do you see the command RotatedCall( :B 0 0 %5 )this tells fs to display the object at a rotation on the z axis that will be supplied by variable %5 (which as you can see in the commented variable list is indeed rotation)replace that command with TransformCall( :B 0 0 0 0 0 0 0 0 C74 )which tells the engine to transform the object with a rotation in the z axis as directed by variable C74 which is the wind direction.Good luckBob Bernstein

thanks very much for your quick reply bob!i've stuck in that bit of code and it looks like its working.-n

Just dont forget to have two APIs using C74 variable!Goran BrumenFS Slovenija 2002 teamhttp://slovenia.avsim.net

hi goran,why do i need a second api using the c74 variable? i'm currently using a single windsock api which will display with the correct heading relating to the wind direction. the only problem i have is that if the wind direction changes, the scenery lib has to be reloaded before the windsock reflects this change. would having a second api using c74 help this?this is the code after using

Hi norbrook.It's been found that using a transformcall with the c74 variable to get rotation with the wind won't work right unless there are 2 rotating objects in the visual display.I've used a microscopic ground poly in the same BGL, but in a different Area Structure. This works fine. It uses the same refpoint as the rotating object:; -----------------------;Area( B N42:37:42.00 W088:35:58.80 22 );IfVarRange2( : 0346 2 5 ) ; same as your large rotating objectLayerCall( :_PlaceGP 8 ) Jump( : );:_PlaceGP ; places a tiny triangular groundpoly right under the rotating object.. it needs no color definition... V1 needs to be same as rotating object's;RefPoint( rel :_PlaceGPFail 0.001953125 N42:37:42.00 W088:35:58.80 V1= 400 V2= 2 )TransformCall( :_TinyTriangle 0 0 0 0 0000 0 0000 0 0C74 );:_PlaceGPFailReturn;;:_TinyTriangle;Points( 0-1 0 -1 ; 01 0 -1 ; 10 0 1 ; 2);Poly( a 0 1 2 );;:_TinyTriangleReturnReturn;;EndA; -----------------------This insures the rotation with wind changes... same BGL, different Area statement... same refpoint and v1. You can't see the textureless tiny triangle.Dick
