During this week of programming this project I did run into a few bumps that did slow me down. One of the main issues i faced this week and the most annoying one, was Unreal not saving my blueprints with the updated C++ parent files. When working on the player I wanted to see where the best position would be to store the mesh for first person gameplay, I first stored it under the camera, which did look nice, but eventually ended up storing the mesh under the root so that the mesh doesn't move with the camera. The problem that came with that was for some reason after I changed the location of the mesh and closed Unreal, when I Unreal back up it would store the mesh back in the camera, even though in C++ I had it set to the root file, so I would always have to delete the player blueprint and make a new one, which would fix the issue, but cost me a ton of time. This problem would occur every time I opened unreal editor, until i found a solution to save more time.

I did however find a fix that I didn't know i could do until one of my teammates told me how to do it. The fix was to reload the blueprints after live compiling, which did save some time and place the mesh in the right location, but I still had to do that every time I loaded unreal. I kept doing this until I remembered the ultimate fix that we were taught. The fix that save a lot of time was deleting the Binaries file, DerivedDataCache file, Intermediate file, and the Saved file.

Deleting these files and then generating the visual studio files would completely fix everything and update all the blueprints with their C++ parent files. Not only did this fix my time consuming problem, but it was also the fix I used for other problems. I also did come across another problem where I wrote some code that completely crashed the editor, but when I fixed the code, the editor would still crash, luckily I knew about the deleting these files, which fixed the whole issue. This was the best solution I found to fix most of the problems i get with the editor as it works most of the time.
