类名称：Entity
方法名：addChild

Entity.addChild介绍

[英]Add a child Entity, and set this entity as its parent, returning the added child.

As with #addChild(EntitySpec) the child is not brought under management as part of this call. It should not be managed prior to this call either.
[中]添加子实体，并将此实体设置为其父实体，返回添加的子实体。
与#addChild（EntitySpec）一样，此调用不会将子项置于管理之下。也不应在此调用之前对其进行管理。
