Can't get helos to change altitude

[libbmaster]

Might have broken something - but I don't know what!

The "change alt" button is greyed out. I've already checked the ModernWarfareOrderable - both "can go up" and "can go down" are set to true. Max/min altitudes in the MovementHandeler module are also set to different values.

Is there something else I forgot to check? All of the helicopters in my mod are broken right now, I can't remember what I might have done, and I'd rather not rebuild from scratch...

Check the Position module and the instances in TGameplayTerrain if you did modify those.

You really should have multiple incremental copies of your NDF and a list of your changes to make sure you can revert.

Bah - checked both of those against a backup file, but nothing seems amiss.

My increments weren't incremental enough!


In the meantime, I've observed some very bizarre behavior from helicopters in my mod:
- when deployed over terrain which prevents them from hovering low, they'll always hover low when moved over clear ground.
- when deployed over terrain which allows them to hover low, they'll never hover low - always remaining at max height.

This sounds like I should check TGameplayTerrain again, doesn't it? Nothing was out of the ordinary, and I don't remember editing the file, but I guess I should go back over it when I'm less tired...

Care to share the NDF ? I could take a look.

Absolutely - thank you for the help!

Here's the download: https://github.com/libbmaster/LIBBERATI ... DF_Win.dat

Also: I pulled up the earliest version of my mod I had on hand, and it had this same issue as well - even though my first pass featured nothing but availability changes!

I tested helicopters in the vanilla game and the behavior I mentioned earlier - with helis picking different hover alts based on where they were deployed - that seems to be a thing there too. So the only issue here is that the "change alt" button isn't working.

Just checking back in to say - I discovered the issue!

... It's because I removed the fuel module from the helis.

You can see this bizarre behavior for yourself in vanilla: cargo helicopters have no fuel module, and thus cannot be manually ordered to change altitude!

Might actually try logging this as a bug lol. After all, even command helicopters can change altitude.

I wouldn't have guessed. Thanks for posting your findings!
