• 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.

Turn and slip ball

Hi people,

I'm struggling with a bit of code and wonder if somebody can help out.

I need some code that will work with a MODELLED gauge in FS9.

The old "flat" XML gauge for a turn/slip ball works correctly but I want to make a modelled ball work the same way.

I.E. in a banking turn, the ball rolls with the bank, apply rudder in the direction of the turn and the ball should return to centre glass.

Also, on the ground, the ball should roll in the opposite direction to the rudder input.

Anybody know how to code this correctly for a modelled gauge?

FSX code for SP2 turnslip ball doesn't produce the correct result in FS9

Thanks.:)
 
Hey there Baz,

Not sure if this will help or not...I haven't attempted to do any 3D VC gauge modeling.
For a regular XML gauge, "Turn coordinator ball" is the equivalent to the C "TURN_COORDINATOR_BALL" token. Would that be useable in your part animation?
This token is workable in FS9...check the default Baron CAB for how MS used it.

G'day mate,

Not sure really. When we use the XML as is, but calling for the modelled geometry part, it screws up and will only animate the ball one way or the other. It just won't return the ball on rudder input.:(
 
The XML token should return a value of negative 1 to positive 1, center is zero.
Is your TC ball keyframe animated or ???. If keyframed from 0-XXX, I think you might be able to do some math to get things animated in the range you're looking for. I.E, scale that -1--0--+1 value to 0-100 (or whatever the keyframes are) and use 50 as the center point.

This is about all I remember about animation from when I was dabbling with gmax on the old FDG bird updates...and that was long before we could do all this fancy modeled gauge stuff. :)
 
Thankyou Bill, I will try this too. I have tried so many codes that I am now confused!

Most work the ball OK in a bank but do not recentre the ball when rudder pressure is applied, as it does in the real thing.
