How do I making speedometer for my car game?(car has Physics Behavior)

Hello everyone!

How i can make a speedometer for my game?

my game is same"Hill climb racing".

car doesn't have "car" behavior. it has"physics"!

PLEASE HELP ME!

If you need to know the speed of physics object, use this expression:

round(distance(0,0, object.Physics.VelocityX, object.Physics.VelocityY))

It will give you speed in pixels per second.

Thanks a lot for your helping!

But can you explain it in a Source file?

of course I have to say, i want show the speed by needle in Rated Circle.(I have these shapes)

See this demo:
