Heyo, I’m back! Let’s do a life system thing. So, for literally anything to exist in your game — anything at all — you need to create it. Unless you’re using a template with premade assets and such, that means among other things, you need to create the concept of…

While we’re setting up a relatively simple system of interactions with the enemy, there’s still a lot that goes into it. First, let’s hit it with collisions. There are two general kinds of collisions we’re working with in Unity: hard-surface collisions — think throwing a ball at a wall; using…

Okay, so this is a two-fer because I made two graphics for what I thought would be two articles but they can easily be one, so here go. In the hierarchy create a sphere, name it Enemy, zero out the location, drag the object from the hierarchy to the prefab…

This is going to limit the rate of laserfire for the player. Declare two serialized private floats:

Scripting Laser / Projectile Behaviour As soon as our laser / projectile / object instantiates at the ship tip, it needs to travel up-screen. First things’ first: create a script in your scripts folder, name it laser, add it to the laser prefab, and open it in Visual Studio. Here’s…

We want to spawn, or instantiate, our laser bolt prefab from the tip of our ship when we press the “fire” button. The Unity manual tells us: To instantiate a Prefab at run time, your code needs a reference to that Prefab. You can make this reference by creating a…

If there’s one thing space shooter games are full of, it’s LASERs. So let’s go ahead and set up our primary projectile as a prefab so we can instantiate the crap out of it without expending too much on our systems. Create a capsule in your hierarchy. Right-click -> 3D…

Let’s do more of that optimisation. First, let’s create a new method, just for player movement.

Before we can set our boundaries, we have to know where we want them to be. We can do this by moving our player object to the upper, lower, leftmost, and rightmost sides of the screen and taking the coordinates from the inspector.
