FS2004 Making a Bitmap/Element 'slide' slowly

[lionheart]

Hey all,

Im making a gauge item in an HSI. Its a Flight Director. When off, its hidden. When I turn on Flight Director, the two triangles should slowly move up to their position from behind the bezel face.

How might one make a Element 'slide' slowly? I do not want it to blink up there. I want that cool Swiss movement.

Hello Bill

For a 2D gauge:
Perhaps using a timer? Lets say the LVar is named L:Flight_director_timer, seconds, you read time with this variable and depending on its value and -in some way- you set a "case" statement using several images to emulate a "short film". I never done it before; however it's a "working idea".

The wiki for universal timer:

I hope this may enable your wonderful mind to implement a solution.
All the best,
Sergio.

new_filtered_value = k * raw_sensor_value + (1 - k) * old_filtered_value

As stated first, a Lag statement is probably the easiest way.

This is code for an oxygen blinker. This was done before I fully developed the oxygen system on the VC10. So it's a bit crude bit it worked!
I don't use it now.

<Gauge Name="Oxygen Flow Indicator" Version="1.0">
   <Image Name="oxy_flow_indicator_bg3.bmp"/>
   <Element>
      <Position X="15" Y="43"/>
      <Image Name="oxy_flow_indicator3.bmp" Luminous="1"/>
      <Shift>     
        <Value>(L:OxyFlow,number) 0 &gt; if{ 2 (A:Fuel total quantity,gallons) 0 &gt; (A:Indicated Altitude,feet) and
if{ (P:Local time,seconds) 2 % } } els{ (A:Fuel total quantity,gallons) 0 &gt; (L:Cabin_Alt_Ind, number) 10000 &gt; and
if{ (P:Local time,seconds) 2 % } } </Value>
         <Nonlinearity>
            <Item Value="0" X="11" Y="63"/>
            <Item Value="1" X="11" Y="45"/>
            <Item Value="2" X="11" Y="63"/>
         </Nonlinearity>
      </Shift>
   </Element>
   <Element>
      <Position X="0" Y="58"/>
      <Image Name="oxy_flow_indicator_cover3.bmp"/>
   </Element>

Many thanks Vololiberista.

Thanks Tom. That might just do it.

Yep, you said it first.

Thanks!!
