Describe the bug
In the recent developmental 7863 Bomb Fragments hit Characters behind Walls.
To Reproduce
Steps to reproduce the behavior:

  1. Make a player with grenades.
  2. Throw active grenade at enemy outside. Close door and get behind wall.
  3. Grenade explodes, Fragments bypass the wall to injure/kill Players and NPCs

Expected behavior
Fragments or Shrapnel should not be able to hit a Character behind a reinforced Concrete Wall or similar. Fragments should be blocked by walls or the walls should be destroyed.

  • OS: Windows 8
  • 0.C-31649-gc0bcd64 (tiles)

There was recently a patch to pretty much eliminate a lot of fragmentation and use light raycasting to calculate the shrapnel that does get launched meaning that if this is a bug, it is in clear conflict with #24171
(I think there are also a couple other pr's that work with fragmentation but this is the one i found)

Need more info, I just attempted to reproduce with a grenade and a house, and took no damage (but was deafened as expected) when a wall was interposed between myself and the grenade.

If you are very close to the bomb but around a corner, the blast can propagate around it and still damage you, that is working as expected.

If you are hit by a blast it will say:
You're caught in the explosion!
If fragments hit you it will say:
You are bit by a large number of bomb fragments...

Maybe it doesn't correctly process the blast radius going around corners and defaults back to the Fragmentation. Note that the windows aren't damaged either.

Can you post screenshots of your options menu or options file?
I positioned myself and the grenade exactly as in your screenshots and took no damage.
Side note, it drew the explosion, which is itself a bug.

I can confirm that this is happening with vehicles as well. This happened when I was driving over a minefield.

Here is my vehicle.

This also occurred when I was attempting to destroy a turret within a lab, and I placed a grenade outside of two metal doors(!) then closed it, and was struck by a lot of shrapnel regardless.

@Xhuis: The original reporter has Z-levels on, do you have them on too?
