Zay-ES (pronounced like Doctor Zaius from Planet of the Apes) is a high-performance Java-based Entity-Component-System that manages to side-step most/all of the typical disadvantages of an ES architecture without sacrificing ES "purity".
Zay-ES-Net is the add-on extension that provies client/server networking.

Just wanted to create an issue here, for future resolve. It's regarding the bugs when moving entities directly from the current zone+radius to outside the bounds (then the view is not updated):
https://hub.jmonkeyengine.org/t/simethereal-sim-eth-es-warping-entities/37283/8
In example project MonkeyTrap
DropShadowFilter : https://github.com/jMonkeyEngine-Contributions/zay-es/blob/master/examples/MonkeyTrap/src/trap/filter/DropShadowFilter.java
error in this line and this line
GeometryList casters = rq.getShadowQueueContent(ShadowMode.Cast);
When I remove an entity from EntityData using removeEntity() method, it publishes an EntityChange event for ALL the component types even if that entity does not have the component at all. It is because the removeComponent() method does not check the result from handler to see if the remove operation is valid or not before it publishes the event in this line:

It would be nice to let the user be able to provide a custom database password with SqlEntityData.

Hi
Array type is supported in standard sql as well in hsqldb. See http://hsqldb.org/web/howToArrays.html.
In the above link it describes an example of using array is to store Polygons which is exactly my usecase.
I am using a dynamic polygonal path finding library, there we need to create obstacles out of polygons or polylines and add the to navigation space.
I need to save polygon vertices for obstacle in a float [] field in Obstacle component.
Please take a look at the readme for this project https://github.com/implicit-invocation/jwalkable.

I had NPE while using zay-es-net. It appears that the client is receiving an EntityDataMessage, but there is no corresponding activeSet for the received ID anymore. This could be the case if the client calls EntitySet.release(), but then receives some new data for this set.
I use a custom network connection via Steam P2P. Maybe this forces the NPE if a message takes more time than usual to get to the client.

Hi
Using a “protected” no-arg constructor for my PersistentComponents I get an IllegalAccessException when requesting the component from EntityData.
It would be nice to add support for “protected” no-arg constructors in the Zay-ES persistence module.

Hi
I want to make a patch for this issue https://hub.jmonkeyengine.org/t/understanding-stringindex-interface-in-package-com-simsilica-es/37143/5?u=ali_rs
If getStringId("some string", false) can not find id for "some string" it will return null Integer result.
Now, the result has to be unboxed again to int, because the return type of the method is int. If you unbox an Integer that is null, you get a NullPointerException.
There is two way to fix it:
1- Change return type to Integer instead of int
2- or return -1 if result is null
Which one do you prefer ?
It would be nice to add EntityData.removeComponents(EntityId entityId, Class<T>... types) for ease of removing multiple components at once.
Currently, I am doing something like
Stream.of(ComponentA.class, ComponentB.class, ComponentC.class)
.forEach(component -> ed.removeComponent(eId, component));
