CAMERA CONTROLS - Sit Camera Script Help

[Syaoran Nyoki]

Hello. This should be an easy one for a master. 

I am attempting to create a script that will when an avatar is seated in a chair the camera will look squarely at a presentation screen, no matter which seat the avatar is sitting in. The problem is I can't seem to tell the camera which way is forward. For example - My avatar is sitting in a chair facing the screen. I hit ESC and the camera position is correct - except it is looking at a point 90 to my right. I can't seem to get past this one. Please help me.

 

Here is my script.

 

vector focus = <129,129,455>;
vector pos = <126,129,455>;

lookAtMe(integer perms)
{
    if(perms & PERMISSION_CONTROL_CAMERA)
    {
        vector camPos = pos;
        vector camFocus = focus;
        llClearCameraParams();
        llSetCameraParams([
            CAMERA_ACTIVE, 1,
            CAMERA_FOCUS, camFocus,
            CAMERA_FOCUS_LOCKED, TRUE,
            CAMERA_POSITION, camPos,
            CAMERA_POSITION_LOCKED, TRUE
                ]);
    }
}

default
{
    state_entry()
    {
        llSitTarget(<-0.3,0,0.3>, llEuler2Rot(<0,0,180>*DEG_TO_RAD));
    }
    changed(integer change)
    {
        if(change & CHANGED_LINK)
        {
            key agent = llAvatarOnSitTarget();

            if(agent)
            {
                llRequestPermissions(llAvatarOnSitTarget(), PERMISSION_CONTROL_CAMERA);
            }
        }
    }
    run_time_permissions(integer perms)
    {
        lookAtMe(perms);
    }

}

Forward in your example is: fwd=focus-pos = <129,129,455> - <126,129,455> = <3,0,0>

What I am saying is that you must determine focus and pos in a way so that forward is right.
I hope this answers your question:smileyhappy:

Another thing, why do you hit ESC?
ESC releases the camera and makes it resume default and that you can't control with focus and pos settings

Thanks Dora. You really helped me out.  I realized the problem was between keyboard and chair. It worked fine I just had the wrong values in the wrong axis. Thanks for your time.

That's not my experience, which is that if the user's cam is alt-zoomed or -panned away from the default cam position and orientation, they must hit Esc for the scripted cam control to have effect.  

I think that's what the wiki is trying to say, with "Scripted camera parameters will not set for the agent if the last controls they used were their camera controls. Manual camera control will override set parameters too."  The old lslwiki had a more extensive write-up about camera modes.

You are absolutely right and I am wrong
Forget what I said about ESC and the camera
