Make a rock fall

I’m Having trouble with a simple action for a blueprint. I want it to on event begin play, have the rock fall down. I just don’t know what function or action I need to make the actor i have reference to move.
Thanks

Well what is the current state of the rock? If it is an actor that is already spawned, then go into the blueprint components, and set ‘Simulate Physics’ to be checked for the rock component. If it is not spawned, then on Event Begin Play, call Spawn Actor from Class, and choose the rock blueprint to be the class, and then make sure ‘Simulate Physics’ is true.
