Hi Gurus,Suppose I want a bitmap what rotates with the bank angle of the aircraft, like something on a wire/string like on the inside rearview mirror seen on cars.I found it very complicated, looking at how some gauges with rotating bitmaps do it, and I am totally clueless on how to start.Can you guide me to the light?Johan

Hi,Work on this one:

<Element><Position X=".." Y=".."/><Image Name="yours.bmp"><Axis X=".." Y=".."/></Image><Rotate><Value>(A:Attitude indicator bank degrees,radians)</Value></Rotate></Element>

<Position X=".." Y=".."/> : position of center of bitmap "yours" somewhere on the panel.<Axis X=".." Y=".."/> : center of rotation of that bitmap.Fette beute!

yes!, works well, I added after studying other gauges / - /like:

<Value>(A:Attitude indicator bank degrees,radians) / - / </Value>

so it swings like a g-force effect.Thanks!

this works well.

Can I use a whole gauge in stead of a bitmap only also to do this or does every gauge item be coded seperatly for this ?

Yes you can!

 

But.....

You need to have the background bitmap in the gauge, not in the panel folder.

Here is the code i use to pull the HUD in the pilot's sight.

 

<Gauge Name="hud" Version="2.0">

<Element>
<Element>
<Position X="0" Y="40"/>
<Visible>(L:hud frame up,bool)</Visible>
<Select>
<Value>(L:capt instr bus AC volts,number) 100 > if{ (L:Flood,enum) (A:LIGHT PANEL,bool) 4 * + } els{ 0 }</Value>
<Case Value="0"><Image Name="hud frame up lv.bmp"/>			   </Case>
<Case Value="1"><Image Name="hud frame up lv.bmp"/>			   </Case>
<Case Value="2"><Image Name="hud frame up lv.bmp"/>			   </Case>
<Case Value="4"><Image Name="hud frame up lv.bmp"/>			   </Case>
<Case Value="5"><Image Name="hud frame up lv.bmp"/>			   </Case>
<Case Value="6"><Image Name="hud frame up lv.bmp" Luminous="Yes"/></Case>
</Select>
</Element>
<Shift>
<Value Minimum="0" Maximum="1">(L:hud frame up,bool)</Value>
<Nonlinearity>
<Item Value="0" X="0" Y=   "0"/>
<Item Value="1" X="0" Y="-120"/>
</Nonlinearity>
<Delay PixelsPerSecond="50"/>
</Shift>
<Shift>
<Value Minimum="0" Maximum="1">(L:hud frame up,bool)</Value>
<Nonlinearity>
<Item Value="0" X=   "0" Y="0"/>
<Item Value="1" X="-120" Y="0"/>
</Nonlinearity>
<Delay PixelsPerSecond="50"/>
</Shift>
</Element>

....
rest code
....

 

After pushing (>L:hud frame up,bool), the frame vanishes in the left upper corner.

 

Mind the 2 elements.

The movement is in the shift parts, ignore the rest, sure you can pull something useful out of it.

what I want to make is 2d version of the compass what swings a little. Your first code let me do this, but to have a gauge doing it is something different.

Your second code does something different I think ?

 

<?xml version="1.0" encoding="utf-8"?>
<Gauge Name="magnetic_compass" Version="1.0">
<Image Name="magnetic_compass_background.bmp"/>
<!-- ======================= Compass Strip ======================= -->
<Element>
	<Position X="21" Y="26"/>
	<MaskImage Name="magnetic_compass_window.bmp">
		<Axis X="32.5" Y="0"/>
	</MaskImage>
	<Image Name="magnetic_compass_strip.bmp">
		<Nonlinearity>
			<Item Value="0" X="294" Y="0"/>
			<Item Value="360" X="50" Y="0"/>
		</Nonlinearity>
	</Image>
	<Shift>
		<Value>(A:Wiskey compass indication degrees,degrees) dnor</Value>
	</Shift>
</Element>
<!-- ======================= Tick Marks ========================= -->
<Element>
	<Position X="51" Y="27"/>
	<Image Name="magnetic_compass_line.bmp"/>
</Element>
<!-- ======================= Shadow ============================= -->
<Element>
	<Position X="0" Y="0"/>
	<Image Name="magnetic_compass_shadow_alpha.bmp" Alpha="Yes"/>
</Element>
<!-- ======================= Highlight ========================== -->
<Element>
	<Position X="0" Y="0"/>
	<Image Name="magnetic_compass_highlight_alpha.bmp" Alpha="Yes"/>
</Element>
<Mouse>
	<Tooltip ID="TOOLTIPTEXT_WHISKEY_COMPASS"/>
</Mouse>
</Gauge>

 

So to let the whole gauge swing left or right I can use:

 

<Gauge Name="Baum" Version="1.0">

 <Element>
<Position X="238" Y="136"/>
	   <Image Name="Baum.bmp">
  <Axis X="160" Y="0"/>
	</Image>
<Rotate>
  <Value>(A:Attitude indicator bank degrees,radians) /-/ </Value>
</Rotate>
<Shift>
  <Value>(A:Attitude indicator pitch degrees:1,degrees) /-/ </Value>
  <Scale Y="0.8"/>
</Shift>
  </Element>
</Gauge>

 

This what I used to swing a wonderbaum in front of the windshield.

 

Now, how to combinde those two ?

 

Since this is higher XML, I probably need your knowledge and skill to do this, since I have no idea where to start on this, if possible.

Hi,

 

Not tested, but try:

 

<?xml version="1.0" encoding="utf-8"?>
