Compiling tutorial triggers a UE4Editor.exe breakpoint

Hi Guys,

finally found some time to learn some more Unreal Engine 4.

I did the “Introduction to UE4 Programming” tutorial series on youtube. The whole problem occured when writing the code of the videos 13 and 14.

I wrote to code of video 14 up until the end. When compiling I get an “error” that tells me “UE4Editor.exe has triggered a breakpoint.”

Debug output shows lines like these:

All those files which are supposedly missing are actually there, I’ve searched for them in the given folder. There doesn’t seem to be a syntax error since building works fine. However I can not start the compiled stuff.

I’ve watched both videos twice to make sure, that I get all the code correct, which seems to be the case. But its kinda hard to tell since Visual Studios code recognition and intelli sence features suck in compination with UE4 programming.

Anyone got an idea how to solve this?

P.S.: I should mention, that I am using the Version 4.4.0. You might have seen that in the debug outputlog. :slight_smile:

Well, I don’t know what I did but after doing all over again the code runs finde. I have no clue why this happend :confused:
