Null units deal with the null value, which is scripting lingo for "nothing".
###The null unit
The null unit always returns null as a value. Leaving a Unity object reference field empty ("None") automatically means null.
###Null Check
The null check is a shortcut for a branch on an equality comparison with null. It can be useful to direct the flow in different directions depending on whether a value is null.
For example, it can be used to handle a situation differently whether a transform has a parent in the hierarchy or not.
###Null Coalesce
The null coalesce unit provides a fallback value in case the original input is null.
For example, the null coalesce unit defines a default fallback audio clip in case the one on the audio source is missing.
