Hello,
I'm developping an app in which we enable a 3Dmodel depending on the string value of the Vumark. My Logic is to create two seperate scripts :
- The first one "VumarkCheck" is to detect the new vumark and extract its string value.
public class VumarkCheck : MonoBehaviour {
private VuMarkManager mVuMarkManager;
public Model3DScript model3DScript;public GameObject[] Model3D = new GameObject[2]; //3d model of AR
void Start()
{
model3DScript = new Model3DScript();
// register callbacks to VuMark Manager
mVuMarkManager = TrackerManager.Instance.GetStateManager().GetVuMarkManager();
mVuMarkManager.RegisterVuMarkDetectedCallback(OnVuMarkDetected);
mVuMarkManager.RegisterVuMarkLostCallback(OnVuMarkLost);
}void OnDestroy()
{
// unregister callbacks from VuMark Manager
mVuMarkManager.UnregisterVuMarkDetectedCallback(OnVuMarkDetected);
mVuMarkManager.UnregisterVuMarkLostCallback(OnVuMarkLost);
}public void OnVuMarkDetected(VuMarkTarget target)
{
string vumarkString = GetVuMarkString(target);
Debug.Log("New VuMark: " + GetVuMarkString(target));
model3DScript.Show3Dmodel(vumarkString);}
public void OnVuMarkLost(VuMarkTarget target)
{
Debug.Log("Lost VuMark: " + GetVuMarkString(target));
}private string GetVuMarkString(VuMarkTarget vumark)
{
switch (vumark.InstanceId.DataType)
{
case InstanceIdType.STRING:
return vumark.InstanceId.StringValue;
}
return "";
}
}
- The second one "Model3DScript" is to enable and disable Gameobject depending on the string value of the detected vumark.
public class Model3DScript : MonoBehaviour {
//3d models
public GameObject[] Model3D = new GameObject[2]; //3d model of AR
public void Show3Dmodel (string VumarkString)
{
if (VumarkString = "XXX")
{
Model3D[0].SetActive(true);
}
else if (VumarkString = "YYY")
{
Model3D[0].SetActive(false);
Model3D[1].SetActive(true);
}
}
}
I attached two gameobjects to my Array Model3D from the unity Inspector.
My problem is that each time, the Show3Dmodel method is called, I get an error message : "IndexArray is out of range".
I checked the elements of my Model3D array in Debug mode, I have found that my array contain null objects. But in the unity inspector, I see my Model3D in my array.
How can I solve this problem? I don't want to instantiate my Model3D array in the same script of VumarkCheck.
