Does Gsx now handle all doors automatically ?, lds and Wilco do not have gauges except key commands, so gsx baggage, catering opening the doors will be a huge bonus.
I think you should really read the manual, especially the GSX Editor section.
No, GSX doesn't handle doors automatically, and never will. It would be very risky to do so, because the most complex 3rd party airplanes don't use standard key commands to open them. While *reading* their custom variables, like GSX does now, to know IF a door is open, is very safe, writing and/or using events, would lead to nasty side effects. For example, an airplane might not allow to open a door if there's no electrics, and this might work if the door command is started from the airplane panel, since its own gauges obviously check this. But GSX might force-open it anyway, acting on the variable that controls the visual animations, putting the airplane out of sync with its own animations, and that might cause a big mess.
So, we play safe, and only read variables, to know if a door is open or closed, in order not to have funny-looking situations of men passing through the bulkheads, because the service started without checking the door status.
With the GSX Airplane configuration editor, you can do these two main things:
1) Tell GSX which variables (that can be standard or custom) controls each door, so GSX knows how to check each door open/closed status.
And you can also tell GSX to ignore a door/status, which is useful for those airplanes with fake doors, which are not animated but just painted, you will see "men passing through the bulkheads" in this case, but that's to be expected.
2) Configure the doors actual positions in the 3d space, so vehicles will attach to the correct point.
These two things are what is needed to add support for an airplane in GSX which is not already recognized in its internal database.
