To find the background music track, we need to navigate to the appropriate folder in the Content Browser. This is where all the assets for our project are stored.

In the Content Browser, navigate to the folder where the background music is located. This could be a folder specifically dedicated to audio assets or a more general folder where all the game’s assets are stored.

Once you have located the folder, look for the audio file that represents the background music. The file may have a recognizable name or a specific format such as .mp3 or .wav.

If you’re having trouble finding the background music track, you can use the search functionality in the Content Browser. Simply enter keywords related to the music track in the search bar, and Unreal Engine 4 will filter the results to show you relevant files.

Once you have found the background music track, you’re ready to proceed to the next step: adding a new sound cue.

Step 5: Adding a New Sound Cue

In order to change the background music, we need to create a new sound cue. A sound cue is a blueprint that defines how a sound is played and manipulated in Unreal Engine 4. By creating a new sound cue, we can customize the playback settings for our new background music track.

To add a new sound cue, right-click in the Content Browser and select “Sound Cue” from the context menu. Alternatively, you can use the “Create” button in the toolbar and choose “Sound Cue” from the dropdown menu.

After adding the new sound cue, you can give it a descriptive name that reflects its purpose, like “BackgroundMusicCue.” This will help you easily identify and reference it in the Blueprint graph later on.

Once you have created the sound cue, you will be taken to the Sound Cue Editor. This is where you can define the audio properties and manipulate how the background music will be played in your game.

Within the Sound Cue Editor, you can add and connect various nodes to create a flow of audio. You can adjust volume levels, add effects, and even trigger different events based on certain conditions.

Now that you have created a new sound cue for the background music, we can move on to the next step: configuring the sound cue to match our desired settings.

Step 6: Configuring the Sound Cue

Now that you have added a new sound cue for the background music, it’s time to configure it to match your desired settings. The Sound Cue Editor provides an intuitive interface where you can adjust various parameters to achieve the desired sound and behavior.

First, select the sound cue that you created for the background music in the Content Browser. This will open the Sound Cue Editor, where you can see the nodes and connections representing the sound cue’s flow.

In the Sound Cue Editor, you can add audio components, such as sound waves, to your sound cue. To do this, right-click on the canvas and navigate to the “Sound” section. From there, you can choose different types of sound components to add to your sound cue, such as a sound wave or a sound class.

Once you have added the sound component, you can configure its properties, such as volume, pitch, and other audio effects. You can also connect the sound component to other nodes to create a flow of audio and define how it will be played in your game.

Within the Sound Cue Editor, you have access to a variety of nodes that can be used to modify and manipulate the audio. These nodes include volume modifiers, pitch shifters, and even more advanced effects like reverb and spatialization.

Take your time to experiment with different nodes and settings to achieve the desired background music effect. You can play around with the volume levels, fade-in and fade-out effects, and any other parameters that suit your game’s atmosphere.

Once you are satisfied with the configuration of the sound cue, you can move on to the next step: setting the background music track in the Blueprint graph.

Step 7: Setting the Background Music Track

With the sound cue configured in the Sound Cue Editor, it’s now time to set the background music track in the Blueprint graph. This step involves connecting the sound cue to the appropriate nodes and functions that control when and how the background music should play.

First, go back to the Level Blueprint by navigating to the Blueprint editor window and double-clicking on the Level Blueprint icon in the Content Browser.

Within the Level Blueprint, you can see the graph editor window where you will make the necessary connections and changes. This is where you can add nodes and define the logic for playing the background music.

Find the node that represents the event or trigger that will initiate the background music. This could be an “Event Begin Play” node, which is executed when the level starts, or any other custom event that you have created.

Next, right-click in the graph editor window, and in the context menu, search for and select the “Play Sound Cue” node. This node allows you to play the sound cue that you created for the background music.

Connect the output of the event or trigger node to the input of the “Play Sound Cue” node. This establishes the flow of execution and ensures that the background music is played when the specified event occurs.

Finally, select the “Play Sound Cue” node, and in the Details panel on the right side of the Blueprint editor, assign the sound cue you created for the background music track.

Now, when the event or trigger is triggered during gameplay, the background music track specified in the sound cue will start playing automatically.

You can further customize the behavior of the background music by adding additional nodes and logic to the Blueprint graph. For example, you could create a condition to fade the music in or out based on certain gameplay events.

With the background music track set in the Blueprint graph, you’re ready to move on to the next step: testing the background music in your game.
