Is it possible to display the intensity value of a spotlight in the gui?

not sure if i’m asking this question correctly but basically i want to display the intensity value of a specific light in a hud-like display for the player to see. I have no idea how I would begin to do something like this but I was just curious if it was possible.

Yes, you can use Unity UI, since 4.6 to display text: Unity UI Text

And then you will need to do a tiny amount of scripting: Coding for the absolute beginner

You can create your display and a script which holds a reference (public variable) to the UI Text and the light component and then does something like:

using UnityEngine.UI;

public Light light;
public Text text;

void Update()
    text.text = light.intensity.ToString();
