PathFinder status

[LogicParrot]

Still debugging. In the meanwhile, what do you think of this interface?

I recall you wanted a "dumb device" which receives coordinates are spits out a path. Ideally, this would have been a static class with a single function "getPath".
But I had to make instances because:

• MCserver is threaded, a static function seemed dangerous to me
  
• A mob might want to spread the load of calculating a path across several ticks, this is impossible with a single static function. A single static function would have to be blocking.
  

I'd love to hear if you have a better proposal.

    cPathFinder(
            double a_boundingBoxWidth,  // The character's boundingBox Width. (Currently preset to 1, parameter will be ignored)
            double a_boundingBoxHeight, // The character's boundingBox Height. (Currently preset to 2, parameter will be ignored)
            int a_maxUp,                // What is the highest wall this character can climb / jump? (Currently preset to 1, parameter will be ignored)
            int a_maxDown               // How far down is the character willing to fall? TODO more flexibility here.  (Currently preset to 1, parameter will be ignored)
            );

    ~cPathFinder();
    void findPath(int a_maxSearch, const Vector3d &a_startingPoint, const Vector3d &a_endingPoint);
    bool isCalculationFinished();
    cPath* getPath();

interface usage example:

//When a zombie is born...
m_pathFinder=pathFinder(1,2,1,1); //The parameters do nothing because they are not implemented yet
...
//When a zombie wants to attack someone.
pathFinder.findPath(100,myLocation,theirLocation);

//Every tick...
if (pathFinder.isCalculationFinished())
{
     myPath=pathFinder.getPath();
     //now walk that path.
}
