Hi ,

I wonder if there is some kind of fix to prevent monsters looking trough movers (doors)
we are also busy to write a Gametype for coop/koth under the UT99 platform, so maybe someone has more knowledge how to write this?
Or is there an existing "MOD" that can be used to resolve this kind of problems?

Greets,

Rubie

That's SeePlayer hard-coded into monster.

Solution:
XC_Engine v20 is able to "Replace" a function from an actor using internal same named ReplaceFunction. Samples are given directly into that engine extension which also is compatible with default player.

Code sounds like:
Code:
ReplaceFunction( class 'ScriptedPawn', Class 'XC_ScriptedPawn', 'SeePlayer', 'SeePlayer' );

And function which I'm using for about 2 years if I'm not mistaking is like this:
Code:
function SeePlayer(Actor SeenPlayer)
{
   local Actor A;
   local vector HitLocation, HitNormal;

   A = TraceShot( HitLocation, HitNormal, SeenPlayer.Location, Location );
   if ( A != None && A == SeenPlayer )
      if ( !SeenPlayer.bHidden && SeenPlayer.bCollideActors && SeenPlayer.Mesh != None && SeenPlayer.DrawType == DT_Mesh )
         if ( SetEnemy(Pawn(SeenPlayer)) )
            LastSeenPos = Enemy.Location;
}
If exist problems you can use adds - wrappers toward Pawn SeenPlayer but I don't think this will get called for non-pawns actors...
XC_ScriptedPawn is an abstract child which is used only for the replaced op code.
