Here's the code (I've added some debug printing):
typedef struct {
PyObject base;
int width, height;
PyObject *walls_dict;
PyObject *distances;
PyObject *vector_dict;
} VectorField;
static int vector_field_init(VectorField *self, PyObject *args, PyObject *kwds) {
PyObject *walls;
int sprite_size, height, width;
if (!PyArg_ParseTuple(args, "Oiii", &walls, &sprite_size, &height, &width)) {
return -1;
}
if (sprite_size && height && width) {
SPRITE_SIZE = sprite_size;
self->height = height;
self->width = width;
} else {
return -1;
}
PyObject *sprite_list = PyObject_GetAttrString(walls, "sprite_list");
PyObject *temp_walls_dict = PyDict_New();
PyObject *infinity = Py_BuildValue("i", std::numeric_limits<int>::max());
for (int i = 0; i < PyList_Size(sprite_list); i++) {
std::cout << "iteration " << i << "\n";
PyObject *item = PyList_GetItem(sprite_list, i);
PyObject_Print(item, stdout, 0);
std::cout << "\n";
std::cout << "attr check " << PyObject_HasAttrString(item, "position") << "\n";
PyObject *sprite_position = PyObject_GetAttrString(item, "position");
PyObject_Print(sprite_position, stdout, 0);
std::cout << "\n";
PyDict_SetItem(temp_walls_dict, pixel_to_tile_pos(NULL, sprite_position), infinity);
}
self->walls_dict = temp_walls_dict;
/* Return success */
std::cout << "r" << "\n";
return 0;
}
And the console output:
iteration 0
<arcade.sprite.Sprite object at 0x000002551F03B1F0>
attr check 1
(84.0, 84.0)
iteration 1
<arcade.sprite.Sprite object at 0x000002551F03B1C0>
attr check 0
(140.0, 84.0)
The attribute check should be returning 1 for every single iteration, but its not
formal tartan
