I realized I forgot to add in the means to have it deactivate after a certain amount of time — we need IEnumerators! With our IEnumerator, we’re going to allow triple shot to be enabled for 5 seconds, then disable triple shot! We now need to make a call to it from our function, _tripleshotCheck()!

So our logic is going to be almost identical to our Enemy! We want the power-up to move down the board, but instead of respawning at the top in a random place we want to destroy it. …

It’s time to create our power-up! We’ve simulated triple shot through our Inspector through a toggle and now we need to make the actual pick-up! Drag a sprite of our choosing to the Hierarchy, renaming that sprite to “Triple_Shot_Powerup”, resizing the sprite, giving it a 2D collider and checking the “Is Trigger” box (because this will be an “OnTriggerEnter2D()” event!), and lastly adding a “Rigidbody 2D” with “Gravity Scale” set to zero!

Since our prefab is set-up, we can start working on the power-up. We’re essentially collecting a sprite that tells the Player, “Yo, you can use this” and enable the Player to “Triple_Shot”. Planning this out we need to check if Triple Shot is enabled, then fire the Triple Shot —…

Power up time! Let’s create our triple-shot laser by dragging our pre-existing Laser prefab into the scene, duplicate and adjust them to be in the position we would like them

We must rebuild this laser — it’s just easier that way. Let’s start by deleting the 3D “Laser” out of our “Prefabs ”folder then drag-and-drop our “Laser ”sprite from out of our “Sprites ”folder in the Project hierarchy onto our “Hierarchy”. Once it is in our Scene, resize it to…

Now that we have the basis set-up, let’s get our “Edit Collider” in our Box Collider 2D to match the size of our ship(s) more!

Let’s get to converting our villain to 2D by selecting him in our Project > Prefabs folder, then in the Inspector we want to select Open Prefab From here, you should see this in your Inspector! Let us remove the Mesh Filter, Mesh Renderer, Rigidbody and Box Collider. Why? We…

I forgot to mention in the last article that we need to assign proper layers to our sprites!
