Can't attach animation to script

Question

I'm working on a little game (which is also my first one) and I want to insert a splash screen at the beginning (after the Unity one). I've finally achieved to add a fade-in and a fade-out transistion when the splash screen starts and ends, but the fade out is activated by a button and I wont to play it simply after a certain time. I've made a script for that:

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class FadeInOut_2 : MonoBehaviour
{
    public Animation anim;

    IEnumerator Start()
    {
        yield return new WaitForSeconds(2f);

        anim.GetComponent<Animation>().Play();

        Application.LoadLevel(Application.loadedLevel + 1);
    }

}

The problem is: when I try to attach the animation the Inspector refuses to do it.

Any ideas? Thanks

Answer 1

You aren't waiting on the animation so once you play it Application.LoadLevel just does its thing and you wont notice the animation.

First, you'll need a way to wait on the animation which could be a simple coroutine:

private IEnumerator WaitForAnimation ( Animation animation )
{
do
    {
        yield return null;
    } while ( animation.isPlaying );
}

And then use it to yield before calling Application.LoadLevel:

    ...
    anim.Play();
    yield WaitForAnimation(anim);

    Application.LoadLevel(Application.loadedLevel + 1);
}

Also, you don't need to call GetComponent<Animation> on an Animation.

I noticed that you created a coroutine but never called it, by using StartCoroutine().
