# 'timer'.

# The second argument is the type of the action,
# which must also match the server:
# TimerAction.

# Having created the client,
# we tell it to wait for the action server to come up,
# which it does by checking for the five advertised topics
# that we saw earlier when testing the server.
# Similar to rospy.wait_for_service(),
# which we used to wait for a service to be ready,
# SimpleActionClient.wait_for_server() will block until
# the server is ready:

goal = TimerGoal()  # Now we create a goal of type TimerGoal
# and fill in the amount of time we want the
goal.time_to_wait = rospy.Duration.from_sec(
    5.0)  # timer to wait, which is five seconds.
client.send_goal(goal)  # Then we send the goal,
# which causes the transmission
# of the goal message to the server:

client.wait_for_result()  # Next, we wait for a result from the server.
# If things are working properly, we expect to
# block here for about five seconds.
