我正在使用pygame模块在python中制作游戏,我希望将一个特定的变量从一个类继承到另一个类,但不知道如何做。我已经尝试过super(),但是它没有用,但是,作为新手,我可能只是说我做错了,所以请不要小看它是否可行。
我也在下面的代码中列出了我希望继承哪个变量。
这是我下面的相关代码:
我要继承自的类:
class player():
def __init__(self, x, y, width, height, walkCount):
self.x = x
self.y = y
self.width = width
self.height = height
self.vel = 15
self.lastDirection = "right" or "left" or "up" or "down" #<--- variable I want to inherit
self.walkCount = walkCount
def drawCharacter(self, window):
dest = (self.x, self.y)
if self.walkCount + 1 >= 30:
self.walkCount = 0
if self.lastDirection == "left":
window.blit(protagL[0], dest)
elif self.lastDirection == "right":
window.blit(protagR[0], dest)
elif self.lastDirection == "up":
window.blit(protagU[0], dest)
elif self.lastDirection == "down":
window.blit(protagD[0], dest)
我要接收继承的类:
class projectile(player):
def __init__(self, x, y, direction, travelCount):
self.x = x
self.y = y
self.direction = direction
self.vel = 20 * direction
self.travelCount = travelCount
def drawBullet(self, window):
dest = (self.x, self.y)
if self.travelCount + 1 >= 15:
self.walkCount = 0
if lastDirection == "right" or "left": # <--- I Want to call lastDirection variable here
if self.travelCount < 15:
window.blit(bulletsP[self.travelCount//3], dest) #dest)
self.travelCount += 1
self.x += self.vel
非常感谢您的帮助。

您必须调用基类的构造函数。参见super()
:
class projectile(player):
def __init__(self, x, y, direction, travelCount):
super().__init__(x, y, 10, 10, travelCount)
# [...]
请注意,在您的示例中,宽度和高度的参数不清楚,因此我示例性地使用了(10,10)。
