Gabriel Bourgeois 6b75589e2c Fix inconsistent children removal behavior (#6017) ... # Objective Fixes #6010 ## Solution As discussed in #6010, this makes it so the `Children` component is removed from the entity whenever all of its children are removed. The behavior is now consistent between all of the commands that may remove children from a parent, and this is tested via two new test functions (one for world functions and one for commands). Documentation was also added to `insert_children`, `push_children`, `add_child` and `remove_children` commands to make this behavior clearer for users. ## Changelog - Fixed `Children` component not getting removed from entity when all its children are moved to a new parent. ## Migration Guide - Queries with `Changed<Children>` will no longer match entities that had all of their children removed using `remove_children`. - `RemovedComponents<Children>` will now contain entities that had all of their children remove using `remove_children`.		2022-10-06 21:39:34 +00:00
