There is no 'Animation' attached to the "person" game object, but a script is trying to access it

Question

Picture: Object Hierarchy

I want to Play Animation when Virtual Button Pressed using Unity & Vuforia. But i don't know why i got an error "there is no 'Animation' attached to the game object"

I'm using Unity 4.7.0 and Vuforia 5-0-10

This is the code that attached to the ImageTarget

using UnityEngine;
using System.Collections;

public class VBEventHandler : MonoBehaviour, Vuforia.IVirtualButtonEventHandler {

public GameObject person;

void Start(){
    Vuforia.VirtualButtonBehaviour[] vbs = GetComponentsInChildren<Vuforia.VirtualButtonBehaviour> ();
    for(int i=0; i<vbs.Length; i++){
        vbs[i].RegisterEventHandler(this);
    }

    person = transform.FindChild("person").gameObject;
}

public void OnButtonPressed(Vuforia.VirtualButtonAbstractBehaviour vb){
    switch (vb.VirtualButtonName) {
        case "VBAnim":
            person.animation.Play();
            break;
    }
}

public void OnButtonReleased(Vuforia.VirtualButtonAbstractBehaviour vb){
    switch (vb.VirtualButtonName){
        case "VBAnim":
            person.animation.Stop();
            break;
        }
    }
}

am I missing something?

Answer 1

Note that the error says

there is no 'Animation' attached to the game object

I'm thinking, it is very likely that

there is no 'Animation' attached to the game object

What you should do is check if

there is no 'Animation' attached to the game object

You may find that

there is no 'Animation' attached to the game object

If it turns out

there is no 'Animation' attached to the game object

then you've discovered the problem you're having,

there is no 'Animation' attached to the game object

Heh! It's that easy.

Setting aside the humor, do note that these days

You attach an Animator. You don't, really, use animations directly.

Review basic tutorials on animating humanoids in Unity. ( UMotion is highly recommended when working with animation in Unity.)
