checking a range of values

I am trying to determine WHERE the wheel stops in my other forum post. I have determined a range of values based loosely on Euler sets to tell what pitch roll and yaw stands for every number on the wheel.

I need to compare the final position of the wheel to these values to output what number is showing on the wheel...

How?

I tried to get fancy with select case but no go. I tried a convoluted If then statement but it did not work.

If numbershow < -17 And numbershow > 17 And numberroll=0 Then wheelnumber = 3
If numbershow < 18 And numbershow > 53 And numberroll=0 Then wheelnumber = 2
If numbershow < 54 And numbershow > 90 And numberroll=0 Then wheelnumber = 1

How can I check a range of values?

BTW numbershow id the entityroll$(mesh) value and numberroll is the entityyaw#(mesh) value.

I think you might need to reverse your compares

If numbershow > -17 And numbershow < 17 And numberroll=0 Then wheelnumber = 3
If numbershow > 18 And numbershow < 53 And numberroll=0 Then wheelnumber = 2
If numbershow > 54 And numbershow < 90 And numberroll=0 Then wheelnumber = 1

I think you have your < and > the wrong way round... it shouldn't be possible for numbershow to be less than -17 AND more than 17 simultaneously !!!

How about

if numberroll = 0 then
   Select true
          case ( numbershow > -17 And numbershow < 17)
               wheelnumber = 3
          case ( numbershow > 18 And numbershow < 53)
               wheelnumber = 2

          ... etc

   End Select
EndIf

... and have you thought about what happens when numbershow = 18 ??

Dang! I was trying to use this formula to reconvert the Eulers into one simple angle form of 0 to 360 (or thereabouts) I wasn't entirely successful YET, but I think I am on the right track:

 numbershow=EntityPitch(mesh)
numberroll=EntityRoll(mesh)
numberyaw=EntityYaw(mesh)
wheelnumber = numbershow + numberroll + numberyaw / 90 + 90

Let me try to implement what you have... I did not know you could use parenthesis to exhibit a range value for case!!! @Shambler... My dyslexia strikes again!!! : )

I made a similar mistake a couple of days ago ;)
