How to stop "monster" from turning towards target during attack

[asd1994]

What I'm trying to do is make a statue actor that does an archvile attack when you step into it's view. However I can't get it to not constantly turn towards the player once it's alerted. I want to get it to where it only ever faces a single direction so the player wouldn't be attacked if they run behind it. Any suggestions? Is this even possible to do? 

 

Here's what I have so far:

 

ACTOR Sentry 1963
{
    Radius 20
    Height 56
    MaxTargetRange 896
    +FLOORCLIP
    +NOTARGET
    +MISSILEMORE
    +MISSILEEVENMORE
    +SOLID
    Obituary "A Sentry spotted %o"
    States
    {
    Spawn:
        SENT A 1 A_Look
        Loop
    See:
        SENT A 1 A_Chase (0,"Missile",CHF_DONTMOVE|CHF_DONTTURN)
        Loop
    Missile:
        SENT A 8 A_VileTarget
        SENT A 48
        SENT A 8 A_VileAttack
        Goto See
    }
}

Both A_VileTarget and A_VileAttack do call A_FaceTarget within them.

 

I would suggest saving old angle into a variable, before the A_VileTarget is called, and restore this angle immidiatly after calling A_VileTarget and A_VileAttack.

That sounds interesting, but how would I do that?

Save into user variable

https://zdoom.org/wiki/User_variable

https://zdoom.org/wiki/A_SetUserVar

 

then restore angle by A_SetAngle.

 

 

Tho this way should prevent it from turning, but it still could attack player that is behind. I don't currently know how to solve it without zscript.

I'm a bit confused. It seems like user variables are for inventory stuff rather than an actor's angle or anything else.
