# Support AI construction of buildings.

Pass terrain passability data to AI scripts.
Expand pathfinder passability data to 16 bits per tile, to allow more
classes.
Support 16-bit ints in serializer.
Partially support JS typed arrays.
Allow foundations to be placed on top of units (fixes #499).
Stop farms and fishes blocking movement (fixes #534).
Add obstruction flags to allow finer control over what they block.
Associate entity IDs with obstruction shapes, to allow finding colliding
entities.
Support moving to the edge of a target entity with inactive obstruction.
Support foundation entities in AI.
Support playing as non-hele civs.
