class src.canns.task.MovementCostGrid

get_cell_index(pos)

Get the geodesic index of the grid cell containing the given position.

This method is JAX-compatible and can be used inside jitted functions.

Parameters:

pos (collections.abc.Sequence[float]) – (x, y) coordinates of the position.

Returns:

Index of the grid cell in the accessible_indices array, or -1 if the position is out of bounds or in an impassable cell.

Return type:

int

Note

Returns -1 (instead of None) for JAX compatibility. The caller should check for negative values to detect invalid positions.
