Interactive nodes give outputs based on various kinds of live inputs. Most work with numerical values, although the RSS Feed Node and RSS Text Selector output a text string, and the Mouse Picker outputs translation data.

Interactive nodes can be applied to almost any attribute of a node, simply double-click a node in the nodegraph to see its drop down attribute list, and connect to the square next to the attribute. If an attribute isn’t in the drop down list, it cannot be modified with an interactive node.
