Types of Nodes

In Visual Scripting, you define your logic through a series of nodes. There are different types of nodes that help you work with logic, Lens Studio, and more.

Event Node

The root of any action in the graph. Information about the event, like the position of the touch in a TouchStartEvent, can be accessed by using the self port in the upper right hand corner.

Input Node

How to get outside input from the scene into the graph via the Script Component. If used inside a sub-graph it can either take input from the next graph level up, or on the Script Component as usual. Analogous to //@input when writing script code.

Asset Reference

Drag and drop any asset into the graph to create this node which then provides a reference to that asset without needing to otherwise use it in the scene. A Material referenced this way will populate the getProperty and setProperty nodes with the properties exposed by that Material for easy connections to Material Editor materials.

Custom Node

Drag and drop any script file into the graph to create a node which will execute the contents of the script. Use the normal // @input syntax to create input ports to the node, and a similar // @output syntax to create output ports. Useful for writing more computational small functions if you are comfortable, or working with scripts shared by other creators.

Take a look at the custom node guide for more information about input and outputs.

Sequence Node

A useful organizational tool that lets you split execution into multiple lines that will run in sequence. Functionally no different than connecting the end of one to the beginning of the next, but helps keep discrete parts of your graph separate.

Variable Nodes

These are two nodes, getVariable and setVariable which allow you to store values between events. The variables your graph uses are configured in the sidebar of the Visual Script Editor.

Control Flow Nodes

All the usual control flow options are available, if is the most important but while, for, break, and continue are all there as well.

Sub-Graphs

Sub-graphs are another organizational tool which allow you to separate a section of the graph into another layer, exposing inputs and outputs from that section. They are useful for encapsulating chunks of logic like the Lerp function below, and can be exported and reused in different graphs.
