MSFD Is she looking at me?
Here is a beautiful script by Horatio that allows to detect whether an Actor looks towards the player:
Begin PCLookAtMe
float fPCX
float fPCY
float fPCAngle
float fdx
float fdy
float fRatio
short sPCLookAtMe
set sPCLookAtMe to 1
;you could probably also add a GetLOS check in here
; however i could never get GetLOS to work properly...although i didn't try very hard
;is PC really far away
if ( GetDistance, Player > 8000 )
set sPCLookAtMe to 0
else
;yay trigonometry
;this basically does a rough calculation of the PCs direction relative
;to the Actor, it only uses 45 degree chunks, though
set fPCX to ( player->GetPos, X )
set fPCY to ( player->GetPos, Y )
set fPCAngle to ( player->GetAngle, Z )
set fdx to GetPos, X
set fdy to GetPos, Y
set fdx to ( fdx - fPCX )
set fdy to ( fdy - fPCY )
set fRatio to ( fdx / fdy )
if ( fdx > 0 )
if ( fdy > 0 )
if ( fRatio > 1 )
if ( fPCAngle < -45 )
set sPCLookAtMe to 0
endif
else
if ( fPCAngle < -90 )
set sPCLookAtMe to 0
endif
if ( fPCAngle > 135 )
set sPCLookAtMe to 0
endif
endif
else
if ( fRatio < -1 )
if ( fPCAngle < 0 )
if ( fPCAngle > -135 )
set sPCLookAtMe to 0
endif
endif
else
if ( fPCAngle < 45 )
if ( fPCAngle > -90 )
set sPCLookAtMe to 0
endif
endif
endif
endif
else
if ( fdy > 0 )
if ( fRatio < -1 )
if ( fPCAngle > 45 )
set sPCLookAtMe to 0
endif
else
if ( fPCAngle > 90 )
set sPCLookAtMe to 0
endif
if ( fPCAngle < -135 )
set sPCLookAtMe to 0
endif
endif
else
if ( fRatio > 1 )
if ( fPCAngle > 0 )
if ( fPCAngle < 135 )
set sPCLookAtMe to 0

endif

if ( fPCAngle > -35 )
if ( fPCAngle < 90 )
set sPCLookAtMe to 0

;do something while the PC is not looking
