Trigger an animation in Unity Augmented Reality with a collision (SDK: Vuforia) and problem with a tutorial

February 1, 2021 - 11:53am #1

Hello Everyone,

I am kind of new to Unity and I am trying to get two bodies to interact with each other via an animation when they're in close proximity.

When these 2 bodies are separated they're supposed to be idle.

One of the bodies has a rigid body and box collider. The other one only a box collider with a trigger.

I used 3 states in my animator, to trigger the animation I used a boolean condition.

This is my script:


using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class Kollision : MonoBehaviour


    [SerializeField] private Animator myAnimationController;

    // Start is called before the first frame update

    private void OnTriggerEnter(Collider other)


        if (other.CompareTag("Player"))


            myAnimationController.SetBool("Zusammen", true);




    // Update is called once per frame

    void Update()






I can't get the animation to start. Can you please help me?

The version I'm using is Unity 2020.1.11f1


My second question is regarding the tutorial from the Vuforia library: How To Dynamically Add Content to Targets in Unity

I think the code is deprecated, I replaced ITrackableEventHandler with DefaultTrackableEventHandler. I had a second mistake that I coulnd't find an answer for

What should I replace mTrackableBehaviour.RegisterTrackableEventHandler(this); with?
