Generating getter and setter methods for simple custom message

edit

I need to create a custom message for a PTZ camera so I can post the pan, tilt and zoom values to a topic. The problem is that I can't generate any access methods to change them. My message is defined like this:

std_msgs/Header header
float32 pan
float32 tilt
float32 zoom

Below is the generated header, but includes no methods for setting any of my defined values.
