Sandbox Graph

Sandbox Graph is similar to Blueprint but one of the main difference between Blueprint and Sandbox Graph is that, each node is a full UObject in Sandbox Graph where as in Blueprint they are functions nodes. That means, you can have your gameplay logic in a single node. Sandbox Graph spawns multiple nodes by default which are executed at various times. You can also create your own Graph Node via C++ or Blueprints. To create a new Sandbox Graph, right click inside Content Browser and from Sandbox category, select Sandbox Graph.

For custom behavior, you can create Custom Input node with an Event Name (similar to Custom Events in Blueprint) that can be called externally from Blueprint or C++. Sandbox Graph also provides multiple custom input nodes with various types such as bool, float, UObject, Gameplay Tags and more.
