I am getting this error when I click play: NullReferenceException

This is the code:

animation[takeOutAnim].speed = (animation[takeOutAnim].clip.length/.6);

animation.Play(takeOutAnim);

The exception means you are trying to do something with a null object. Your two lines of code would produce that error if `animation` is null, if `animation[takeOutAnim]` is null, or if `animation[takeOutAnim].clip` is null.

You can add some error-checking code to find out which is the problem, like so ...

if (animation == null)
{
    Debug.Log("animation is null!", gameObject);
}
if (animation[takeOutAnim] == null)
{
    Debug.Log("animation does not contain takeOutAnim!", gameObject);
}
if (animation[takeOutAnim].clip == null)
{
    Debug.Log("animation clip is null!", gameObject);
}

animation[takeOutAnim].speed = (animation[takeOutAnim].clip.length/.6);

animation.Play(takeOutAnim);

There's your problem then. What is the value of takeOutAnim? Either the string is wrong, or the animation doesn't contain the clip you think it does.

Where do you declare takeOutAnim? (Maybe you mean "takeOutAnim", i.e. the string itself?)

I tried to add it but then another error appeared telling that:

'Length' is not a member of 'UnityEngine.Animation'

Oops, my bad -- I didn't look at how animations are indexed. I just edited my answer to fix this. Oh, and please make this a comment, not another answer.
