Physics
The basic loop of the physics engine
1. Apply forces, position changes and rotations
to the bodies and geometries.
2. Calculate the collisions between the
corresponding bodies for each iteration.
3. Let the simulation calculate one step.
4. Clear all contact joint information.
5. Apply the new positions and rotations to the
visual objects.
6. Loop to point 1.

estimated total cost of path through
the current node n to the goal.G (n) the total
cost of path from the start node to
the current node n.H (n) true cost from the
current node n to the goal.

handles all packages separately according to the
time stamp of the package
Only after the current updating of the world is
finished, the other packages in the waiting list
may proceed to be processed
