Hi,

I remember that there where some problems in earlier J versions from unreal, the problem was as mentioned.in the title from this topic.
My question is what has been done to fix this, are there somewhere documents about this, I would like to know more about this bug.

Thx,


Rubie

227i and 227j have a feature called "enhanced sight check" which allows monsters to see players through transparent walls. It's controlled by flag GameInfo.bAlwaysEnhancedSightCheck which is enabled by default.

227i dedicated servers somehow handle opaque Movers similarly to transparent parts of level geometry, hence monsters may see through Movers when the "enhanced" method is enabled. Although this particular issue was fixed in 227j, the current implementation of "enhanced sight check" may cause weird behavior of monsters in other circumstances (f.e., see https://www.youtube.com/watch?v=0EwtZMs-CbY), so I personally prefer to disable this feature entirely.

So in fact if I  would mutate this command on every map it would be better ?

"Set GameInfo.bAlwaysEnhancedSightCheck=false"

okay will check this out Smiley

You can simply set bAlwaysEnhancedSightCheck to False in your game config file (Unreal.ini or whatever you use as the game ini file).

As far as I remember, UT99 has no anything like "enhanced sight check".

In v436, bots and ScriptedPawns can see through movers on dedicated servers, but this bug differs from the similar one in 227i. In UT, it's not related to some special sight check method for transparent level geometry and the set of affected functions includes Pawn.LineOfSightTo (bots and monsters try to attack the enemy behind a mover as if the mover did not exist at all). My knowledge about UT stuff is very limited; I presume, UT modders could tell much more about this glitch.

I think parts of the ai visibility code uses FastTrace / in 227 eventually the version which checks for transparency. However in stock UE1 engine on dedicated servers the moving brush tracker never gets used, nor the update for it called (which is done during rendering setup), and hence Mover geometry not filtered into level geo and hence nonexistent for FastTrace.

ah okay, ty Han, but I was  thinking like this: if it can be fixed on unreal it maybe can be fixed too for UT  coop servers with a kinda "mod" that fix this transparency from movers, as is realy weird now to see this behavior from the monsters  hehe. I know there are smart guys (womens) over here, so I tought I will post this first on OU and see what happens, maybe Need to move this topic to UT board, sry for this .

Greets,

Rubie
