When click on a button, play an animator animations through booleans

First you have to call the animator of your game object in this case the panel or the camera with something like:

       public Animator animatorMyObject;

Once you set your variable you can either call it or fill it from the code within start or awake or drag the object to the inspector panel if you make it a public variable.

Once you do that you can access the properties of the animator in your case the boolean with an instruction like:

        animatorMyObject.SetBool("Exact_Name_of_the_boolean_in_animator", false);
        animatorMyObject.SetBool("Exact_Name_of_the_boolean_in_animator", true);
