Bug Gravity Unit Influence/Bug

Bug Report

When building my new ship I discovered an interesting 'bug', the existence of a bubble of gravity in which the gravity unit applies to the player.

My ship has the core relatively close to the front of the ship, not in the very centre of it. As a result I think the game is calculating a radius relative to the core a little less than the total length of the ship and this means that when I activate a gravity unit, as soon as I leave this radius I get booted out of the gravity, regardless of whether or not I have left the dimensions of the ship.

I whipped up a quick test ship with the core at the very front and confirmed the latter, no matter where I put the gravity unit or how long the ship is it always limits the gravity radius to less than the actual length. It doesn't appear to be relative to the gravity unit activated, as shown in the provided screenshots.

The first screenshot is outside the radius, 2nd is just inside and active gravity (as soon as the radius is exited then the player gets "gravity neutralised" message), 3rd is the layout of the ship for reconstructing if you want to test it yourself.

Again this only applies with ships who's core is not at dead centre ,even slightly off centre cores still means that you can fall out of gravity without reaching the outside dimensions of the ship.

EDIT:

Just redid the test after relogging and it comes up with this:

Try verifying all your starmade files if this is indeed singleplayer. If that comes up empty, you're beyond my expertise. I've never seen that before.

All files are good, the only thing I've edited in the settings/server.cfg is the max speed, sector size, and planet size, all of which I can't see having this effect.

Hmmm well I got the 'grapple' error you got, but I have yet to see the gravity error.

Odd, you get the grapple error while still inside the confines of the ship? Even on a fresh install I still get the gravity error, might be a java hiccup perhaps...

I mean I got it immediately after exiting the ship core. There was no gravity systems in play on the ship at all.

Haha, more bugs! If you were to replicate what I screenshotted what do you end up with, do you just fall off the ship or does the gravity drop out before the end?

I drop off the end, like usual. Might be a hiccup with your particular world/java/starmade, but I don't know.

I might have to do some re-installing, I haven't updated java in a while anyway

EDIT: Reinstalling Java did nothing to alleviate the issue, game files are fine so I am completely stumped!

I was about to post a thread about this situation, but I see I'm not alone. I have also been making a ship with the core near the front, and at about 54 blocks back, gravity nullifies automatically on the threshold. Placing additional gravity units yields no results outside the sphere of influence. I was really hoping one more unit would work, as the back part of the crew-able area is only a little further than that...

I'm having the same bug... Ship has the core on very front and the gravity doesn't work on the back of the ship.

It seems to get temporarily fixed when I undock and redock turrets and other entities of the ship, but after a while the back of the ship turns again neutral gravity zone... I have yet to find out what exactly triggers the bug, but it at least seems that it won't occur unless I have something docked into the ship.

Tomssuli · Sep 17, 2015

I made more testing and found that the bug is triggered whenever I add or remove any block of the ship... And is fixed when I (re)dock a smaller ship inside my ship. Still don't know the cause of the bug, but I think it has to do with my core in the nose of the ship. Have to make more ships to be sure...

I've found this bug when docked vertically to a station. I'll use a gravity block to grav to the "down" of the ship (which means my feet are at the galactic north) and as I move towards the rear of my ship to access the hallway to my core, I de-grav and cannot re-align until I walk back to the front of my ship.

(my ship's core is in the front, on a lower level. you have to walk halfway across it and go down a floor to access it.)

I'm having a similar issue. In the enclosed picture, the blue mark is where my core is and the red mark is where the gravity units cease to function. Adding new gravity units seem to have no effect. Grappling doesn't function either; I get the 'aligned to shipname' message, but I am not aligned at all.

Reloading the blueprint appears to fix it temporarily, but when I leave the game and reenter, the problem persists.

Edit: This bug persists on v0.19431.

I HAVE A PRETTY EASY FIX

Ultimately, you need to determine where your entity's center of mass is, with the advanced craft tool you can now find it. then mentally imagine a box the size of your entity centered around your core. Add area triggers on the axis that the entity lacks. Ie, if after you picture the box there is a part of your entity not encompassed by the imaginary box. This is the area your entity will not have gravity, so you need to increase your entity's dimensions without effecting its appearance. Since Area triggers are invisible whilst not in build mode, they are the best choice. Line up the axis of area triggers to increase that dimension accordingly. After some trial and error, granted your main measurement is imaginary, test entering gravity until you are happy your entity is encompassed by the gravity field.

If this is confusing, i may make a video showing how.

Problem though
You are trading turning radius etc for extended gravity

yeah, but this particular ship im using it on is a BFS, if ya know what i mean, I'd rather be able to run around inside my hanger that worry about turn speed. That is a good point though. i had considered this however I like to build for role play.
