Unity Engine

Hi, can anyone help me. I want to be able to call the function OnTrackingFound(): from the script so i can manipulate it in another script. Can anyone explain how to do that. I am using the ar script from vufroria.

Use the code tool in the post to format the code better.

In the other script, add:

DefaultTrackableEventHandler defaultTrackableHandler;

And then you can call OnTrackingFound () like this:

 defaultTrackableHandler.OnTrackingFound ();

Thanks For the Helps But when I put in this code;

    DefaultTrackableEventHandler defaultTrackableHandler;

its says ;
error CS1031: Type expected

Heres the other script I’m starting

using UnityEngine;
using System.Collections;

public class Spawn : MonoBehaviour

    DefaultTrackableEventHandler defaultTrackableHandler;


{
   
    void Start ()
    {
        defaultTrackableHandler.OnTrackingFound ();
    }

}

I think it might be the namespace. Maybe add

using Vuforia;
