Trigger Event VS
In Visual Scripting you can use
Spatial Trigger On Enter and Spatial Trigger On Exit events to execute any sort of function when an avatar enters/exits a trigger respectively.
When using VS you can leave the enter/exit events blank in the inspector.
In the example below I am setting a bool to true when the user enters the trigger, and false when they leave.
