Entity System: A part doesn’t include any game sense and only holds a piece of data. Your typical element will include getters, setters, and data items. A thing is a set of elements. A system is usually an execution that iteratively functions on several things that share common elements.
Artemis is a framework to handle Entities in a world of games, and is a high performance framework of Entity system for games, which is written in Java. Here are the details given in Gamadu about this Entity system.
Artemis library is just 26 KB in size, it’s no dependencies and may be used with library or any game framework, 2D or 3D. The framework is composed with the help of Tiago Costa and by Arni Arent.
In addition, it uses design thoughts from Rapid Thing Component System, but expanded to manage “facets” of things, which is a set of elements. Artemis goes considerably farther.

The framework provides multiple kind of systems, and there exists a demo game supplied. Use is not complex and functionality is outstanding.
Say you need/need to alter your game from a 3D free-roaming game into a 3D sidescroller. Since no parts or systems even know it exists, no parts or other systems must shift as a result of the change of MovementSystem.
The parts are straightforward totes of information, as a programmer, and because the things are straightforward totes of parts with crafting the systems you actually just need to concern yourself. The systems can readily take care of composing the important elements within each thing, and beyond that they will have no limitations in how matters are processed by them. What this means is it is possible to concentrate on building systems that are powerful to solve problems in ways that are creative.
Despite appearances, this can be only a static outline of some of the things it does by itself and the Artemis framework fits together. I’m not going into all different things Artemis enables you to do; I’ll attempt to cover some of those in places that are different in the close future.
I can one thing that, when Artemis is in use, the process of improvement will be much better. It is possible to handle the execution of one facet of your game.
