Steps To Reproduce
  1. Go prone
  1. Crawl forward really close to the stone hedge and keep crawling toward it's end. If it doesn't happen first time try some different angles at the end of the stone hedge.
  1. At the end soldier will automaticly stand up and thats really not a good idea when trying to keep your head down in a firefight or when trying to approach stealthy.
  1. This "auto stand-up" happens when prone to other objects as well (some rocks etc.) but most notable at the stone hedges.

old bug.. too bad it's still here :(

also happens when crawling over a door threshold.

Same happens if a hill is too steep and you crawl along.

You couldn't usually walk on rocks at all in Arma2, so at least it is better now. But it still needs work. I often get stuck on them and can't walk over them etc.

i hate it when it does that to me

it's a long known problem. We tried fixing it, but there is big issue that steep slopes just make the prone position go totally haywire.
At lest the character just crouches now, instead of standing up. I§t not much, but the best we could do.

Thanks for the update,

Though a bit disappointing to hear I understand not all issues can be solved.
Is it possible though to make the character go to the lowest crouch possible
instead of the normal crouch? that would even be a bit better.

Also that is only about steep slopes I presume, can I guess from that than
that little rocks and walls are fixed regardless of the steep slope problem?

thanks again.

Vespa, thank you for looking at the issue and doing what you could.

Would it be possible to stop player's character movement and allow him, depending on a situation, to either manually crouch-up or crawl back and search for a better way?

It would require a detection system, which wouldn't allow crawling over and onto difficult terrain in question, so that the player would be stopped just before entering the spot and thus wouldn't cause this haywire prone behaviour.

good suggestion armapirx!

Surely armapirx's suggestion is implementable? The system already has logic that detects that the player has crawled onto an 'unacceptable' surface, and changes them to an upright stance. Couldn't that same logic instead move the player back to the position they occupied on the previous frame - i.e. where they just moved from. The effect would be that their movement would be blocked (similar to how bushes and trees currently block your movement), until they raised their stance.

I can't count how many times I have been killed in a firefight because I bumped a stone wall!

BIS please try to fix it in the upcoming DLC! This is a very annoying issue.

Why not just block the moving forward if it gets too steep, instead of making him stand up/crouch.
Got me killed way too many times.

this collision problem should be fixed as soon possible, cause its annoying.

My bet is that they want to refact the whole man class collision to physx, which should fix lot of known issues.

To the devs:
My understanding is this issue is caused by the slope of the roadway geometry LOD of the rock objects being too steep. As with terrain, if the surface is above a certain gradient, the player is forced to stand up.

I assume roadway LOD does not affect bullets. Could a workaround be to fake the roadway geometry of the low rock walls, so that it is flattened out to just below the maximum slope on which the player can be prone, even if it does not reflect the visible geometry?

Have thoroughly and the problem is gone 100%.
@Astaroth, it's resolved. Ticket can be closed.
