A question regarding tilted gears.

Post by vnysflightclub » Thu Jun 17, 2021 8:26 am

In some of the add on packs that I download and use, some planes like me774d's Boeing 767 has a tilted gear mechanism.
Can someone explain how to add that? I find it realistic and I want to implement this but I don't know how.

The bogies tilt with the variable geometry wing animation. If you set the speed at which the animation triggers to be roughly takeoff/landing speed, it will sort of function properly. Unfortunately there's no other way to do it with the current animation set

There is a another way via trick with a DNM's CLA animation (CLA 22 or CLA 23) which has two two states:
  • Gears touching ground (while aircraft on ground);
  • Gears not touching ground (aircraft in the sky).
But this way tilted gears animation would not be smooth — gears would be "in one moment" tilted up just after take off and tilted down on touch ground (visually it would look little weird, but anyway it should work).

Rotating wheels don't have a boolean state. You can't force them to become a landed sensor

Its possible to combine many rotations origins in parent-child order to get needed result, same way as animation of human legs added in "YSFlight Actors" pack:

Correct, but that doesn't create a boolean state. It creates an oscillating condition
I've already tried every way I could think of to abuse YS into having a weight on wheels animation and have come up empty

The change in oscillation amplitude for the leg movement relies on the linear VGW animation. It can't be done with just rotational motion

Yeah, I mentioned above that a trick with CLA 22 (or CLA 23?) would be not good looking (not a smooth, but as a momentum "click"), but in a situation where VGW animation would be used for some animation at a much higher speed than a take off speed such trick could be used as a workaround for curious reason.
