OBJFileLoader 오류

Question

OBJFILELOADER.py 파일의 링크 (https://www.pygame.org/wiki/OBJFileLoader)에 오류가 있습니다. 나는 그러나 나는 인상 ValueError를 일을 변경 시도 OBJ 등 OBJ = (파일 이름)을 사용

을하지만 여전히 오류가 많이있다, python3 버전 오류로 python2가 있다고 생각.

블렌더에서 .obj 파일을 가져 왔는데, 그게 문제라고 생각하지 않습니다.

Traceback (most recent call last):

    return self._finalCall(*args, **named) 
TypeError: 'NoneType' object is not callable 

During handling of the above exception, another exception occurred:

Answer 1

당신은 단지 변수 obj에 파일 이름을 지정하는 것 - 사람은 Python3

오류 나에게 정확한 objfileloader을 알 수 있습니다. 파이썬 포트에 linked answer 3 확인 스크립트를

obj = OBJ(filename) 

아웃 :

대신 당신은 OBJ 클래스의 인스턴스를 생성하고 파일/경로 이름을 전달해야합니다.
