Direct Event Binding in UEFN

If you’ve ever created an island in Fortnite Creative, you’ll be familiar with the channel system that uses transmitters and receivers to send signals between devices. Unreal Editor for Fortnite (UEFN) uses a direct event binding that allows devices to talk to one another directly by using functions. In other words, it binds an event (a trigger) from one device to a function in another device. Think of events as transmitters and functions as receivers, where one device’s event tells another device to perform a function. For example, the event of a player spawning on a spawn pad causes the Prop Mover device to begin moving a prop back and forth.
