unload an object? C#

First go to Edit > Project Settings > Tags And Layers and add a tag named star then select your star in the assets and click on tags and tag it with "star" tag then add the following to your script

 void Update ()
 {
    if ("Change this with your if animation finished bool")
    {
        GameObject.Destroy(GameObject.FindGameObjectWithTag("star"));
    }
 }
 

Thanks Malebakeer!

So I'm kinda noonish at this stuff, what would be the syntax to check if the animation has finished?

Thank you so much for your help!! :)

Cheers
