Walls are transparent for arrows and usage

[mztulip]

Describe the bug
I can be killed through rock edge, with sword or arrows.
Also I can go to bed through wall.

Hi, @mztulip !

Generally this case is very similar to #851, and happens when origin of projectile clips into a wall.

Game version: v1.0.3549

Are you sure, about the build? I see .dev on the video. Basically I wonder, if it's before d64004c or after.

If after d64004c, then I might have to disable blackface culling in physics ray-cast procedure...

[mztulip]

I am working on commit abf079e which represents tag opengothic-v1.0.3549.
Therefore it is before d64004c.
I updated it to fa96e0b and it behaves the same.

Well, yeah:

I've changed already existed visibility check, so it account only for direct visibility (and doesn't for other 'senses').

Ideally would like to avoid two-face collision on meshes, since it's known to be a single face in vanilla game.

I updated to f35840e and I still can be killed by arrows. There is small difference that this does not kill me with first shot.
I does not know if this is correlated with this problem, but also there are other situations with interaction through walls.
For example in tunnels where goblins are present they can detect me in neighborhood hole and came to me. It increases difficulty of playing.
Another problem that Npcs can interact with me through walls. Another example is when I am going to port in Khorinis using path and Kardif starts talking to me through wall.(I does not have save. After reloading game, his position was different and this is not working).

If you want I can try to get save from such situation witch forced talk.

talk is handled by PERC_ASSESSPLAYER and should be part of #859

[mztulip]

I updated to latest commit 02dd4de, Bandits are not killing me through wall now.
Hanna is not talking to me until I leave through door.
Bed interaction is still posiible.

Yeah, sorry, I've forgot to mention about interactive objects:
#290 (comment)

Basically "bed" in the game has 2 points from which player can interact with object. If one of those points is sticking-out of building - you get the bug.
I'm planning to do some overhaul for ray-casts and physics for next release, and will look into it as well
