Python + Pyglet Cocos2D：TypeError：“类”对象不可调用

Question

I've been working on a tiled map renderer, and I've tried to make a seperate Class in another file. I get this error message:

Type Error: 'renderer' object is not callable

Here's the render.py file:

import pyglet, json
from pyglet.window import key
from pyglet.gl import *
from ConfigParser import SafeConfigParser
from cocos.layer import *
from cocos.batch import *
from cocos.sprite import Sprite

class renderer( Layer ):
    def __init__(self, mapname):
        super( renderer, self ).__init__()
        parser = SafeConfigParser()
        try:
            world = parser.read('maps/'+mapname+'.txt')
            print world
        except IOError:
            print("No world file!")
            return
        layer = json.loads(parser.get('layer1', 'map'))
        tiletype = parser.get('type', 'tile')
        print tiletype
        tilesize = 64

        for x in range(0, len(layer)):
            for y in range(0, len(layer[x])):
                self.spr = Sprite("image/tiles/"+tiletype+"/"+str(layer[x][y])+".png")
                self.spr.position = ((x+1)*tilesize, (y+1)*tilesize)
                self.add(self.spr)

And this is the piece of code I call it with:

from other.render import renderer

world = renderer('buildnew')
world()

File Structure:

game/main.py
game/other/render.py

What am I doing wrong?

Answer 1

world = renderer('buildnew')
world()

First you make an instance of the renderer class and store it to world. But then you write world() , which is wrong cause this object is not callable. If you want to make world a callable object, you should implement the __call__ method in the renderer class.
