/**
* na
* Dispatched from a client when its user is controlling a secondary object whose state must be updated.<br>
* <br>
* When `ChildObjectStateMessage` is being sent to the server, it replaces `PlayerStateMessage`.
* The packet frequently gets hidden in a `MultiPacket`, though it is not functionally essential to do that.<br>
* <br>
* Note the lack of position data.
* The secondary object in question is updated in position through another means or is stationary.
* The only concern is the direction the object is facing.
* The angles are relative to the object's normal forward-facing and typically begin tracking at 0, 0 (forward-facing).
* @param object_guid the object being manipulated (controlled)
* @param pitch the angle with respect to the sky and the ground towards which the object is directed;
* an 8-bit unsigned value;
* 0 is perfectly level and forward-facing, wrapping around at 255;
* positive rotation is occurs by rotating downwards from forward-facing
* 0 is perfectly level and forward-facing and mapped to 255;
* positive rotation is downwards from forward-facing;
* between 7 (down) and 231 (up), for 32 angles
* @param yaw the angle with respect to the horizon towards which the object is directed;
* an 8-bit unsigned value;
* 0 is forward-facing, wrapping around at 255;
* positive rotation is clockwise of forward-facing
* an 8-bit unsigned value;
* 0 is forward-facing, wrapping around at 127;
* positive rotation is counter-clockwise of forward-facing;
* full rotation
