When soldiers use walls as cover they do not take account of whether they transparent (wire fences) or solid like brick. This can make them very vulnerable.

Related to Bug 1709?

Updated by DomProgZ over 7 years ago

The title should have been "AI use wire fences as cover"

It maybe related to bug #1709, but that depends on how Arma 2 is implemented.

#1709 is indeed related. The fire geometry will stop bullets and the AI uses it for targeting and visibility checks.

Updated by DomProgZ over 7 years ago

I did a future check on this today. The wire fences in this example do allow bullets to pass through them and the AI to see through them as well. However I think what I meant was AI stands up behind wire fences which is bad if they are under fire which may just be a current limitation of the AI. The other 4 problems that I posted #3241, #3240, #3239 and #3238 probably are simpler to solve.
AI control is almost infinitely complex computationally in general and all we can really hope for is that the AI more effective statically, given how slow CPUs still are.
I’m glad Arma 2 is loads better than Arma 1 which was very good anyway.
I think this problem particular I posted is quite minor really and was probably too picky.
Sorry this example is for Chernarus, which has masses of fences.

If I interpret this right, according to the mission attached, after 2-3 minutes I saw them standing behind the fence like in the attached screenshot. Looks like they feel safe there... :)

The cover system was changed so this shouldn't be such an issue at the moment.

No feedback unfortunately. Reopen if still problematic.

I can confirm, that this bug is still actual.

Still true in latest CO.

However personally I see it OK, as humans do it too and better than nothing.
