参数将值传递给我在 python/Pygame 中的类

Question

I have a class in Python that will be for the spawning of NPC's in a small space. I want to pass the information (such as the location for their image/sprite, their co-ordinates where they'll spawn, etc.) into the class:

class NPC(object):
        def __init__(self, img, x, y):
                self.image = pygame.image.load(img).convert_alpha()
                self.x = x
                self.y = y

I want the values img, x and y to be passed in but I cannot think of a suitable method of doing so, as the init function for some reason cannot be called.

I feel that the solution is staring me right in the face but I don't know how to get to it.

Answer 1

Not sure why you say that the init cannot be called? To run the built in function init you just write:

joe = NPC(joe_image, joe_x, joe_y)

If joe already exists and you want to respawn him, just copy init as another function:

def respawn(self,(self, x, y):
            self.x = x
            self.y = y

and call:

joe.respawn(joe_x, joe_y)

[I'm assuming you don't need to change his image here]
