Working on the starboard hangar, this is gonna be the launch system I'm don't know if i can use some kind of conditional animation to raise the blast shield when the airplane is on the right opistion, I think with the FS9 tools can be done.
- for user flyable aircraft only by using a BoundingBox in the scenery BGL to check if user aircraft is inside. This doesn't work for AI aircraft. This is the simpliest way.
- for scenery animation (that loops every 56 seconds, unless you figured out how to lengthen animation - I gave up back then). Scenery animations (like windsosk) doesn't care about user aircraft and AI ones. That way, user flyable aircraft and AI should not interact with the launch ramp.
- for user flyable and AI aircraft if you know everything about DLL Modules creation, like FSUIPC. A module can be programmed to locate user and AI planes, then trigger a variable change monitored by a scenery to play a specific animation. That's the hardest way to go.
- for user flyable aircraft only by using a Gauge that monitors user aircraft position and altitude, to be compared with the location and altitude of the take off ramp. That gauge will trigger a variable change monitored by the scenery to play the animation. That's the scaled down version of the module above when - like me - you don't have a clue what memory addresses are used by FS and how to access them through a DLL. Of course, it's pointless since the bounding box version above works well and doesn't need any gauge. The advantage of the gauge above the bounding box is the ability to display custom instruments datas in the cockpit and control aircraft take off roll speed.
However, getting them animated is a nice eye candy, but to be honest, going deep in DLL or Gauge coding to enable the feature for AI is... just insane. Most users won't notice the amount of developpement involved behind, and a few will even fail to correctly install the DLL (without noticing the lack of the animation)
All I can say is the bounding box is OK for me, but good luck if you wanna go further... (I, personnaly, wouldn't)
