How works the System

SFME systems are separated into different types:

• PreUpdate -> Called at each loop turn before logical systems (for example ProcessInput, ProcessNetwork)
• LogicUpdate -> Looped as long as it is allowed (for example GameLogic, Physics, Movement)
• PostUpdate -> Called at the end of the LogicUpdate (for example Rendering, Interpolation)

The class is templated on the entity manager and she is a receiver.
