Is the problem in the code or the pawn?

Hi guys,

I'm trying to get the player to face an enemy automatically.. This works:

function AutoTargeting()
{
        //Trace information
        local   Actor     HitActor;
        local   vector    HitLocation;
        local   vector    HitNormal;

        //Position information
        local   vector    TraceDistance;
        local   vector    LookDistance;
        local   Pawn      Target;
        local   Rotator   ViewRotation;
        local   Vector    ViewLocation;
        local   Rotator   r;

	GetPlayerViewPoint(ViewLocation, ViewRotation);

        LookDistance = vector(ViewRotation) * 650;
	TraceDistance = ViewLocation + LookDistance;

        HitActor = Trace( HitLocation, HitNormal, TraceDistance, ViewLocation, true, vect(5,5,5) );

        if ( Pawn(HitActor) == none)
        {
                Return;
        }

        if ( Pawn(HitActor) != none )
        {
                Target = Pawn(HitActor);
        }

        r=Rotator(Target.Location-Pawn.Location);

        if ( Pawn(HitActor) != none)
        {
                SetRotation(r);
        }
        //ClientSetRotation(r);
}

The problem is when I am targeting monsters with different heights. If I make something small the player wont face down at all, he will look straight forward. I've tried changing the collision cylinder and that didn't help. Can anyone tell me whether this is a fault with the code or with the Pawn itself?

Thanks!

There is a difference between where the pawn is rotated to face, and where the pawn is aiming. Have a look at the 'Focus' variable in the Controller class.

Hi,

Thanks for replying. This is in the PlayerController class. Not the AIController class. So 'Focus' does not matter. It is facing the right direction. With normal height monsters it's fine.. With short ones though it just looks straight forwards... I'm trying to figure out if this is because i'm not calling out the rotation right in the code or if I'm missing something on the pawn.

I've checked the collision cylinder, that bits okay I think. But the functions just not centering the smaller enemy pawns correctly...


Can anyone please help?

Bumped! Any ideas?

Humanoid pawns discard pitch/roll iirc when being rotated, at least while in phys_walking. I'd rotate the pawn like you are, but also the playercontroller itself. I *think* that should in turn rotate the camera, which will them make your pawn's animtree aim direction blend kick in, making him look up/down

Hi Jetfire, thanks for the help.. This is actually in my playercontroller code though, not in my custom pawn class.. Was that what you're referring to?

Im trying to figure out how to do exactly the same thing, get a pawn to rotate to face another pawn. So far I haven't been able to figure it out.
