ecsy-three | ECSY and three.js components , systems and helpers | Game Engine library

ecsy-three is a JavaScript library typically used in Gaming, Game Engine, Unity, Three.js applications. ecsy-three has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The core API for ecsy-three is just a few additional concepts on top of ECSY. First, you must create an instance of ECSYThreeWorld instead of World. ECSYThreeWorld registers a custom ECSYThreeEntity class with some helper methods for working with ThreeJS. You can add any Object3D to an ECSYThreeEntity using addObject3DComponent(object3D, parentEntity). addObject3DComponent() will add the Object3DComponent as well as a series of TagComponents. For example, when adding a Scene object3d to an entity, it will also add the SceneTagComponent. For the Mesh object3d, a MeshTagComponent will be added. These tag components can be used in System queries to get instances of certain object3ds. You can then use entity.getObject3D() to get the object3d for that entity. If you want to remove an Object3D from an entity, you can call entity.removeObject3DComponent() which will remove the object3D from the entity and detach it from its current parent as well as removing any object3d TagComponents. Finally, if you want to get the entity for a give object3d you can use object3D.entity. This property is added to the object3D when calling entity.addObject3DComponent and removed when calling entity.removeObject3DComponent(). That is essentially all there is to the ecsy-three core API at this time. With just these few additional components you can write most ThreeJS code against ECSY.
