I have been working on programming a graph in Unity that rotates based on head movement. I have been having multiple issues with the rotation aspect of it.
A sample of the Autowalk class, which I am using to find the angle that the graph needs to rotate based on where the user is facing:
public class AutoWalk : MonoBehaviour {
//VR head
private Transform vrHead;
//angular displacement from normal
public float xAng, yAng, zAng;
//previous values
public float xOrig, yOrig, zOrig;
// Use this for initialization
void Start () {
//Find the VR head
vrHead = Camera.main.transform;
//finding the initial direction
Vector3 orig = vrHead.TransformDirection(Vector3.forward);
xOrig = orig.x;
yOrig = orig.y;
zOrig = orig.z;
}
// Update is called once per frame
void Update () {
//find the forward direction
Vector3 forward = vrHead.TransformDirection(Vector3.forward);
float xForward = forward.x;
float yForward = forward.y;
float zForward = forward.z;
//find the angle between the initial and current direction
xAng = Vector3.Angle(new Vector3(xOrig, 0, 0), new Vector3(xForward, 0, 0));
yAng = Vector3.Angle(new Vector3(0, yOrig, 0), new Vector3(0, yForward, 0));
zAng = Vector3.Angle(new Vector3(0, 0, zOrig), new Vector3(0, 0, zForward));
//set new original angle
xOrig = xAng;
yOrig = yAng;
zOrig = zAng;
}
From there I go to the ReadingPoints class, which contains all of the points on the graphs (spheres) and axes (stretched out cubes):
public class ReadingPoints : MonoBehaviour {
// Update is called once per frame
void Update () {
float xAngl = GameObject.Find("GvrMain").GetComponent<AutoWalk>().xAng;
float yAngl = GameObject.Find("GvrMain").GetComponent<AutoWalk>().yAng;
float zAngl = GameObject.Find("GvrMain").GetComponent<AutoWalk>().zAng;
if ((xAngl != prevXAngl) || (yAngl!=prevYAngl) || (zAngl!=prevZAngl))
{
//rotate depending on the angle from normal
foreach (GameObject o in allObjects)
{
o.transform.Rotate(new Vector3(xAngl, yAngl, zAngl), Space.World);
prevXAngl = xAngl;
prevYAngl = yAngl;
prevZAngl = zAngl;
}
}
allObjects, as the name implies, contains the points and the axes.
Anyway, the first issue that is upon running the program is that the graph appears to be torn apart. How the graph is supposed to look (this is what it looks like when o.transform.Rotate(...) is commented out) Here is how it actually looks :( Also, the graph does not rotate when I move, and I have no idea why (I thought I might be using the Rotate function improperly but perhaps I also didn't find the correct angles?). Any ideas of what went wrong are much appreciated, thank you!
