ZDoom

No. It would be a faulty/buggy visibility check if it did that.

How would that work if the sector is bigger than the actor can see? Would it end up counting something the actor can't actually see from where he is?

That sounds like you're trying to hack in an occlusion system. I'd want to look at doing that properly (and exclusively via UDMF) if I were to try it.

Hey GooberMan, if you ever get that code working... just wondering, would it help in situations with large, wide open world-style maps with few 1-sided lines to block the view?

That'd be great. This is something nobody here has good experience with and a lot of interesting features had to be 'no'd.

Sounds like there could be some very good speed wins there by optimising that. Especially if agressive use of SIMD is employed. It should come down to nothing more than a series of dot products.

Really need to get some clearance to do some ZDoom code from my employer. I've done visibility systems before (that needed to run on a PS2).

That alone would cost more than just checking all actors of the requested species.

Alright, let me spell out for you what I mean then.

[list][*]Actor has a cone of sight
[*]Actor collects sectors visible in cone of sight
[*]Actor parses those sector's actors to see if a species is in its line of sight[/list]

It might even be more efficient to only consider subsectors, but that sounds like too fine grained a place to store an actor list.

Speaking of line of sight: monsters have a 180° FOV when asleep, 360° FOV when woken up. (Monsters with the LOOKALLAROUND flag have 360° FOV even when asleep.)

Really? You mean there's no way to sort actors by sector?

I don't think so.

This can't be done efficiently because you have to perform a sight check with every single actor of the species. This can cause serious performance issues in some scenarios.

Sorry for bumping this (again, I didn't see that it was bumped once, hehe). I just want to ask if this suggestion has a chance of being implemented. :)

I am using Thing_Hate, but I forgot to specify that I need them to be counted as kills towards the player (which +friendly removes).

Using [wiki]Thing_Hate[/wiki] will override friendliness if that is any use to you.
