Tab Targeting

Unity Engine
1

Good Evening All!

I’ve got some code here that is not having any compiler errors, but it’s not functioning correctly. I am able to tab target (somewhat reliably), however, my text stating my distance from the target will either function if I manually drag my target into the inspector, or give me a “AnotherTransform has not been assigned”. This makes sense as I can physically see it empty, but I’ve tried to give it a null setting, I’ve tried to wait until I can tab target, and none of them seem to work unless I put a specific object in there first. So I get tab targeting, but my distance is always to the object I placed in there in the inspector. From “private void ShowSelectedTarget” down is really where I think the issue is that I can’t seem to mix around any which way with any success. Any and all help would be most appreciated!

    public Transform selectedTarget;
    public string targetTag = "Targetable";

Anybody have any ideas? Do I need to provide more information? Narrow something down? Please let me know what you need in order to help my helplessness
