Problems with Dynamic Scenery

Hi!This time I try to develope my first dynamic scenery. But there are some problems with it, so I ask the pros.I want to design working holdingpoint-lights. The object :Pinzgauer is a vehicle and works fine yet. The object in the :TWYF-comman line contains the groundtexture and the polygones for lights above ground. This also works fine. But I have problems with the red lights.I want that FS monitors the RWY, if in use the lights should appear (:StopF)Here the code:Set( Area15mx 32 )Header( 1 N49:00:00.00 N48:00:00.00 E015:00:00.00 E014:00:00.00 )LatRange( N48:00:00.00 N49:00:00.00 )Area15( N48:15:70.00 N48:12:70.00 E014:14:00.00 E014:07:00.00 N48:15:70.00 N48:12:70.00 E014:14:00.00 E014:07:00.00 ) LatRef( N48:13:19.00 ) CallDLibObj( :Pinzgauer 8 0 0338FC65 003E0BE4 0357CFCF 0375CBB0 ) CallDLibObj( :TWYF 8 0 022A721A 0060AE99 02494584 0375CBB0 ):StopF CallDLibObj( :StoplightsF 8 0 05773AAC 0019F01E 014FBCE3 0375CBB0 ) Exit:Pinzgauer SetPos( N48:13:36.38 E014:11:33.30 298 ) Heading( 170 ) ACS( 1 ) MoveXY( 7 109 20 ) Turn( 2 80 1 ) MoveXY( 30 -74 438 ) Turn( 2 350 1 ) MoveXY( 3 -33 -5 ) Turn( 1 314 1 ) MoveXY( 5 -47 -48 ) Turn( 1 350 1 ) MoveXY( 8 -123 -21 ) Turn( 1 350 1 ) MoveXY( 25 -464 -86 ) Turn( 2 260 1 ) MoveXY( 8 14 -91 ) Turn( 2 170 1 ) MoveXY( 12 180 37 ) Turn( 1 152 1 ) MoveXY( 5 52 25 ) Turn( 1 189 1 ) MoveXY( 5 83 -10 ) Turn( 1 170 1 ) MoveXY( 10 153 31 ) Turn( 2 260 1 ) MoveXY( 20 58 -305 ) Turn( 2 170 1 ) MoveXY( 7 94 18 ) Jump( :Pinzgauer ):TWYF SetPos( N48:13:66.315 E014:11:52.750 298 ) Heading( 158 ) IfObjectInBox( :TWYF N48:13:98.753 E014:11:26.767 298 86.9 1500 30 ) Awaken( :StopF ) Jump( :TWYF ):StoplightsF SetPos( N48:13:66.315 E014:11:52.750 298 ) Heading( 158 ) Jump( :TWYF )End15Could anybody give a little help to me?Yours, Klaus
