As I understand it, unless a creature is either (a) in combat, or (b) within [PC]'s visual range, scripts do not run on a CRE.

 

Is there a definitively known range which qualifies as (b)?  I've seen maximum visual range given as 30, but many ranged weapons have a higher range than this.  Are there different scales used?

 

Has anyone enabled this effect on all CREs in a large, populated area like the Docks district to see whether it still matters on modern hardware?

That assumption is wrong. The reason why it generally works that way is because there's really no reason for it to not work that way. And also there might be other reasons ... like that the random walk is really bad at walking in a tunnel.
The visual range is generally the same for every non opcode #262 affected creature.
Look at the guards that come to the Nashkel's bridge, they walk to and from the bridge past the tavern etc up to the shop and back all on their own, and they start from the middle. So it's same to you as it's for all the creatures.

OK, desert dweller, welcome to the sanity, you are free to search for the limit, it's out there, we drew it in the sand. Ouh, actually it was still snow then.. but anyways.

As far as i know, if an action started before the creature went offscreen, the action is still executed. The problem occurs if you do a quicksave/reload or something like that while the creature is offscreen.

In this case, if the creature doesn't immediately issue an action (for example from OnCreation, or a trigger that's true at the moment of reload), it will be put to sleep until it becomes visible.

So, if you have patrols and such, it is wise to attach this effect onto the creature (or add an equipping item effect)

 

(note: offscreen actually means not seen by any PC in this case).

Thanks.  I can't recall where I got the 30 visual range from.  When I searched for relevant topics, someone posted that the AI didn't run outside of either 24 -or- +10 beyond fog of war.  I might be confusing this with another game I mod.

 

I think I know what to do, but for people that like digging in to issues fully, my intention is to have areas as "alive" as can be.  For an outdoor area, this would include wandering prey animals occassionally stumbling into predators, or roving groups of <bad guys> encountering and fighting guards.  Things like that.  The biggest downside of doing this at all is the out-of-control combat messages in the text window.  If I can't somehow disable that, I'm not sure it's worth implementing.

Hey, if Bioware could do that in Saradush, so can you. Believe in yourself

In the non-EE games, LOS in terms of clearing fog of war is hardcoded to a maximum of 15. Increasing LOS beyond that in non-EE BG2:ToB does the following: (1) allows the PC to see creatures in the fog of war beyond their LOS which looks strange and (2) allows creatures to "see them back".

For the EE games, there is no consistent behavior so I cannot comment too much on that. IWD:EE does allow you to set LOS to much larger ranges via opcode 262.

Hah.  I'm trying to avoid stubborn or clumsy implementation, even if the idea is a good one.

 

@Galactygon

 

What is the relationship between visual range and the other unit of measure used with ranged weapons and spells?  Visual range 15 = ??? range for a spell target?

Visual range of 15 is the default hardcoded value of STAT 147 VISUALRANGE. Range values for .itm/.spl extended headers use another unit of measurement (range of 30 = 15 for STAT 147 VISUALRANGE). Projectile explosions use another unit of measurement (estimate: 60 unit radius = 30 units for range in .spl/.itm extended headers = 15 units for STAT 147 VISUALRANGE).

I am not so familiar in the way this works in the EE games. There is no person who knows this better than Avenger_teambg, perhaps he could provide an explanation for this?

Great info, thanks!  I'm going to try to implement a lot of proximity-based, combat-only auras, so I need to get these measurements solidly in my head.

 

Is there a way to ping a user here?
