How to make an item disapear

Hello i have a hammer that i want when i look at it say “Press E to grab the Artifact”.
Then i press E to make it disappear.
Also after that happens i want a rock mesh to fall.
is this possible?

This seems like triple question :),
you could make things disappear by applying an invisible material.
But it seems what you want is to destroy it, you can “Destroy” actors.
To make a rock mesh fall you’d have to make a rock mesh and spawn it in wanted position,
you’d also need to turn on physics on the rock so it would be affected by gravity and would automatically fall down.

Hey Thanks for the help.How can i make a text appear and also how can the rock fall only when i make the hammer disappear?
