Hi all,

have had a Minehit what seems like a bug, or at least I have not heared of it.

What happened:

I have sweeped a Minefield half way by sending my Fleet in the Minefield to one of the Planets in the Minefield.

My Fleet sweeped the minefield as far as they could ( what means sweeped it to the Planet the fleet could easy sweep the whole minefield)

My Fleet needed elsewhere so I moved the Fleet away with Warp 9 from the minefield

Next year I "STAY" at the Planet and hit the Minefield !!! 400 ships died. ( normal damage for a Minefield hit)

Has someone else had this Problem ?

Bug / Feture ? Will do some tests after the game is finished and i get all the files from the Host.

I have no answer to your question.

But very weird you should ask this, since I was just wondering what happens if you move away from the "exact" edge of a minefield. Just like you suggest here: you move in partial & sweep all possible so now sit right on the edge, then you move away at W9.

I had assumed your outside the field and there is zero chance of a hit but your situation suggests not.

Was the angle you moved away at opposite from the approach to the planet? Eg. are you sure didnt slightly cross the field

Hi!

Was the minefield still there or next to the planet, when you moved your fleet?
if it was, it could be the rounding "error" when doing floating-point math with integer coordinates. Confused

@ Crowe

my angle was so that I should not get in the minefields about 10-20°

@ iztok

I also think it is a rounding problem but wants to hear is someone else has had this. It is not that i moved the first time out of a minefield Razz
And it never happened before.

And yes as i sayed the minefield was still there next to the planet as my fleet only sweept to there position ( the planet thy stay )

I just ran some battle sims to test this out a bit myself.

400 ships sweeping into a field, then moving away at W9 (~100+ LY moves to make sure) at various angles between 5-45 degree and each time splitting the Fleet so there was seperate checks.

I can confirm that there is some kind of point blank check.
Each time they was between 1-3 hits out of 400.

I only ran it about ~7 times so not exactly extensive testing but needless to say its enough to put me off trying such a move with a large fleet.

One very strange occurance is worth pointing out though:
I tried the test with speed bump mines also, thinking 3.5% chance x W9 = 14% chance to hit per ship. My thinking was that if each ship has one 1LY test then that should be ~56 hits on average.

That test I ran twice & had only 3 hits each time... doesnt seem to be a standard 1LY check going on to me.
Unless my assumptions about the speedbump are way off.

Hi!

I vagually remember hitting a minefield when flying just beside it. When I did a search on this, I've found some texts about dangers flying next to a minefield, despite the fleet path line is drawn outside the minefield circle. Can't remember where those texts were. RGCS?

Anyway, IIRC it stated that the minefield in rare occasions is calculated larger, than it is "painted" on the screen, so a fleet can still hit it, even if the fleet path is 1 pixel away from the minefield circle.

BR, Iztok

My first question would be

Is a SD involved?

Another question:

Last turn, before the "mishap", how far did the "distance-o-meter" say your fleet was from the center of the minefield? And how wide the minefield itself said it was? Sherlock

The planet's pixel probably counted as still being in the minefield, so you had a 1.5% chance to hit the field immediately upon leaving it. Hence, KABOOM.

Could minefield drift be the issue? I'm sure everyone has seen how minefields that are started over a planet eventually have a center a few light years away from the planet.

Or a cloaked or hidden minelayer is expanding the field?

Hi ,

Minefield drift dont exist. Minfields are centert to the minelayers they lay the mines.
If you have several minelayers in an existing minefiels the minefield will move in the
direction of the stronger minelayer.

No no clokaed mielayers. Even if the laying minefields will come after the movement.

Hi ,

What I could say so far:

The sweeping fleet is not in the minefield ( Exploding minefields will not hit the sweeper )

The chance of hitting is 1-2% per fleet at warp 9 , would be the same as the fleet flys 1 Lj in a minefield

And it depend on the angle the fleet flys away.

what I have tested so far:

- Multiple ships flying away ( always 500 Shaffs tested it 1000 times )
- Multiple angle ( not much tested so i not sure where the save way is )
- SD Minfield explode

ccmaster

PS : Importent to know that this could happen even if it is only a chance of 1-2 %
