I want sound to play a big role in my environment, so I set out to make it so when you gaze at the spheres to teleport to that location, it also plays a sound cue. I downloaded several royalty-free sound effects and music from PurplePlanet.com and Dig.CCMixter.com including some deep bell and gong sounds.
I then imported them as .wav files into Unreal. You have to convert them to a Cue, by simplying right-clicking and choose “Create cue.”
Then you select the trigger capsule you wish to play the sound, and right-click, choose “Add Event / OnActorBeginOverlap”.
At this point, Unreal switches you to the Level Blueprint, where you can begin to work with the Event. Pull out a wire to Play Sound at Location, then near the Sound input, select the sound cue you want to play from the pull-down menu. It’s that simple!
