prefab.parent (procNode)

Set the parent of an entity in a prefab, the reusable entity template a spawn copies, the child and the parent identified by name. Use it to regroup entities after they were added. The parts a graph builds and parents itself are elements: elements.entity makes one and elements.link parents it under another.

Built from prefab.edit (what = "parent").

Inputs

• prefab (Prefab). The prefab the move happens inside. It comes out as a new value; both names are resolved against this one prefab.
• child (String, default ""). The name of the entity to move. Every record carrying that name is moved, the root excepted, so a name shared by several children regroups all of them at once; a name the prefab does not carry leaves the hierarchy as it was.
• parent (String, optional). The name of the entity to hang the child under. Left out, or naming an entity the prefab does not carry, hangs it on the root.

Outputs

• prefab (Prefab). A new prefab value, { records = { ... } }; the prefab wired in keeps the records it had.
