i have encountered a problem with this mod that would not let me load up a save though i do have a fair amount of mods installed, ill comment again if i find something more out
Thosperus 22 Dec, 2023 @ 5:04pm 
The mod is broken rn

Ah, the admin mod menu. Hit Alt-F10, then look at the top left of the screen and you should see a Mods menu drop-down like you would from the F2 menu for personal options.

Which tab in the f10 menu?
DraygoKorvan  [author] 19 Mar, 2022 @ 10:38pm 
yes, in the alt+f10 menu

Is there a way to disable or at least decrease wind speeds. Right now they're getting up to 100s of kmph, which makes building and flying very unpleasant. -thx

Awesome mod.
I just had a blast putting a b-52 style plane on the workshop.
Amazed that I could get that thing off the ground with only 8 engines
:se:

Yes, W4sted balances his ship by making sure the CoM is over the main cargo of the ship.
Azriel82 22 Jan, 2022 @ 8:24am 
Right, thanks for responding to my question. I'll just have to be a lot more careful when building ships to get COM where my main ice storage is. That or just not have storage. I suppose I can use just batteries or just hydro tanks, but no H2 gens.
DraygoKorvan  [author] 21 Jan, 2022 @ 10:53am 
Adding/removing blocks is what forces the grid to recalculate the CoD.

It shouldnt be different based on my code, unless the CoM is different.
Azriel82 21 Jan, 2022 @ 10:27am 
Okay, if I change the amount of ice, the COD doesn't change. But if I add a block after adding or removing ice it updates the COD, but COM is unaffected. This still doesn't explain why copy/pasting causes the COD to shift and I don't understand why it would change the COD anyway.
Azriel82 21 Jan, 2022 @ 10:20am 
I've ruled out ice as the cause. I've moved ice around in the inventory and it had no affect on the COD. My planes are built with the cargo containers being mostly at COM, so the COM moves around very little or not at all, and COD is not affected at all.
However, going into creative mode and copy/pasting the plane will cause the COD to shift around. In fact, for every copy the COD is different. If I make 4 copies, the COD will be in 4 different positions, a different position for each copy. Sometimes it's way off, like 3 blocks or more.
These are copies, so everything is exactly the same, except for COD.
DraygoKorvan  [author] 21 Jan, 2022 @ 8:48am 
COD is calculated off of the relative position of every block compared to the center of mass. Are you sure your inventory is staying the same, I see you are using ICE in WWU, which has mass and will shift the COM around. Validate if the COM is shifting.
Azriel82 21 Jan, 2022 @ 8:16am 
I'm having an issue with the mod and I'm wondering if anyone else is having the issue or if this is something I can fix. I spend hours carefully balancing a plane so that it COD and COM line up perfectly, fly it around, it works great, I close the game come back the next day, load the save and the COD has shifted completely (moving backward or forward up to 3 or 4 blocks) and the plane no longer flies correctly. Everything is the same about the plane, blocks, inventory, fuel, even paint job. If I go back to an earlier save and copy and paste the plane before I take it for a flight, the COD stays where it was.
I've had to rebuilt/reload several planes because every time I load back up the COD keeps shifting around. Is this a bug? What is going on here?
(I am using Splitsie's WWU save folder off Steam for this)
DraygoKorvan  [author] 1 Dec, 2021 @ 5:29pm 
Added hints, can be turned off in F2 menu. Added keybind to change lift test direction on the fly.
DraygoKorvan  [author] 29 Nov, 2021 @ 4:27pm 
Added Drag profiles... not much in the UI that lets you know its there, just know that sleeker craft will now have less drag, get to greebling!
Fixed a bug where drag may randomly not apply if grids in world exceed 100 on load until the grid updates.
DraygoKorvan  [author] 14 Nov, 2021 @ 12:25pm 
Adjusted AdvLift systems, Deflection forces now apply to CoD instead of CoM.
DraygoKorvan  [author] 14 Oct, 2021 @ 9:36pm 
Added color options to preferences. Scaled down indicators.
DraygoKorvan  [author] 14 Oct, 2021 @ 3:57pm 
Performance improvements to the draw thread, QoL changes to server settings (now auto save).
DraygoKorvan  [author] 9 Oct, 2021 @ 5:56pm 
Tapped down deflection force a little bit, reworked angular damping to make it less 'springy'
DraygoKorvan  [author] 6 Oct, 2021 @ 8:20pm 
Changed lift a tad, applied ground effect to deflection, increased deflection force.
Zeronut 2 Oct, 2021 @ 2:18pm 
Think I know the answer to this but would a wing sail like this work if you put a hinge sail on it? http://engin1000.pbworks.com/f/1300150048/AC45.jpg or would it have to be one grid?
DraygoKorvan  [author] 10 Sep, 2021 @ 2:14pm 
Few changes to the physics. Further updating ground effect. Ground effect takes in effect ship size so it will be easier to experience ground effect on larger ships. Adjusted the angular damping forces. Angular damping server setting now takes effect.
DraygoKorvan  [author] 3 Sep, 2021 @ 11:08pm 
Dev branch now running a new highly experimental physics change. Angular damping setting no longer has any effect at this moment, instead it has been replaced with a new system that should, I hope feel far better.
DraygoKorvan  [author] 14 Aug, 2021 @ 9:56am 
Updated main branch.
DraygoKorvan  [author] 13 Aug, 2021 @ 5:53pm 
This is the release candidate. Added some more indicators. Red is the direction of lift if the craft in the direction the green line is pointing.

You can change the test direction in the F2 menu (open chat, press f2, underneath the Debug GUI is the test direction.
DraygoKorvan  [author] 13 Aug, 2021 @ 2:57pm 
fixed drag scaling and readjusted water mod integration
DraygoKorvan  [author] 11 Aug, 2021 @ 4:24pm 
Fixed crash when subgrids only had 1 block.
DraygoKorvan  [author] 9 Aug, 2021 @ 10:24pm 
Ground effect added.
DraygoKorvan  [author] 9 Aug, 2021 @ 3:29pm 
Next task, ground effect (with water mod compatibility)
DraygoKorvan  [author] 9 Aug, 2021 @ 3:27pm 
Adjusted COL formula, it will have a higher tolerance so it should be easier to build aircraft just a little bit and keep them stable in flight. Improved accuracy of the CoL Formula as well so less errors can occur.
DraygoKorvan  [author] 6 Aug, 2021 @ 5:09pm 
Fixed Left/Right Oriented grid physics.
DraygoKorvan  [author] 6 Aug, 2021 @ 3:21pm 
Fixed definition problem, adjusted lift coefficient to compensate.
DraygoKorvan  [author] 5 Aug, 2021 @ 7:57pm 
Applied differential lift to normal physics (non-advlift)
DraygoKorvan  [author] 5 Aug, 2021 @ 7:08pm 
Adjusted lift coefficient, rejected lift vector from direction of flight to prevent infinite speedup in some cases.
DraygoKorvan  [author] 2 Aug, 2021 @ 5:38pm 
You can try deleting the modid folder from the workshop to force a redownload 2132786428

You can also join the discord and we can try things there.
Purpleskin 2 Aug, 2021 @ 5:31pm 
yeah config shows, was all set as it should be, just no real drag and no heat damage
DraygoKorvan  [author] 2 Aug, 2021 @ 5:20pm 
Fixed up a small physics issue, reduced deflection drag in advlift mode.
DraygoKorvan  [author] 2 Aug, 2021 @ 12:58pm 
When you load this branch it will not use your config from the main branch, you have to setup your config again.
DraygoKorvan  [author] 2 Aug, 2021 @ 12:51pm 
Do the mod options appear for you?
Purpleskin 2 Aug, 2021 @ 12:27pm 
actually i don't seem to be getting much drag at all, I'm easily hitting 150m/s and no heat damage to speak of.
Purpleskin 2 Aug, 2021 @ 12:23pm 
Interesting, I'm getting none of the rotational forces on this branch Is this intended?
DraygoKorvan  [author] 1 Aug, 2021 @ 11:37pm 
Updated debug options, they now persist. Moved debug pointers to the build gizmo (cubebuilder) only.
DraygoKorvan  [author] 1 Aug, 2021 @ 5:09pm 
Added 8 more armor blocks and 6 glass windows.
DraygoKorvan  [author] 1 Aug, 2021 @ 11:31am 
22 more profiles added (all armor panels, cockpits, and blast door blocks) + Added compatibility with control surfaces.
DraygoKorvan  [author] 31 Jul, 2021 @ 10:27am 
All the profiles are still WIP. Plates are a bit harder for me, gotta think on how to do it.
DraygoKorvan  [author] 31 Jul, 2021 @ 10:26am 
No, just the blocks.
NorthyPark 31 Jul, 2021 @ 4:51am 
Sweet. What about the new armor plates? do they have lift profiles?
DraygoKorvan  [author] 30 Jul, 2021 @ 9:09pm 
Added lift profiles to 24 more armor blocks. All the 2x1x1 blocks should now be added to the lift profiles.
DraygoKorvan  [author] 28 Jul, 2021 @ 7:55pm 
Pushing out more changes! Welcome to 2021.
