Developing game flow using script graphs

Note
For versions 2019/2020 LTS, download the visual scripting solution from the Unity Asset Store.

Script Graphs are the main tool for creating interactions in projects. Using unit-based actions and values, these graphs execute logic in a specified order, either at every frame or when an event occurs.

Units as building blocks

Units are the most basic element of computation in visual scripting. They are represented as nodes with input and output ports in script graphs.

Connecting units

Connections are formed by linking output and input ports on compatible units.

Using relations to debug

Although relations are predefined for each type of unit and cannot be edited, relations are useful to understanding the dependencies between each port of a unit. As well, visual scripting uses relation information in the background for predictive debugging.

Predictive debugging

Visual scripting predicts and indicates units that cause errors before entering play mode.

Reuse graphs with super units

Super Units are script graphs that are nested in a parent script graph as a single unit. They are a powerful feature for you to re-use and organize your script graphs.
