好吧,我只是想先使其旋转,然后再缩放,然后一旦我确定旋转缩放应该很容易就可以了。对于我的一生,我似乎无法正常工作。这是一个简单的类,我希望对象随时间旋转以及在x方向上进行转换。转换工作正常,但我无法旋转。
class Puff(pygame.sprite.Sprite):
def __init__(self, screen):
pygame.sprite.Sprite.__init__(self)
self.screen = screen
try:
self.imagePuff = pygame.image.load(os.path.join("Images","puff.tga")).convert()
except:
raise UserWarning, "Unable to find Puff image"
self.imagePuff.set_colorkey((0,0,255))
self.image = self.imagePuff
self.rect = self.image.get_rect()
self.x = self.screen.get_width()/3
self.y = self.screen.get_height()/3+10
self.rect.center = (self.x, self.y)
self.lifespan = 60
self.speed = 1
self.count = 0
self.angle = 0
def update(self):
self.calcPos()
self.rect.center = self.x, self.y
self.transform()
if self.count > self.lifespan:
self.kill()
def calcPos(self):
self.x -= 5
self.y = self.y
def transform(self):
self.count += 1.1
self.angle += self.count*25
self.newTrans = pygame.transform.scale(self.copyImage, (400,400))
self.newRect = self.newTrans.get_rect()
self.newRect.center = self.rect.center
