python:typeerror:需要整数..卡住了

尝试运行时接收到类型错误:

File "/home/XX/PycharmProjects/rogue_like/venv/lib64/python3.7/site-packages/tcod/libtcodpy.py", line 1236, in console_put_char
    lib.TCOD_console_put_char(_console(con), x, y, _int(c), flag)
TypeError: an integer is required

Class Object:

    def __init__(self, x, y, char, color):
        self.x = x
        self.y = y
        self.char = char
        self.color = color

    def draw(self):
        libtcod.console_set_default_foreground(con, self.color)
        libtcod.console_put_char(con, self.x, self.y, self.char, libtcod.BKGND_NONE)

# later...

SCREEN_WIDTH = 80
SCREEN_HEIGHT = 50
player = Object(SCREEN_WIDTH/2, SCREEN_HEIGHT/2, '@', libtcod.yellow)

在一个类似流氓的教程之后,遇到了这个问题。试图通过将“@”改为数字等方式传递整数。试着把它交给 int(self.char) 还有其他的选择,但似乎是碰壁了。

任何帮助都很好!试图包含相关的代码,如果有其他的,请告诉我。

编辑:
