我有这个功能:
def imgload(dir, file, convert=2, colorkey=None):
img = pygame.image.load(os.path.join(dir, file))
if convert == 1:
img.convert()
elif convert == 2:
img.convert_alpha()
if colorkey is not None:
img.set_colorkey(colorkey)
return img
那么我有
logo = imgload("Big_Images", "logo.png", 1, (0, 0, 0))
和一个类(不要看缩进,我无法理解它;它在实际代码中是正确的)
class Intro(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.image = logo
self.rect = self.image.get_rect()
self.rect.centerx = round(WINDOW_WIDTH / 2)
self.rect.centery = round(WINDOW_HEIGHT / 2)
self.transparency = 255
def update(self):
global game_state
if self.transparency > 0:
self.transparency -= 1
self.image.set_alpha(self.transparency)
else:
game_state = "home"
游戏循环中的绘制函数(while):
if game_state == "intro": WIN.fill(GRAY) all_intro_sprites.draw(WIN) all_intro_sprites.update()
奇怪的是,当我这样做时,代码工作正常
logo= pygame.image.load(os.path.join("Big_Images", "logo.png").convert()
convert()
和 convert_alpha()
不会就地转换图像。这些函数创建并返回具有所需像素格式的表面的新副本。您必须将返回值分配给img
。例如:
img = img.convert_alpha()
修正功能
imgload
:
def imgload(dir, file, convert=2, colorkey=None):
img = pygame.image.load(os.path.join(dir, file))
if convert == 1:
img = img.convert()
elif convert == 2:
img = img.convert_alpha()
if colorkey is not None:
img.set_colorkey(colorkey)
return img
