• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

PB with AI sailplanes:allways sinking!!!

Hello to all and Basys
I need to have ai sailplanes in a soaring mission but they are sinking and became invisibles.
I've tested differents setting , waypoints ..., inside thermals ...
No way to succeed

I've also replaced AI sailplane by flying objects scenery such as generic schweitzer sailplane, it's works but they are flying in the wrong way, tail first :mad::mad:, even with differents setting ??
Have i missed something??
Thank you for your help
Daniel
 
The AI gliders should be able to follow waypoints, but: they don't seem to be supported by thermals thus they decent slowly to the ground. Nothing you can do against it. ;)

I worked around this by either accepting it (they still soar for at least 15 minutes in my mission) or giving them waypoints to the airfield if they get close to the ground.
 
Thank you Horst,so you confirm my problem.
No idea for Scenery Objects flying in the wrong way ?

Sorry I was a bit slow to reply to this...

For 'AI' gliders in missions you have to move around static scenery objects rather than use true AI. The good news is the technique is much more efficient than AI, there are two problems:

1) the standard static glider models in FSX have been modelled 'backwards'

2) you can have the objects move around quite realistically except they don't *bank* in turns. Yaw and pitch are fine.

My 'Austrian Soaring - Day 3' mission includes three (very) low poly glider models that are pointing in the right direction if you want to use those, plus the mission is in plain XML if you want to check how it works:

Note there is now the CumulusX!+sim_probe simconnect modules for FSX which inject ridge and thermal lift into the sim, and for soaring mission development I recommend those (I wrote sim_probe) - having written numerous soaring missions it is impossible to place all the ridge lift manually to compete with the detail sim_probe derives from the landscape.

Hi Folks

B21 -
Bank should be possible.
Have you tried adding a couple of extra waypoints,
then setting the PBH appropriately.

For sailplane 'AI' I had to use a MobileSceneryObject, not an AI Aircraft, and as far as I can tell you can only set bank when you create the object. The mobile scenery can follow a set route of many waypoints (as in Austrian Soaring 3 mission) and turns and pitches pretty well but doesn't bank (i.e. it moves like a truck).

For sailplane AI you'd need a create a new AI aircraft with the model of a sailplane but the performance of a powered aircraft, and no engine noise. Otherwise it won't climb.

The mobilesceneryobject is very efficient - there's no aerodynamic modelling going on - so in theory it would be best if all you want is for an aircraft to follow a fixed path, but the 'no bank' feature is a killer. Plus you have to create a suitable model because the FSX ones fly backwards.

My AS3 mission simulates *50* other gliders flying maybe 40 miles along the same route as the user, but they're still hard to spot. For fun I included an identical mission with jumbo jets and other huge aircraft models replacing the sailplanes, so you can see them more easily. During testing I used the model of a cathedral.

Hi Folks

Ian -
Of course, you are correct.

How about using the stemme motor-glider airfile,
i.e. AI aircraft, rather than MobileSceneryObject.

yeah good point - might be worth a try. The real issue is thermalling - any idea how many waypoints you need to get a good thermal climb simulation? The other thing is efficiency - I learnt from experience you want a *lot* of gliders simulated in a soaring mission because they are damn hard to spot, particularly given the limited viewport of a computer display.

Apart from the 'bank' crapola, the moving scenery object technique has some merit - mainly that you can simulate an entire soaring competition's worth of sailplanes with no framerate impact. If you try this, and to demonstrate how much programming actually goes into the creation of my missions, check out the tool I wrote here:

Mission Waypoint Randomizer
