Make Shooter Game third person (C++)

Hello Greg, thank you so much for your fast response. But the mistake is mine - your code and tutorial works perfect on UE 4.9. I just made it to work without errors on 100%. I published all the six files with changes to save time for your readers. You can attached them in the tutorial.
There is a small problem with the position of the camera when Targeting when click RightMouseButton. If you can please submit a solution.
Best Regards and thank you for your great job.
