Compile Time Drastically Increases After Adding Array of FStrings

[xT_H_1x]

After completing “Advanced Cursor Usage In VSCode,” I reran my unreal project and found that the compile time went from averaging about 4 seconds to taking 50 when I changed HiddenWordList.h. I determined that it is due to the large number of FString’s in the array I created inside of the file as when the array only has 1 element it compiles in 4 seconds whereas when it has 1000 it takes the 50. First, I am curious why this is the case, and second, is there a way to prevent this large of a compile time, such as loading the array from a text file that is not compiled? I am new to c++ so I do not know how it specifically handles compilation. My concern here is not so much that it took 50 seconds as it is that I do not understand why.

Thanks!

You can move that to runtime via the solution given here

Slow compile times after adding word list on BullCowGame

Hey everyone, Is it normal to have the compile times skyrocket once the word list gets added to the game? I’m talking about 3 seconds to compile if the list is 10 words long, vs 51 seconds with all 1000 words. CPU utilization (AMD Ryzen 3600X) spikes up to 50% for a second and then lowers to 12% for the rest of the the compile… Unreal seems to be trying to use all available threads, but I guess there isn’t much multi-threading to do on going through a list of words Cheers!
