所以我有这个功能可以将文本闪烁到屏幕上:
def text_speech(font : str ,size : int,text : str,color,x,y, bold : bool):
SCREEN = width, height = 900, 600
font = pygame.font.Font(font,size)
font.set_bold(bold)
text = font.render(text, True, color)
textRect = text.get_rect()
textRect.center = (x,y)
screen.blit(text,textRect)

如果我有
screen.fill((0,0,0))
text_speech('arialnarrow.ttf', 30, 'Hello', (255,255,255),
width/2, height/2, False)

它在带有白色文本的黑色屏幕上打印“你好”。如果玩家将鼠标悬停在此文本上,我如何使文本气泡看起来像这样:
我只想要一个绿色背景的文本,上面写着“点击确认”。任何人都知道如何做到这一点。我很抱歉,我对 Pygame 有点陌生。
的第四个参数font.render是可选的文本背景颜色:
color = (255, 255, 255)
background = (0, 255, 0)
text = font.render(text, True, color, background)

另一种选择是将文本渲染到表面并将表面格式转换为每像素 alpha 格式 ( convert_alpha):
textSurf = font.render(text, True, color).convert_alpha()
textSize = textSurf.get_size()

创建一个双倍大小的新曲面:
bubbleSurf = pygame.Surface((textSize[0]*2., textSize[1]*2))
bubbleRect = bubbleSurf.get_rect()

看例子:
import pygame
import pygame.font
pygame.init()
width, height = 400, 300
screen = pygame.display.set_mode((width, height))
clock = pygame.time.Clock()
textRect = pygame.Rect(0, 0, 0, 0)
def text_speech(font : str, size : int, text : str,color,background,x,y, bold : bool, bubble: bool):
global textRect
font = pygame.font.SysFont(None, 40)
#font = pygame.font.Font(font,size)
font.set_bold(bold)
textSurf = font.render(text, True, color).convert_alpha()
if bubble:
textSize = textSurf.get_size()
bubbleSurf = pygame.Surface((textSize[0]*2., textSize[1]*2))
textRect = bubbleSurf.get_rect()
bubbleSurf.fill(background)
bubbleSurf.blit(textSurf, textSurf.get_rect(center = textRect.center))
textRect.center = (x,y)
screen.blit(bubbleSurf, textRect)
else:
textRect = textSurf.get_rect()
textRect.center = (x,y)
screen.blit(textSurf, textRect)
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
hover = textRect.collidepoint(pygame.mouse.get_pos())
screen.fill((0,0,0))
text_speech('arialnarrow.ttf', 30, 'Hello', (255,255,255), (0, 128, 0),
(width/2), (height/2), False, hover)
pygame.display.flip()
