Unity ECS 纯代码生成Entity

核心方法：EntityManager.CreateEntity（）+ 多个重载 1. params : ComponentType[] types

	 Entity entity = World.DefaultGameObjectInjectionWorld.EntityManager.CreateEntity(
            typeof(Translation),
            typeof(LocalToWorld),
            typeof(RenderMesh),
            typeof(Scale),
            typeof(Unit)
        );

2. CreateArchetype( ComponemtType tpye ,xxxx)

原型可挂载多个ComponentData，可配合NativeArray生成多个Entity

{
	var entityManager=World.DefaultGameObjectInjectionWorld.EntityManager;
	NativeArray<Entity> entityArray = new NativeArray<Entity>(10, Allocator.Temp);
    EntityArchetype entityArchetype = entityManager.CreateArchetype(typeof(RenderMesh),				   
    	typeof(LocalToWorld),typeof(Translation), typeof(RenderBounds), typeof(Rotation));
    entityManager.CreateEntity(entityArchetype,entityArray);
}
