Hi guys

Is there any reason why you get components by tag or using the method GetComponentByType<>? Doesn’t it add more overhead at the moment of loading the scene? This is what I have in my Cursor.cs and I reference the raycaster by dragging it in from the editor.

Is there any reason to NOT do that?

Thanks

public class Cursor : MonoBehaviour {

[SerializeField]CameraRaycaster raycaster;

// Use this for initialization
void Start () {
    Assert.IsNotNull(raycaster);
}

// Update is called once per frame
void Update () {
    Debug.Log(raycaster.layerHit);
}

}

Just a note, if you half-follow the video so that you have enemies in your scene, this won’t work yet if you used the same placeholders as in a previous video, since those placeholders don’t have a collider on them. I spent a good 40 seconds trying to figure out why the raycaster didn’t see the enemies :slight_smile: You have to add some kind of collider to test that feature.

DOH! well that explains it. I was trying to figure out as well why the enemies were not seen! :laughing:

Hi Ben,
First of all congratulations for the way you have structured the course and the clear and direct style. Being myself a teacher I really do appreciate the effort.

A small detail concerning your CameraRaycaster.cs script:
Why do not you build a layer mask holding the bits for the two layers and later check the object tag of the hit object?
