I’m using a variable (Hit Actor) to record the actor that was hit by the trace. The Set node is being used to do that. So I am Setting the Hit Actor to be an object.
You don’t need to worry about it. It just comes in useful sometimes if you want to do anything more with the name of the object. You can do this instead. Don’t worry about the PickUpObject function, just create the cast node and then whatever you want it to do after that.
