I recorded the data in rosbag file of /tf and /scan topics and when i run the gmapping and playback the recorded data from rosbag file nothing changes. And the error is 100% messages dropped.Do i have to record different topic and do i need to do something in the tf topic or not. The scan noe is created by depthimage_to_laserscan and the /scan node is working but the map is not building whats the error. I have implemented same method in gazebo and its working but with p3dx its not working. I have followed from the book programming robots with ros.

Did you follow the tutorial?

I guess the important line for you would be:

Make sure that use_sim_time is set to true before any nodes are started:

rosparam set use_sim_time true
