if( Entity( _entityMap[ a_id ] ) == null )
{
throw new Error( ” There was no entity with a matching id.” );
return;
}

//_entityMap[ a_id ].dispose();
delete _entityMap[ a_id ];
}

This block of code from Entity.as has the line _entityMap[ a_id ].dispose(); commented out. I am not sure if this was because it was planned for later or what nor did I research what this map did but needless to say uncommenting it fixed the removal issue.

So after change looks like this and works as expected again along with the super slowness/freezing goes away. I assume this non removal is hogging up all the memory. Anyway, hope this was helpful.
public function removeChild( a_id:String ):void
{

if( Entity( _entityMap[ a_id ] ) == null )
{
throw new Error( ” There was no entity with a matching id.” );
return;
}

_entityMap[ a_id ].dispose();
delete _entityMap[ a_id ];
}

Basically, the issue I found was the following, in the code if you get a rounding error due to something directly facing something when you ask for the angle you get a NAN when pointing at something or point directly away.

public function angleTo( vector:Vector2D ):Number
{
return Math.acos( dotOf( vector ) / ( length * vector.length ) );
}

Need to check the return and see if it is out of range of acos and if is return 0 or pi depending on which direction.

I would post my corrected code but I am at work and don’t have it. Also, it is under a different method because it does screw up some of the steering behavior once corrected.

Really happy to see you reposting and really like the infastructure you have created.

I was so excited to see a new update in my RSS feed, I hope to see a lot more!
