How to know how to import a message ?
This line of code imports the Int32 message for use in ros from std_msgs.msg import Int32
For someone who is completely new, how am I supposed to know what to type to import the Int32 message? This is all I could find regarding the Int32 message http://docs.ros.org/en/api/std_msgs/h... where does it say that I must type std_msgs.msg import Int32
?
