You're changing the camera's LookAt before you even attach the camera. Try this:

PHP код:

CMD:objtest(playerid)
{
    new
        Float:coordsfrom[3] = {2056.173828, 794.064025, 35.411571},
        Float:coordsto[3] = {2055.529785, 1132.966064, 40.313831}
    ;
    TogglePlayerControllable(playerid, 0);
    SnowObject[playerid] = CreateDynamicObject(18864, coordsfrom[0], coordsfrom[1], coordsfrom[2], 0, 0, 0, -1, -1, -1, -1);
    AttachCameraToDynamicObject(playerid, SnowObject[playerid]);
    MoveDynamicObject(SnowObject[playerid], coordsto[0], coordsto[1], coordsto[2], 19);
    SetPlayerCameraLookAt(playerid, coordsto[0], coordsto[1], coordsto[2]);
    return 1;
} 


If this just results in your camera looking down or something similar, you might have to use a CAMERA_MOVE as a cut:

PHP код:

SetPlayerCameraLookAt(playerid, coordsto[0], coordsto[1], coordsto[2], CAMERA_MOVE); 


Or alternatively look at InterpolateCameraLookAt.
