Intermediate Level 14: Making sounds from moving objects
Here's how to make a sound come out of a moving object.
As an example, let's try making the propeller noise from a helicopter.
Introducing helicopter uasset
We have prepared a moving helicopter uAsset so that you can actually hear the sound coming from a moving object.
Please download from the link below.
When you unzip the downloaded tutorial_sample_ue4_lesson14.zip, a file called Heli_Move_Blueprint.uasset will be created.
Place this file in the Content directory.
Place the Heli_Move_Blueprint on the level (it doesn't matter where you place it).
Now when you run the game, you'll see a helicopter flying around in the sky.
How to make a sound from a moving object?
This is the perfect implementation for when you want to play a sound from a moving object.
This is an implementation method in which a sound source is attached to an object (actor).
Specifically, this is achieved by adding a component called "Atom Component" to the actor.
With the Heli_Move_Blueprint selected, click "Open Blueprint Editor" from the "Edit Blueprint" menu.
This will add the Atom component.
Select the Atom component you just added and look at the details window.
This time, set the Sound to 3D_Sound_Heli_Loop_3D_Cue.
Listen to the sound
Start the game and listen to the sound.
Make sure you hear the propeller noises from the helicopter as it moves around.
As the helicopter moves left you will hear a sound from the left, the sound gets louder as the helicopter gets closer.
