FSXA 3d autopilot vspeed knob animation

[Mikmik2012]

Hi I am having can't get the code pasted below to work it is for a 3d autopilot vspeed knob thanks in advance for any help.



<PartInfo>
<Name>knob_autopilot_vs</Name>
<AnimLength>100</AnimLength>
<Animation>
<Parameter>
<Sim>
<Variable>AUTOPILOT VERTICAL HOLD</Variable>
<Units>bool</Units>
<MinValue>0</MinValue>
<MaxValue>100</MaxValue>
<Scale>100</Scale>
</Sim>
</Parameter>
</Animation>
<MouseRect>
<Cursor>Hand</Cursor>
<TooltipID>TOOLTIPTEXT_AUTOPILOT_VSI_INDICATOR_FTMIN</TooltipID>
<MouseFlags>LeftSingle+LeftDrag+Wheel</MouseFlags>
<CallbackJumpDragging>
<XMovement>
<Delta>1</Delta>
<EventIdInc>AP_VS_VAR_INC</EventIdInc>
</XMovement>
</CallbackJumpDragging>
</MouseRect>

You are using the wrong variable!

<Variable>AUTOPILOT VERTICAL HOLD VAR</Variable>
<Units>ft/min</Units>

Hi thanks Bill the numbers move but the knob stays still.

The "units" returned by that variable are ft/min, which is a bit difficult to convert to keyframes!

The simplest approach would be to rewrite the XML script to use a custom L:variable for the knob rotation. Something that is easily convertable to keyframes.

Perhaps something like this example. The custom L:var will control the knob's rotation from -25 to + 25 frames (total animation from frame 0 to frame 50).

You can adjust the numbers however you like to change the rotation. Note that this script allows for both increase and decrease in a single mouse point, which is very important for 3d modeled knobs that can only HAVE one mouse point! Left-click or Mouse Wheel Down for decrease; Right-click or Mouse Wheel Up for increase:

  <PartInfo>
    <Name>Autopilot_VS_knob</Name>
    <AnimLength>50</AnimLength>
    <Animation>
      <Parameter>
        <Code>
          25 (L:Autopilot_VS_knob, number) +
        </Code>
      </Parameter>
    </Animation>
    <MouseRect>
      <Cursor>Hand</Cursor>
      <MouseFlags>LeftSingle+RightSingle+Wheel+DownRepeat</MouseFlags>
      <CallbackCode>
        (M:Event) 'LeftSingle' scmp 0 ==
        (M:Event) 'WheelDown' scmp 0 == or
        if{ (L:Autopilot_VS_knob, enum) -- -25 max (>L:Autopilot_VS_knob, enum) (>K:AP_VS_VAR_DEC) }
        
        (M:Event) 'RightSingle' scmp 0 ==
        (M:Event) 'WheelUp' scmp 0 == or
        if{ (L:Autopilot_VS_knob, enum) ++  25 min (>L:Autopilot_VS_knob, enum) (>K:AP_VS_VAR_INC) }
      </CallbackCode>
    </MouseRect>
  </PartInfo>

I still cant get it to work, I am fairly new to programming.
