UE2 - UT2kX SetViewTarget problems

forrestmark9 · Nov 22, 2014

Due to this issue being incredibly confusing I require help, basically I want to set the controllers viewtarget to a pawn if they are looking at said pawn when they are dead but currently it doesn't work, as far as I can tell SetViewTraget and ClientSetViewTarget are being called

Here is the code to get a better look

Code:

replication
{
    reliable if( Role < ROLE_Authority )
        PossessZed;
}

state Spectating
{
    function BeginState()
    {
        Super.BeginState();
        if( VSGame(Level.Game)!=None && VSGame(Level.Game).ShouldGoHunt() && !PlayerReplicationInfo.bOnlySpectator )
            GoToState('PreySpec');
    }
}

state PreySpec extends BaseSpectating
{
ignores SwitchWeapon, RestartLevel, ClientRestart, Suicide, ThrowWeapon, NotifyPhysicsVolumeChange, NotifyHeadVolumeChange;
    
    function PossessZed()
    {
        local Pawn P;
        local vector HL,HN;
        local bool bWasSpec;

        if( NextPossessTimer>Level.TimeSeconds )
            return;
        NextPossessTimer = Level.TimeSeconds+0.4f;

        foreach TraceActors(Class'Pawn',P,HL,HN,Location+vector(Rotation)*1000.f,Location)
        {
            if( P != none && P.Health>0 )
            {
                if( Monster(P)!=None )
                {
                    VSGame(Level.Game).PlayerPossess(Self,Monster(P));
                }
                else if( KFPawn(P)!=None )
                {
                    bWasSpec = !bBehindView && ViewTarget != Pawn && ViewTarget != self;
                    SetViewTarget(P);
                    ViewTargetChanged();
                    ClientSetViewTarget(P);
                    if ( ViewTarget == self || bWasSpec )
                        bBehindView = false;
                    else
                        bBehindView = true; //bChaseCam;
                    ClientSetBehindView(bBehindView);  
                }
                return;
            }
        }
        ClientMessage("Can't possess: You must aim at the specimen to possess.");
    }

    exec function Fire( optional float F )
    {
        if( NextPossessTimer<Level.TimeSeconds )
        {
            PossessZed();
            NextPossessTimer = Level.TimeSeconds+0.5f;
        }
    }
    
    exec function AltFire( optional float F )
    {
        if( ViewTarget != self )
            ServerViewSelf();
    }

    function Timer()
    {
        bFrozen = false;
    }

    function BeginState()
    {
        if ( Pawn != None )
        {
            SetLocation(Pawn.Location);
            UnPossess();
        }
        bCollideWorld = true;
        CameraDist = Default.CameraDist;
    }

    function EndState()
    {
        PlayerReplicationInfo.bIsSpectator = false;
        bCollideWorld = false;
    }
    
    function ProcessMove(float DeltaTime, vector NewAccel, eDoubleClickDir DoubleClickMove, rotator DeltaRot)
    {
        bBehindView = false;
        if( ViewTarget!=Self )
            SetViewTarget(Self);
        Acceleration = NewAccel;
        MoveSmooth(SpectateSpeed * Normal(Acceleration) * DeltaTime);
    }
}

1. Put some logs around critical points to know what happens and to check if PC is in state you want to ...
2. In ProcessMove (called each tick) you have (not sure what for ...):

Code:

    function ProcessMove(float DeltaTime, vector NewAccel, eDoubleClickDir DoubleClickMove, rotator DeltaRot)
    {
        bBehindView = false;        [COLOR="Red"]<- switch to FP[/COLOR]
        if( ViewTarget!=Self )
            SetViewTarget(Self);        [COLOR="red"]<- ... switch to view Self[/COLOR]
        Acceleration = NewAccel;
        MoveSmooth(SpectateSpeed * Normal(Acceleration) * DeltaTime);
    }

3. Also, sometimes calling / not calling Super can have unwanted effects.
4. I think, you should consider making some changes in PlayerMove instead ...
