Need XML Advice (again)

[gavinc]

Hi,
I have run into a number of FS9 models that have an animation I have been unable to get working correctly in P3D (or FSX). This is the animation for things that rotate based on air flowing over them.
The animation works fine on the FS9 model but on the converted model the animation will rotate part way and then jerk back to keyframe 0

The following are a couple of examples of the code that MCX is generating for the animation when I import the FS9 model. Can anyone help me get the animation rotating correctly?

<Code>(A:Airspeed select indicated or true,knots) 26 min     2 /     (L:LastAnemRotation, degrees) +     360 %     d     (&gt;L:LastAnemRotation, degrees)     dgrd</Code>

<Code>(A:Airspeed select indicated or true,knots) 10 min     0.2 /     (L:LastAnemRotation, degrees) +     360 %     d     (&gt;L:LastAnemRotation, degrees)     dgrd</Code>

Thanks
Gavin

I have one question.

Does that FS9 version's animation rotate by key 0- 360 at once ?
I mean the rotation settings are at 0 ..0 degrees 360 ... 360degrees and nothing else ?

If doing at source of GMax level .. FSX animation can't rotate more then 90 degrees at once.
If more then that , won't animate correct.
So can't be sure if it's XML's problem or not.

For checking , just make a simple guage which sets (L:LastAnemRotation, degrees) and test

So has to split in atleast 4 keys
0-90 .. 90 degrees
90-180 .... 90 degrees
180-270 .... 90 degrees
270-360 .... 90 degrees
If me will set at each 10 degrees.

Hi,
thanks for the suggestion.
In MCX the animation has 5 keyframes
0 - 0, 0, 0, 1
25 - 0, 0, 0.707,0.707
50 - 0, 0, 1, 0
75 - 0, 0, 0.707, -0.707
100 - 0, 0, 0, -1

So it looks to me like it is splitting into 4 90 degree rotations.

I have tried setting the animation to anemometer with no success. The animation just freezes.

How about this.
Take out that parts.
Make a animation by the CAD tools like Gmax.
Export as Model.
Merge in one.

Hi,
I extracted the part and re-animated it in FSDS (ancient I know but I can work with it).
I gave it 5 keyframes at 0, 90, 180, 270 and 360 degree rotations and named the animation anemometer. I then compiled the part and attached it back to the model. Thats when I discovered that although I have an <Animation name="anemometer .....> line in my modeldef.xml there is no associated XML code .

Can anyone share this code with me?

thanks
Gavin

Neither of my FSX or P3D modeldef files include any code sections, just headers.

Thanks Tom
I figured it out (finally had the sense to look at some FSX native aircraft with similar animations).
Using the XML editor in MCX and replacing the final dgrd (the one just before </Code> ) with

360 / 100 *

restores the animation.

Yes, dividing the 360 degrees of rotation by 100 (frames) neatly scales the animation properly...
