尝试获取纹理区域时出现分段错误

Question

我创建了一个简单的函数，从给定的图像返回一个纹理区域：

from kivy.core.image import Image


def get_figure_texture(figure: Figure, img_path: str):
image = Image(img_path).texture
figures = {
    'white': {
        'king': (0, 0),
        'queen': (64, 0),
        'rook': (128, 0),
        'knight': (192, 0),
        'bishop': (256, 0),
        'pawn': (320, 0)
    },
    'black': {
        'king': (0, 64),
        'queen': (64, 64),
        'rook': (128, 64),
        'knight': (192, 64),
        'bishop': (256, 64),
        'pawn': (320, 64)
    }
}
offset = figures[figure.color_name][figure.name]

return image.texture.get_region(offset[0], offset[1], 64, 64)

然后，我想创建一个纹理：

 figure = Figure
 figure.name = 'king'
 figure.color_name = 'white'
 figure.texture - get_figure_texture(figure, 'res/figures.png')

当Kivy尝试从给定路径创建图像时，我会在日志中得到这个：

[INFO   ] [Logger      ] Record log in

图像是384 x 128，我提供的路径是正确的，因为对于其他路径我得到错误：AttributeError: 'NoneType' object has no attribute 'tell'。

Answer 1

1. Kivy的pygame后端已被弃用，请尝试使用sdl2。
2. 如果这是您实际代码的良好表示，请尝试在顶部添加from kivy.core.window import Window。
