The level manager service provides a simple mechanism for loading a
level into a world. It has one method,
Load, which accepts a reference
to the current world and the name of the level asset. In the context
of a world, it can be used like so:
The default level manager implementation uses the
to load entities, before it adds them to the world.
Please note that calling
Load does not remove previous entities from the
world, so if you are loading a different level, remember to remove all
entities from the world that you do not want to have persist between levels.
