Do you want an enemy to spawn after the Player finishes reading the Note he picked up? If so, after the Player presses any button and you remove the Note from the Viewport, you can use the “spawn actor” node. The actor class should be the Enemy blueprint class. For its transform, take your player’s forward vector, multiply it by some negative number(say 400), add that to the player’s world location, and give that location to the Spawned enemy.
