through file path)
pygame.font.SysFont(name, size, bold=False, italic=False)
Parameter description is as follows:
print("获取系统中所有可用字体",pygame.font.get_fonts())
my_font = pygame.font.SysFont(['方正粗黑宋简体','microsoftsansserif'],50)The above method will give priority to "Founder Bold Black Song Simplified".
font.Font()
When we want to introduce a cooler font into the game but it does not exist in the system, we can An alternative method is to load font files externally to draw text. The syntax format is as follows: my_font = pygame.font.Font(filename, size)
f = pygame.font.Font('C:/Users/Administrator/Desktop/willhar_.ttf',50)
This function creates a rendered text Surface object | pygame.font.Font.size() |
This function returns the size required to render text. The return value is a One-tuple (width,height) | ##pygame.font.Font.set_underline() |
| pygame.font.Font.get_underline() |
| pygame.font.Font.set_bold() |
| ##pygame.font.Font.get_bold() |
| pygame.font.Font.set_italic() |
| pygame.font.Font.metrics() |
| pygame.font.Font.get_italic() |
| pygame.font .Font.get_linesize() |
| pygame.font.Font.get_height() |
| Get the distance from the top of the font to the baseline |
| Get the distance from the bottom of the font to the baseline |
<blockquote><p>使用上述方法，我们可以非常方便地对字体进行渲染，或者获取字体的相关信息，比如字体的高度、是否是粗体、斜体等信息。</p></blockquote><p>上述方法中使用最多要数第一个方法，它是绘制文本内容的关键方法，其语法格式如下：</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:py;">render(text, antialias, color, background=None)</pre><div class="contentsignin">Copy after login</div></div><p>参数说明如下:</p><ul class=" list-paddingleft-2"><li><p><code>text : 要绘制的文本内容
下面看一组简单的示例： import sys
import pygame
# 初始化
pygame.init()
screen = pygame.display.set_mode((600, 400))
# 填充主窗口的背景颜色
screen.fill((20, 90, 50))
# 设置窗口标题
pygame.display.set_caption('Python自学网')
# 字体文件路径 C:/Windows/Fonts/simhei.ttf
f = pygame.font.Font('C:/Windows/Fonts/simhei.ttf', 50)
# render(text, antialias, color, background=None) -> Surface
text = f.render("网址：python.net", True, (255, 0, 0), (255, 255, 255))
# 获得显示对象的 rect区域大小
textRect = text.get_rect()
# 设置显示对象居中
textRect.center = (300, 200)
screen.blit(text, textRect)
while True:
# 循环获取事件，监听事件
for event in pygame.event.get():
# 判断用户是否点了关闭按钮
if event.type == pygame.QUIT:
# 卸载所有pygame模块
pygame.quit()
# 终止程序
sys.exit()
pygame.display.flip() # 更新屏幕内容Copy after login 除了使用上述方法之外，Pygame 为了增强字体模块的功能，在新的版本中又加入了另外一个字体模块，它就是 Freetype 模块。该模块属于 Pygame 的高级模块， 它能够完全可以取代 Font 模块，并且在 Font 模块的基础上又添加了许多新功能，比如调整字符间距离，字体垂直模式以及逆时针旋转文本等（详情可阅读官方文档）。 如果想 Freetype 模块，必须使用以下方式导包： import pygame.freetype Copy after login 下面使用 Freetype 模块来绘制文本内容，代码如下： import sys, pygame
import pygame.freetype
pygame.init()
# 设置位置变量
pos = [180, 50]
# 设置颜色变量
GOLD = 255, 251, 0
BLACK = 0, 0, 0
screen = pygame.display.set_mode((600, 400))
pygame.display.set_caption("Python自学网")
f1 = pygame.freetype.Font("C:/Users/Administrator/Desktop/willhar_.ttf", 45)
# 注意，这里使用render_to() 来绘制文本内容，与render 相比，该方法无返回值
# 参数说明：
# pos 绘制文本开始的位置，fgcolor表示前景色，bgcolor表示背景色，rotation表示文本旋转的角度
freeRect = f1.render_to(screen, pos, "I love python.net", fgcolor=GOLD, bgcolor=BLACK, rotation=35)
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
pygame.display.update()Copy after login The above is the detailed content of Python's Pygame Font module - how to use text and fonts?. For more information, please follow other related articles on the PHP Chinese website!
