Railgun shells ignoring random blocks in their path (phasing shells)

Silent1 shared this bug 17 months ago
Reported

when u fire to heavily protected ships the railgun rounds randomly ignore blocks in their path and hit blocks behind them.

how to replicate

i attached a test target blue print use a ship with at least 8 railguns stacked closely together

fire at the flat surface on top of the test target from 300 - 500 meter after 4- 5 tries u see the phasing of the shells ignoring blocks in their path

here what it looks like

Hello Silent1,


Thank you for contacting us. Unfortunately, I was not able to reproduce it and I was getting a different result from what you are describing. I am attaching a screenshot from my testing where the projectiles damage blocks in clean line and are not ignoring other blocks.


Can you please share your save file with me with your setup so I can test this behavior there?


  • You can access your save files by typing %appdata% into your Windows search bar and you will be redirected to the hidden Roaming folder. After that just follow: \Roaming\SpaceEngineers\Saves. There should be a folder with your SteamID and your saves.
  • Please zip the file and attach it here. If you are having difficulty attaching files you can optionally use Google Drive. When sharing a google drive link please make sure it is set to be downloadable by anyone with the link.

Thank you in advance.


Kind regards,

Hi it happens in pure vanilla too but 3 important thing i discovered it never happens to station target so it needs to be; a ship state. Second it most likely to happen in close range than long range and . And third it won't happen all time u need to do test like at least 4 times to get the phasing as i said its random. I will make a save file as you requested later when i get home.

Please fix this, I had experienced this bug in vanilla conditions on a server as well.

Yeah definitely a issue i have encountered few times, had issue when it would phase trough 5 blocks of heavy armor and hit compartments behind armor. It simply becomes very annoying dealing with it every fight when i need to grind down half of the ship to repair a block that has no entrance hole and is still somehow damaged.

Yes! its a big issue for any combat related action! And repairs are difficult since damage is surrounded by undamaged blocks from all sides.

Furthermore, it spews single-attachment blocks like gyros all across your insides, making it even more of a mess to repair! Fully agreed!

Please don't fix this. Maybe reverse psychology works.

This is a big issue and arguably the worst it's ever been. It happens consistently with larger amounts of railguns hitting a mobile grid simultaneously, where the surface armor's collider is ignored by the projectile which then lands in a non-armor block down the line. Testing a heavy armour cube covered by gyroscopes with 1 layer of heavy on top by firing 12 railguns at each face simultaneously, I got the attached result consistently.


Nerd talk - injecting code into the missile's OnCollisionStart method (as a suffix), I've extracted the detected collision point into a GPS coordinate and determined it is at the base of the gyroscope, as shown in the second attached picture. Sometimes, the sabot hits the gyroscope, sometimes it does not and goes beyond it.


NOTE: All my testing is done in a newly generated Star System in creative mode. Phasing seems more consistent on 3 adjacent faces of the cube, though the particular screenshot I attached shows it happening on 4.
