This is illegal and produces undefined behavior (or oddness like only iterating over a subset of all items in the collection) for most data structures in almost all languages. This is a basic programming question, nothing super specific to games, C#, or Unity. | |

The expected output: parent all children to obj. The output without the while loop: only some children are parented to obj, some remain parented to transform
