CLARIFICATION I'm using 2 sections of code to initialise and animate the BRS Chute collapsing on the ground, The first <part> is to check various params for correct display and timing, the second <part> is simple animation code based on an L:Var, along with its correct GUID Entry in to modeldef.xml---------------------------------------------------------The first section should check the neccassary params and "IF" All positive results, become Visible "AND" set the L:Var to 1 The Visibility is working just fine (on its own) and the parts do indeed become visible at the correct time, However... the Moment the L:Var initialisation is added, the VISIBILITY Fails and of course any resulting animation cannot be seen ( if it is indeed initialising! ) Intended actions of the 2 code sectionsPART 1 BRS_COLLAPSE_ACTIVATIONa- SPOILERS DEPLOYED = YESb- AIRSPEED <= 50 MPHc- SIM ON GROUND = YesIF yes to all, Then initialise Both VISIBILITY AND L:VAR (Collapse, bool)

<PartInfo>  <Name>BRS_Collapse_Activation</Name>  <Visibility>   <Parameter>	<Code>	(A:SPOILERS LEFT POSITION, percent) 60 >	(A:AIRSPEED INDICATED, mph) 50 <	and	(A:SIM ON GROUND, Bool) 1 ==	and	if{ 1 (>L:Collapse, bool) } els{ 0 }	</Code>   </Parameter>  </Visibility> </PartInfo>

Part 2 BRS_COLLAPSEModelled Part becomes VISIBLE as its attached to Activation node (Visibility code above)And Animates in accordance to L:Collapse Var

<PartInfo>  <Name>BRS_Collapse</Name>  <AnimLength>100</AnimLength>  <Animation>   <Parameter>	<Code>	(L:Collapse, bool) 100 *</Code>	<Lag>500</Lag>   </Parameter>  </Animation> </PartInfo>

In conlusion, it sounds simple but appears not to want to work regarding initialising the L:Var The visibility section works FINE If I limit it simply to if{ 1 } els{ 0 } but fails when the added L:Var initialisation is added (as below)

if{ 1 (>L:Collapse, bool) } els{ 0 }

OK .. A little "Wierdness" But finally completed the task .. MANY Thanks all round, Avsim forumizers are a valuable asset with this kinda stuff !! Anyway, completed code folows .. Functionality = Switch off fuel when spoiler (BRS) DeployedDiplay BRS chute Deployment (4 stages) Determine HI SPEED Version (Part closed) of BRSSwitch to Collapsing chute when Aircraft touhes downThe deploying/deployed parts are attached to sub node tagged with BRS_DEPLOYED, not displayed until BRS releaseThe Collapsing animation is attatched to sub node BRS_Collapse_Visibility, as above

I would appreciate any comments regading the code, any ways to simplify or condense it would be gratefully recieved. And I hope of course.. its Understandible in my reverse novice notation :)
