In Counter-Strike 2, user commands use Protobuf serialization (CSGOUserCmdPB / CBaseUserCmdPB).

To alter aim angles without jittering the local first-person camera view:

1. Hook CreateMove in client.dll.
2. Access the active CUserCmdBase pointer.
3. Modify pUserCmd->pSubTickContainer->pMessages->view_angles to target head bone angles.
4. Preserve local camera angles in C_CSPlayerPawn->m_angEyeAngles.

The server receives the exact bullet vector while the local client screen remains butter-smooth and jitter-free!

Protobuf sub-tick usercmd manipulation is so much cleaner than the old CS:GO CUserCmd struct patching.

Just remember to normalize angles (-180 <= yaw <= 180 and -89 <= pitch <= 89) to prevent untrusted angle kicks.
