| Null nodes deal with the null value, which is scripting lingo for "nothing". | |
| ## The null node | |
| The null node 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 node provides a fallback value in case the original input is null. | |
| For example, the null coalesce node defines a default fallback audio clip in case the one on the audio source is missing. | |
