Bug when using negative numbers in FString.Mid

Development Programming & Scripting

Example :

FString a="hello"
FString b= a.Mid(0, -1));

this returns b =a , where it should return b as an empty string and not equal full string of a.

Hello

Thank you for reporting this issue about using negative numbers in FString::Mid function. I’ve reported this issue in our database under number UE-18756. At moment I’m unsure of way that this will be fixed but I speculate it’ll either be made so that if given a negative number it’ll treat it as a 0 or cause an assert to let user know.

Have a nice day,

Thanks , and good luck!!
