FSXA Engine Switch and Lock

[MijoBerlin]

Hi,
i have a very big problem. I have a two-way engine-switch (Engine_Start) and his lock (lockl).
the switch may only be moved when the lock is open and the lock may go only if the switch is minimum on 1.
I`ve tried many different types of solutions, but all was wrong way.
I hope you can help me.

Here are the codes

two-way-switch

<PartInfo>
        <Name>Switch_Idle1</Name>
        <AnimLength>100</AnimLength>
        <Animation>
            <Parameter>
                <Code>
                    (L:Engine_Start,bool) 50 *
                </Code>
                <Lag>200</Lag>
            </Parameter>
        </Animation>
        <MouseRect>
            <Cursor>Hand</Cursor>
            <HelpID>HELPID_GAUGE_SWITCH_IDLE1</HelpID>
            <TooltipText>ENGINE_SWITCH_1_MODE_MOUSE_L/R</TooltipText>		
            <MouseFlags>LeftSingle+RightSingle</MouseFlags>
        <CallbackCode>
	(M:Event) 'RightSingle' scmp 0 == if{ (L:Engine_Start,bool) -- 0 max (&gt;L:Engine_Start,bool) } (M:Event) 'LeftSingle' scmp 0 == if{ (L:Engine_Start,bool) ++ 2 min (&gt;L:Engine_Start,bool) } } 1 (&gt;L:push_1,enum)
      </CallbackCode>
        </MouseRect>
</PartInfo>

Lock

<Name>switch_idle_riegel_l</Name>
        <AnimLength>50</AnimLength>
        <Animation>
            <Parameter>

                    (L:lockl,bool) 50 *
                </Code>
                <Lag>400</Lag>
            </Parameter>
        </Animation>

        <CallbackCode>
	(L:lockl,bool) ! (&gt;L:lockl,bool) 1 (&gt;L:Button_press,enum)
      </CallbackCode>
        </MouseRect>
</PartInfo>

Boolean values are only TRUE or FALSE indicated by 1 or 0. so the statement ...2 min (>L:Engine_Start,bool)... is not able to put a 2 into (>L:Engine_Start,bool).
There is an extra } in the Idle1 code.
To get the permissions you want wrap the CallbackCode body as indicated in red.

<Name>Switch_Idle1</Name>
          .
          .
          .
          .
        <CallbackCode>
         [COLOR="Red"] (L:lockl,bool) 0 ==
            if{[/COLOR]	(M:Event) 'RightSingle' scmp 0 == 
                  if{ (L:Engine_Start,bool) -- 0 max (&gt;L:Engine_Start,bool) }
               (M:Event) 'LeftSingle' scmp 0 == 
                  if{ (L:Engine_Start,bool) ++ [COLOR="Magenta"]2 min (&gt;L:Engine_Start,bool)[/COLOR] } [COLOR="Magenta"]}[/COLOR] 1 (&gt;L:push_1,enum)
             [COLOR="Red"] }[/COLOR]
         </CallbackCode>

------------------------

<Name>switch_idle_riegel_l</Name>
          .
          .
          .
        <CallbackCode>
        [COLOR="Red"](L:Engine_Start,bool) 1 == 
          if{[/COLOR] (L:lockl,bool) ! (&gt;L:lockl,bool) 1 (&gt;L:Button_press,enum)[COLOR="Red"] }[/COLOR]
        </CallbackCode>

Thanks. Very good. but only goes to half. When switch is on idle and the lock is on, i can`t switch to flight. It would be better to use a different code.

I have no idea of it yet. It`s my first project.

Oddly enough, the "units" of a custom L:var are completely ignored by the sim's XML parsing engine.

There is no effective different between these for example:

1. (L:MyVar,bool)
2. (L:MyVar,enum)
3. (L:MyVar,number)
4. (L:MyVar,fred)
5. (L:MyVar,ginger)
6. (L:MyVar, )

The only requirement is that there must BE a "unit" specified. Note that example #6 is a blank space!

On the other hand, as a programmer by profession, I do stick to "proper" unit designations for my own sanity.

How far does that go?
Would

<Value>100 50 25 10 5 2.5 6 (L:MapZoomStep,FredAstaire) case (&gt;L:MapZoomNM,GingerRogers)</Value>

Give the same result as:

<Value>100 50 25 10 5 2.5 6 (L:MapZoomStep,enum) case (&gt;L:MapZoomNM,enum)</Value>

Tongue in cheek question of course!

No reason why it wouldn't, of course.

As it happens, even (L:MyVariable,unit) will work well...

 

[MijoBerlin]

Give it another kind of code, where one can distinguish between 0, 1 and 2?

It gives codes with 3 ways. unfortunately don`t go. That goes only once. When i will switch to the second position, it doesn`t work.

 

[MijoBerlin]

Are there no other code, where a distinction is made between 0, 1 and 2.

You were already provided an example in Ted Cook's reply.
