这是改编自我写的一些非常古老的代码：def renderTextCenteredAt(text, font, colour, x, y, screen, allowed_width):
# first, split the text into words
words = text.split()
# now, construct lines out of these words
lines = []
while len(words) > 0:
# get as many words as will fit within allowed_width
line_words = []
while len(words) > 0:
line_words.append(words.pop(0))
fw, fh = font.size(' '.join(line_words + words[:1]))
if fw > allowed_width:
break
# add a line consisting of those words
line = ' '.join(line_words)
lines.append(line)
# now we've split our text into lines that fit into the width, actually
# render them
# we'll render each line below the last, so we need to keep track of
# the culmative height of the lines we've rendered so far
y_offset = 0
for line in lines:
fw, fh = font.size(line)
# (tx, ty) is the top-left of the font surface
tx = x - fw / 2
ty = y + y_offset
font_surface = font.render(line, True, colour)
screen.blit(font_surface, (tx, ty))
y_offset += fh
基本算法是将文本拆分为单词，然后逐字逐行逐字检查结果宽度，并在超出宽度时拆分为新行。在
由于您可以查询呈现文本的宽度，所以您可以确定在何处呈现文本以使其居中。在 |
