About
The system manager class controls references to the systems.
Implementation
Before attempting to use a system, it must be registered.
Registration requires a call to registerSystem(String systemName, ECSSystem system), with params of the String name and a object reference of the ECSSystem. Using the object reference, a system can be invoked at any time.
Constructors
Default constructor
public SystemManager(){}
Methods
entityDestroyed
public void entityDestroyed(int entity);
Removes the specified entity from every system, if it was associated
entitySignatureChanged
public void entitySignatureChanged(int entity, BitSet entitySignature);
Checks the entity's new signature against the current registrations. Registers the entity if it wasn't previously registered, or removes it if it is no longer registered.
registerSystem
public boolean registerSystem(String systemName, ECSSystem system);
Registers the specified system name and system reference to this manager.
adds a systemName:system pair to systems
and a systemName:new BitSet() pair to signatures
setSignature
public void setSignature(String system, BitSet registrations);
Sets the required signature of the system
Fields
signatures
Map<String, BitSet> signatures = new HashMap<>();
systems
Map<String, ECSSystem> systems = new HashMap<>();
