Cab/Panel2.cfg - any way of achieving a "Radial LED" digital gauge ?

Hi, wondering if there is some recommended approach or in-built OpenBVE Panel2.cfg support for a sort of "radial digital" in-cab gauge whereby an outer ring of LEDs illuminates according to an underlying value such as speed? 

This is almost like a hybrid between the existing [digital gauge] and [needle] elements, insofar as it's basically extending what I understand to be the straight-line capabilities of the former to incorporate the angular  / radial aspects of the latter.

Representative image below - basically the outer ring of LEDs on the LHS image is closest to what I mean.  

You may want to take a look at the Keio class 8000 EMU, which have a combined type of speedometer:

Thanks for the quick reply - definitely looks like what I'm after.  Unfortunately the link you include mentions in the download section 
" The creator's website has disappeared from the Internet."
Tried googling around a bit with no luck , but will continue looking - thanks again!

That is true, but if you look one line below the line you quoted, you'll find
"To download from this website: OpenBVE train package ver. 1.0.0.0"

Oh whoops, thanks very much - I misread that as downloading OpenBVE v1.0.0.0 itself! I will have a look, cheers  

Interesting - so it appears the original panel.cfg supports this style of indicator through [Speedometer] section of Type=1

This leads me to be a bit confused about OpenBVE panel.cfg vs panel2.cfg - the documentation states 

"The panel.cfg has been superseded by the panel2.cfg. You can achieve the full functionality of the panel.cfg and more by using the panel2.cfg instead."

... this implies the panel.cfg functionality is supported as a subset of panel2.cfg processing, but stepping through the OpenBVE source (with only a limited understanding of the codebase) suggests to me that this command is not processed if it's present in panel2.cfg - and I can't see any other panel2.cfg commands which support a similar gauge style.

I'll continue to play around in case I'm missing something, and also test customized variations of [speedometer] in panel.cfg (noting it appears to work - although with minor visual artefacts - for the Keio class 8000)

There is something called DigitalGauge. That is the designed method of implementing such gauges. Is that the thing you are looking for?

It creates a solid-color square showing a radial of it. You can draw all the LEDs in your background and then use it to "block out" the LED lights you are willing to extinguish.

Thank you both for your help - I finally understood how this is meant to be used in combination with an overlay with transparency (via a [PilotLamp] section)to block out the LED light section you don't want - as you were saying zbx1425. 

So to summarize, I get good results using this combination
- [PilotLamp] section for the "cover" 
- [DigitalGauge] section linked to the speedo

Code:

[PilotLamp]
Subject = true
Location = 503,484
DaytimeImage = speedocover.bmp
NighttimeImage = speedocover.bmp
TransparentColor = #0000FF
Layer = 3

[DigitalGauge]
Subject = kmph
Location = 544, 529
Color = #9d0000
Radius = 40
InitialAngle = 120
LastAngle = -120
Minimum = 120
Maximum = 0
Step = 5
Layer = 2

Glad to see you've got it all figured out. I should've told you the "overlay with transparency" thing earlier... Good day!

BTW, the way you are doing does not create a gauge with the style of individual LED little lamps.
It is designed to work like this:
1) Draw a ring with all LED bulbs illuminated in the background
2) Use DigitalGauge with InitialAngle less then LastAngle and a black color, to "block out" the LED bulbs that are not supposed to illuminate
3) And lay another PilotLamp cover on top of the DigitalGauge for the face
In that way you can display the "shape" of the round LED bulbs instead of just solid color.

Ahh yes I see, thanks for further explaining that approach.

I was thinking another strategy for achieving the look of "individual" looking LED segments would be just to modify the 'cover' being used in the [PilotLamp] section to include small areas of separation from one segment to the next.

Anyway in the short term (without any of the above), this is the look I have  - still working on transparency and size for the digital numbers

That is also an idea.

(Sigh) When you try to combine taken photos and drawn images together they always are not fitting well...
