I have this Unity script that I would like converted to C# if someone much better at scripting than I would be so kind as too.
Also I would like it to use the New UI text and not the On Gui text which I find very difficult to get to line up properly on canvases with multiple camera setups.

just quickly converted it to c#. not sure if it works though
Thanks mikeymike,
I really appreciate that, it gives me a couple of error:

And

oh yeah didnt even notice that. that should fix it.
That fixed the errors but it’s not showing the same stuff in the inspector as the unity script one. So how do I add a UI text to display the Spectrum data?

didnt realise you wanted them to be public variables, fixed now. thats mondays for you
Awesome, that fixed that How do I make it so that I can use a UI text to display the spectrum data…? One of these days that is going to sink into my thick skull lol I know what you mean about Monday’s
Awesome, thanks mikeymike, now it’s perfect
I really appreciate that man. Code is so not my thing, graphics on the other hand, so if you ever need any graphic help you just let me know
