Implementing the Pickup and Drop functions

Now that we've added this interface to the BP_PickupCube class, we can implement the functions we declared in that interface in our event graph. Let's get started:

1. In your Event Graph, right-click and select Event Pickup to create a Pick up event. This event exists on this Blueprint class now because we've attached an interface that declares it. You'll see that the event indicates that it's an interface event from BPI_PickupActor.
2. Create a Drop event in the same way.

Now that we've created handlers for the two events coming from our interface, let's make them work.

When this object is picked up, we want to turn off its physics simulation so that it doesn't fall out of our hand, and we want to attach it to a scene component on the hand that's picking it up.

3. Drag a reference to the Static Mesh Component onto the Event Graph.
4. Call Set Simulate Physics on it, setting Simulate to False.
5. Right-click in the graph and select Get Root Component.
6. Drag a connector...
