Nope! :( .. If you find any solution, comment here please!
In obj_local_cursor in the Step event I added:..var p = packet_start(packet_t.cursor);
if obj_steam.lobby_is_owner buffer_write_int64(p, user);buffer_write(p, buffer_f32, x);..
This fixed the problem for me :)
Oh i see!, its work for me too, thanks a lot!
