I have a line of code that has deprecated issue in electric and I would like to know what is its better substitute.


=> scan.set_ranges_size((int)(90/0.25));

[Warning:‘void sensor_msgs::LaserScan_<containerallocator>::set_ranges_size(uint32_t) [with ContainerAllocator = std::allocator<void>]’ is deprecated (declared at /opt/ros/electric/stacks/common_msgs/sensor_msgs/msg_gen/cpp/include/ sensor_msgs/LaserScan.h:85)]

P/S: Waiting for @joq's answer for he has done it already. This post is a refactor one.

It would probably work better for others with similar problems to divide this into two separate questions: one for set_ranges_size and another for the btQuaternion constructor.

I've just divided them, could you please cut and paste your previous answer accordingly. Thanks in advance.

@joq: Thanks a lot for the suggesting of dividing them. Yes, it's indeed better for the community.

Use the std::vector resize method directly:


Be careful of that (int) cast. I believe the floating point result will be exact in this example, so truncation should not be an issue. Generally, it is better to round explicitly.
