       Milestone:  unspecified       |  Component:  other
         Version:  3.1 beta11        |   Keywords:  trucks paths structures

 Example:

 Assume that there is a field without any obstacles, with a subfield 4 x 4:

 a4  b4  c4  d4

 a3  b3  c3  d3

 a2  b2  c2  d2

 a1  b1  c1  d1

 The truck is on the left lower side of defensive structures at a4, b3, c2,
 d1. Order the truck to build a defensive structure at c3. Sometimes, the
 truck chooses the shortest path to build the structure at c3 after
 commming to b2. More often, the truck goes to the upper right side of the
 map and builds the structure at c3.

 There is a similar behaviour when c3 structure is damaged and the truck
 goes to repair the structure.

 This type of behaviour is easier to spot when diagonally placed structures
 are much longer than in this example.

 I expected trucks to choose the shortest path and stay at the same side of
 diagonal for building or repairing structures that are diagonally
 accessible.
 Does orientation of the truck influence algorithm for choosing path?
 Maybe allowing trucks to move backward would result with more the shortest
 paths and staying on friendly side of the diagonal instead of going to
 unfriendly side.
