All IG code should use the interface of LocatedEntity when dealing
with any entity, rather than sometimes requiring Entity. Add virtual
functions to the interface where required, and modify all other interfaces
to stop them using Entity. This makes the code way cleaner, and much better
de-coupled.
The Link reference provided is the object allowing direct communication
back to the external source of the operation. This allows us to handle
things more cleanly in some cases.
* rulesets/Python_API.cpp: Expose wfmath's epsilon as a const value
to python.
* rulesets/Py_Point3D.cpp: Expose isValid() method on WFMath::Point<3>
to python.
* rulesets/Entity.cpp: Call decRef() on parent from the destructor
so that entities removed from the world can still have a reference
to their parent safely.
* rulesets/BaseMind.cpp, rulesets/MemMap.cpp, tests/distancetest.cpp:
Make sure parent is 0 before deleting, as reference counting is not
implemented in the mind yet.
* modules/Location.cpp, modules/Location.h: Add new function for
usefully calculating the distance vector of another entity.
* tests/distancetest.cpp: Update test to check new distance
function.
* rulesets/Python_API.cpp: Make the new distance vector function
available to python rather than the relative postion function.
* rulesets/basic/mind/Knowledge.py, rulesets/basic/mind/NPCMind.py:
Ensure that Knowledge really does handle arbitrary triples.
* rulesets/basic/mind/goals/common/misc_goal.py: Add new version
of transaction goal for transactions for hirelings.
* rulesets/basic/mind/goals/humanoid/transaction.py: Complete
the implementation of the trigger goal for hirelings.
* rulesets/mason/define_world.py: Move the mercenaries closer to
origin for debugging.
* modules/Location.cpp, modules/Location.h: Improve algorithm
of distance function to handle corner cases, and add a second
interface so that both scalar distance and relative position
can be found.
* tests/distancetest.cpp: Update tests to test for cases where
distance to or from an entity directly below.
* modules/Location.cpp, modules/Location.h: Add new improved
function to measure the distance between two entities.
* tests/distancetest.cpp: New test for new distance measuring
function.
