Rotating the player problem

Hi,

I calculated the angle of player and the target's transform and rotate the player to face to the target using the following piece of code.

//player x,y,z
%px = firstWord($player.getTransform());
%py = getWord($player.getTransform(), 1);
%pz = getWord($player.getTransform(), 2);

//target x,y,z
%tx = firstWord(%targetPos);
%ty - getWord(%targetPos, 1);
%tz = getWord(%targetPos, 2);

%eyeVec = VectorNormalize(%px SPC %py SPC %pz);
%targetVec = VectorSub(%tx SPC %ty SPC %tz, %px SPC %py SPC %pz);
%dot = VectorDot(VectorNormalize(%targetVec), %eyeVec);
%rad = mAcos(%dot);
%deg = mRadToDeg(%rad);

//rotate the player to face to the target
$player.setTransform(%px SPC %py SPC %pz SPC "0 0 1" SPC %deg);

But it rotates the player to some false direction.
I don't know is it because of the way I calculated the angle is incorrect or is it the fault of rotating the player.

Your help will be really appreciated.
Thanks in advance.

You do not need the whole transform to rotate the player.
Thus your transform should have a little lag on rotate,you are out of sync in Torque Script transform.
You can use setAimObject() function.

Or better find setForwardvector resource.

Thanks for your reply.
I tried setForwardVector resource.
But it also doesn't make my player to face exactly to the target object.
I'm not sure how can I use setAimObject on player object as I found it's usage only in AIPlayer.

Is there any other better way to rotate and face the player exactly to the target object?
Thanks in advance.
