+# Nulls node
+
+> [!NOTE]
+> For versions 2019/2020 LTS, download the Visual Scripting package from the [Unity Asset Store](https://assetstore.unity.com/packages/tools/visual-bolt-163802).
+
+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.
