I think you are not very clear about what GSX really does with an airplane configuration, since it seems you expect GSX to control doors. It doesn't.
In order to be able to open a door on an airplane, ALL the following conditions must be true:
- The airplane model file ( .MDL ) must have the door modeled separately, and animated.
- The door's animation must be linked to some simulation variable. Usually it's one of the 4 standard variables for the Door exits, but sometimes it might be a custom L: Variable. This is also happening inside the .MDL file
- When one of the 4 default door variables is used, the door should be listed in [Exits] section of the aircraft.cfg, indicating its parameters, including the variable used.
What you can do in GSX, is the following:
- You can specify different coordinates for an existing door. This because, door coordinates are only required in the aircraft.cfg for the main exit ( to dock default jetways ), but GSX needs to know precisely where each door is located.
- You can TELL GSX which variable is used to control the door. Not because GSX can control it, but to let GSX KNOW if the door is opened or close, so it can ask you to open it or close when required. Nothing you do in GSX will ever result in GSX controlling the door by itsel.
So, basically, your ability to open a door is totally unrelated to GSX. And you are always supposed to open a door manually ( if the airplane allows it ), GSX will only tell you to do so, and only if the variable you set in GSX is the same as the one used by the airplane.
