[Emmet_]

It is a SA-MP related function and cannot be altered. However, one solution is to set the player's camera to face a black screen (and then using SetCameraBehindPlayer when removing the blindfold):

pawn Code:

SetPlayerCameraPos(targetid, -833.5241, -1358.8575, 86.9054);
SetPlayerCameraLookAt(targetid, -833.5241, -1358.8575, 0.0000);
