Character crash after using a NoClipPawn

Hi guys,

I’ll explain the crash, I got a first person character code in c++ and a NoClipPawn script in blueprint, I also got an option in-game where the player can switch in these two states. If I go into NoClipMode and return in character mode, I think (but i’m not sure) the raycast make the editor crash. Usually i’m able too spot my problem in the log crash report but this time I can’t see where it is.

Here’s the log :

Hey chessTrombone-

Looking at the callstack there seems to be an issue with serialization somewhere. Can you post the log file for the crash for more information? Additionally, can you post the class files for the characters as well as the blueprint that uses the NoClipPawn script?

Cheers

Hi ,

I resolved my issue. It was in the checkpoint system, the problem was that when I pass a checkpoint after using the noPawnClip, some info and/or variable was not transferred into the new avatar.

Thx though!!
