Camera pos in player local space.

Working on walk bob camera animations for a regular first-person player class. To control the camera I use:

Code:

Cam.setSpherical(mvCameraPosition, Cam.yaw, Cam.pitch, Cam.roll, Cam.dist);

Problem is that the first parameter of the SetSpherical function which is handling the camera position seems to be affecting the camera's world space position while I'm interested in applying it in player/camera local space.
I wonder if there's a built-in way to do it instead of having to go through matrices and rotating vectors manually.

Not too sure what is the constraint that you are having, cant you just pass your char world pos ?

You could make your own function of setspherical

Code:

Camera& Camera::setSpherical(C VecD &at, Flt yaw, Flt pitch, Flt roll, Flt dist)

{

   T.at   =at;

   T.yaw  =yaw;

   T.pitch=pitch;

   T.roll =roll;

   T.dist =dist;

   return setSpherical();

}

Camera& Camera::setSpherical()

{

   matrix.setPos(0, 0, -dist).rotateZ(-roll).rotateXY(-pitch, -yaw).move(at);

   return T;

}

And have your move at to be taking your local space and add attached pos

From a quick look at that code, I'm guessing that Cam.matrix.setPos() is most likely the answer to my problem. I will give it a shot a bit later. Thanks!

Yeap, passing cam offset.x using Cam.matrix.setPos() got all my problems fixed. Thanks again!
