示例1: hit_test

def hit_test(self, position, vector, max_distance=8):
""" Line of sight search from current position. If a block is
intersected it is returned, along with the block previously in the line
of sight. If no block is found, return None, None.
Parameters
----------
position : tuple of len 3
The (x, y, z) position to check visibility from.
vector : tuple of len 3
The line of sight vector.
max_distance : int
How many blocks away to search for a hit.
