It seems a Tad unfair that we can shoot and the Enemy can’t (let’s change that).

Since I like Coroutine’s so much (and I’m sure you do to!!), I think this may be a good time to use one. I would like our enemy to fire 2 lasers every; lets say 2–4 seconds. First we will need to create the prefab of the two lasers; we can use the prefabs of the Player laser for this; I will call it DualEnemyLaser.

At the moment the Tag on the lasers is set to laser, we should add another Tag; let’s call it Enemy_Weapon (Weapon since I believe our enemies may have multiple by the end of the game). Then change the Tag of both lasers in our DualEnemyLaser prefab to this new Tag.

I have also changed names to enemyLaser in Inspector.

Now we need to write the code to use this prefab. To start we need to create a new script, let’s call it EnemyLaser. We can copy the code from the Player laser into this new script. We can adjust the speed of the laser to:

We will also need to adjust the direction the laser travels, and the value off the bottom of the screen where they will be destroyed:

Next, we need to figure out where the code should go to instantiate the DualEnemyLaser. This of coarse, should be located in the Enemy script. First we need to add a variable:

Save the script, jump back into Unity, drag and drop the DualEnemyLaser prefab into the newly created Enemy Laser field on the Enemy prefab. Next, we need to create a Coroutine to instantiate the DualEnemyLaser prefab:

Then we just need to add the below to the Start method of the Enemy script:

And, in order for these lasers to damage our player, we need to add an OnTriggerEnter method to the Update() method of our Player script:

Saving all our scripts, jumping back into Unity and running the game will give:
