Objective: We need to add sound effects to play when the laser is fired.
To start, we should add an audio source component to the player. Then in the player script we need to add a variable that holds the laser sound clip and a variable to the audio source component that we just made.

with the audio source variable made we need to get the component in void start and then null check it.

Objective: We need to create the enemy lasers.
To start, we need to need to drag our enemy prefab to the hierarchy and put a laser prefab in the hierarchy as well then duplicate it. Next we need to position the lasers to where they will be shot from and create a new empty game object and that’ll hold our two lasers and that will be our enemy shots. Make sure the lasers are positioned a bit outside the collider of the enemy or it’ll just destroy itself.
Objective: We need to add some background music for our game.
To start, we should set up an empty game object that represents our audio manager and also create a empty child object that represents our background audio.

Next on the background object we need to add a component called audio source that’ll handle the functionality of playing our background audio. When the component is added drag your audio file to where it says audio clip and then make sure play on awake and loop are check marked so the music starts when the game starts and it doesn’t stop.
