[Solved] How to use a variable for transformation target

Unity Engine
1

Hello!

I ran into a problem lately and couldn’t find any solution using google. Sorry if this is a noob questen… but as said, couldn’t find anything anywhere not even a workaround.

In my app I have a dropdownbox which i populate with Gameobjects using tags. If an Object is chosen using the dropdownbox you can rotate it. Now I have a problem with the rotation target:

table.transform.Rotate(direction, degree)

Instead of the using something static “table.” I need this to be more dynamic. I can store the name of the chosen gameobject when I populate the dropdownbox but how can I call it with this variable? In this example NameVariable stores the name of the game object to be rotated.

ContentOfNameVariable.transform.Rotate(direction, degree)

Thank you for your advice!

EDIT: I use the following method to connect my Object with the script:
4464505--409891--upload_2019-4-24_12-26-18.png

Inside the script I declare

    public Text text;
    public GameObject table;
    public GameObject cube;

And the rotation:

    public void rotation(Vector3 direction, float degree)
    {
        table.transform.Rotate(direction, degree);
    }

Keep a copy of the list or array that you use to populate the dropdown’s data with, and use dropdown.value to receive an index back to your list/array. Then you know what object the target of your rotation should be.

does exactly this, you give it the name of the object and it gives you the gameobject with that name. However, I would advise against this approach at runtime due to the heavy memory footprint it causes.

Thank you very much for your replies. I ended up with using dropdown.value.
