Creators – Week 2

Hi folks, this week we started our first project. We have a truck that can drive down a road, avoiding obstacles, or maybe not!

We created a new project in Unity, using the default 3D Core template, and called it Prototype 1.

We then downloaded and imported the assetpack from here: [Creators Teams Channel]

The asset pack already included an existing scene, which had a simple environment already. We them dragged in a vehicle and obstacle from the imported assets. Imported assets aren’t just models; they can contain Unity obstacles, such as colliders, already.

To make the truck move, we made a new C# script called PlayerController. The new C# files Unity creates always look the same (apart from the name of the Class, which matches the new file name):

We added the following code to the Update() method to change the transform of the vehicle:

    // Update is called once per frame
    void Update()
        //  Move our vehicle forward
        transform.Translate(0, 0, 1);

The Unity scripting documentation can be found:

and the specific page for the Transform component is:

This method on the Transform component that we’re calling, Translate() has several forms. The one we’re using here expects us to provide X, Y, Z values. What we’re saying we want to happen is “Change the transform by moving it 1m in Z every frame.

When we run, the car moves very fast off the end of the road. That’s because we’re running at many frames a second. It’s too fast. Next week, we’ll look at making this frame rate independent and controlling the speed.

Finally, I’ve created a GitHub repo for our projects this year. Up-to-date versions of our projects will always be available here after our sessions:
