[Tạo 2D Platformer Game với Godot] Part 28: Adding interface sounds

In this section, I will show you how to add sounds when clicking buttons on the interface, etc.

Sound

Get the sound

To get the sound, I won’t need to give you the download link here, you just need to go to the Asset lib to find Kenney and it will come out.

You can choose one of the two.

Then click download to download it.

Once the download is complete, click Install to install it.

It will display an interface showing the address of that addon and then click Install

Then a new folder is created named addons and it contains the sound that I just installed in it

Regarding the audio files, it is also labeled with the name in front so you can know which one to use and which one to use.

Add to scene

After successful installation, I proceed to add it to the game.

Get yourself an AudioStreamPlayer2D node node

Here I am adding to the Menu scene.

Here I am doing Audio when I click the Start button so I will find the sound named click and drag it into the Stream of Audio Stream Player 2D.

After dragging is done, you can call it in code with the play() function.

extends Control
func _on_NutBatDau_pressed():
    $AudioStreamPlayer2D.play()
    yield(get_tree().create_timer(0,1),"timeout")
    get_tree().change_scene("res://Scences/Map/LevelMap.tscn")
    pass # Replace with function body.
func _on_NutThoatGame_pressed():
    get_tree().quit()
    pass # Replace with function body.

The line of code above, I added the line $AudioStreamPlayer2D.play() I will play the sound when I press the start button

yield(get_tree().create_timer(0,1),"timeout"): is that I create a timer with gin 0.1s, after 0.1s is over, it will run the change_scene() command. Here, I use this command because when I press just add the play() line and then change_scene it will not play the sound (depending on the device) so I will add the yield command so that after it plays the sound, then change scene.

You may not need to add yield() if the one you want to play the audio doesn’t need to change the scene.

I will make one more in the PauseMenu scene.

You add sound.

Then in the function that shows the menu sound I have:

func _on_HienPauseMenu_pressed():
    
    get_node("AudioStreamPlayer2D").play()
    $PauseMenu.show()
    get_tree().paused = true
    pass # Replace with function body.

Then after you press and test it, you will see it has a click sound when clicked.

Summary

So in this part, I showed you how to add sound to the game.
