Class SystemInvocationStrategy

java.lang.Object

com.artemis.SystemInvocationStrategy

Direct Known Subclasses:

InvocationStrategy

public abstract class SystemInvocationStrategy
extends Object

Delegate for system invocation. Maybe you want to more granular control over system invocations, feed certain systems different deltas, or completely rewrite processing in favor of events. Extending this class allows you to write your own logic for processing system invocation. Register it with WorldConfigurationBuilder.register(SystemInvocationStrategy) Be sure to call updateEntityStates() after the world dies.
