Bug/Problem reports
If you find a problem or something is not working like expected, please post it here.

Not every point is relevant to every problem, but "there's something wrong" is not enough.
- wath happend?
- what was the expected behavior?
- can you describe, step by step what you are doing to reproduce the problem?
- wich part have you used?
- small or large grid?
- Dedicated server or Singleplayer?
- please upload a blueprint/world
- are you using other mods in your world? (please try it with only one mod)
- maybe a designproblem, please try my example ship: HoverEngine Vehicle, same problems or different behavior


Please give me as much information as you can, without this i cant help you.
Thx

@Spartan: I have spawned a small ship, added 7 medium containers, filled them with steel plates. mass ist correct but 87.000kg..How didi you manage to get 650kkg into a small ship? Any mods changing the size? Lets change into Bug reports plse

In reply of this Comment.

I was using 5 large cargo containers full steelplates + the atmo engines weight + the Hover Engines = About 650k kg.

IMPORTANT EDIT:
Tested the same exactly hover vehicle in other world. Works smooth. Seems a corrupted world problem.

- 1x1

- Small grid

- Singleplayer

- If you need me to, but it seems as if it would be happening regardless of ship unless size/mass of ship is a factor here.

- Yeah, nearly 100, but nothing like this so idk what could be messing with it.

- Align to gravity seems off a bit, though possible CoM is an issue, so I guess this is more of a confirmation question than anything. Haven't tested this much, and intitial testing is inconclusive. Wasn't much room on the vehicle to try a lot.

- I made a small maintainence skiff to tool around on the Moon with(Earth's Moon) and noticed it was always leaning a bit to starboard (or to the right when looking at it from behind). I thought it was uneven ground, but I checked on an armor block platform and it still leaned.

If it's CoM, which tbh I'm sorta expecting, it's actually ok cuz it forces some thought into crafts.

That's all really.

Are they evenly placed on each side, or are you only using one?
If so, using 2 might fix it

Using 6, evenly spaced forward, middle, rear.

@Oneil, please check this points:
- activate "debug" and check the sensorpath, maybe you have a block near to the engine and the sensor path checks them as hit in low altitudes (long story, read rechnical background) --> result is that that one is pushing alittle bit more
- all engines have the same settings and are finished?
If none of them, please upload blueprint.

Bug: Ocassionally I can thrust upwards as if using an atmo thruster, even going into space. If I stop climbing, move the mouse a little and get the engines to react, I will start dropping like I'm supposed to, and won't be able to climb again at least for that moment.

I don't believe we should be able to climb so well with these. Holding space should give a very small "jump" effect, but nothing like a real thruster. Great work, love this mod!!

BUG: Small grid hovering monorail on large grid rail. Singleplayer. The rail is made of armor blocks. 2 sideways, one block high. The monorail and the rails do not use other mods (there are other mods in the world so).

Often, after starting the game and in other situations too (not sure exactly when) the monorail is like glued to the rails. I cannot move forward or backward or upward. Sometimes I can shake the monorail sideways using A/D keys and the mouse (it has a gyro). After a minute or so of shaking the monorail suddenly pops up and starts hovering and works as expected.

Another problem arises when I move forward or backward: the monorail becomes unstable and starts wobbling. I don't know if the two problems are linked somehow.

See uploaded world: "Construction" world with stuck hovering monorail.

@ojd,
- to the glue. Downloaded and testet. The Mod is checking from a point under the engine. In your case the Engine lie directtly on the ground and it is not seeing the first surface. Because that it not hovering, also the "normal" thrust is off because for the engine it is high enough. Please try to place one and a half block to the botom so that the engine is not on the ground while turned off.
- to the unstable, i see the vehicle is underpowered, the mod is using the normal behavior of thrusters that damps the vehicle. If there is not enough power, there is no dampening. Add some Power and i think it will be better.

@Takeshi,
Thank you for your hints. I added retractable pedestals and more reactors. Now everything runs smoothly. Luke Skywalker would have loved this mod!

I have this big tilting problem, i have 4 1x1 engines near the 4 corners of my vessel, and i'm using 2 forward and backward atmospheric thrusters and 1 for each left and right, as well as 2 gyroscopes. When i accelerate or decelerate, my ship will either tilt forward or backward pretty far, I'm fairly high off the ground and i actually had the back of my vessel touch the ground before it SNAPPED back to straight, this is so bad that if i didn't compensate so hard using the gyroscopes, i would absolutly flip over. I do have the hover engines set to align with gravety but that is not what is happening AT ALL. very commenly i will be rolled slightly to the right or left or facing slightly above or below center when sitting still, as well as the harsh tilting left and right. I turned on the debug screen and i don't see anything unusual, no block interferance or anything from what i can tell, can someone help me out here?

So it seems to me, since i tried the Idle example on the flat ice and it was perfectly level, but when i tried it on normal everyday terrain that people would be using this on, it didn't level out with the *gravity* , it leveled out with the *terrain underneath it*, it seems that there is a bug that is making the "align with gravity" function of the hover engines, not work at all, (and yes, it is checked on and only on the down facing hover engines) and the hover engines are instead doing their normal function of aligning to whatever terrain is underneath them, which is not what i want, obviously. But that still doesn't explain the horrifieing tilting that is happening when i accelerate or decelerate, that would absolutly cause me to crash if i didn't have thrusters and gyroscopes on, that btw i didn't see in your demonstration video, perhaps thats just how it works when the gravity alignment isn't on down facing engines? Guess i'll find out.

Just want to say though that i do LOVE the consept behind this and how they function when they function xD

Hi Tennohack, thanks for that detailed report, please upload the Bluprint so i can check it my self.
Some points a can say without that:
- Align to gravity is just a small force to help hold botom on botom after jumping, if the ground is sloped, the ship will stay also sloped, if you dont want this, use only one large engine at the center of mass
- forward and backward engines, the are not made for that, so it is possible they dont work as expectet, for example, if the sensorpath isnt hit something, the engine "thinks" it is to high and nothing happend (no force), if it hit, it tries to reach target height, push or pull, if you hit forward, then it push forward
- also possible, on one of your pictures i see thruster near the sensorpath, maybe they hit the own grid, in this case that can lead to wrong moves (fixed in the next version)
Hope that helps for now, please upload the blueprint.
Have fun

Sorry, I forgot to update this. It was a CoM issue. Moved the container and all was good.

Haha sorry i just closed the game to go to bed! I'll upload it first thing when i open 'er up tomorrow.

I kinda have a problem with this, "Align to gravity" makes it sound like they're always going to want to face down, making the vessel level as often as possible, which is exactly what i want unless i'm heading toward an incline at a high speed that would require the vehicle to tilt to match it's incline in order to avoid a crash, but that would be if the ship wouldn't be able to slow down in time otherwise. I would either change the name to make it more intuitive, less misleading, or change the function itself to work something like i've described. I can already keep the ship level during a jump with the two gyroscopes i already need to keep the ship from turning itself over in the first place, and chances are if your making any vehicle with this mod your going to use a gyro, or your not going to be turning much, I think something that activally aligns you with gravity as apposed to the current terrain (temperarally turning off automatically at a speed where the vessle wouldn't be able to stop before hitting whatever is infront of it) would be a much better and more useful replacement for that feature, as well as a much more optional one, something where you would actually want to have it on sometimes and off other times. (a more interactive option i guess?)

You mean the atmospheric thrusters for main propulsion? I'm just doing exactly what i saw in the demonstration video, you had one large atmospheric thruster for forward thrust, and smaller ones on the sides to prevent drift, I only added those because you only ever demonstrated the hover engines like that.. frankly i assumed it was a nessecity, as the hover engines were just a replacement for wheels (in the supported from the ground sense, not the movement and propulsion sense) And on top of that, i've tried to pilot without the thrusters active, i couldn't move 5 feet, even with 2 engines on every side (I usuly use them as collision avoidence "bumpers") it hardly stays upright without the maneuvering thrusters.

yeah the back engines are pretty close, would that have any visual representation on the debug lines or would the debug lines be unchanged by anything that is actually effecting the engines? Are red lines bad? Or just a sign that the engines detect something within range and are applying apposing force? or what
