FYI, 1.07.07 has this build warning:

FMODStudio\Source\FMODStudioEditor\Private\FMODStudioEditorModule.cpp(433): warning C4996: ‘sscanf’: This function or variable may be unsafe. Consider using sscanf\_s instead. To disable deprecation, use \_CRT\_SECURE\_NO\_WARNINGS. See online help for details.

The use of sscanf is perfect safe, but I’ll ifdef in the sscanf\_s version on windows to silence the warning.

I fixed it by changing:

sscanf(TCHAR\_TO\_UTF8(\*StudioVersionString), “Version %x.%x.%x”, &Super, &Major, &Minor);

to:

StudioVersionString.Printf(TEXT(“Version %x.%x.%x”), &Super, &Major, &Minor);

Well, that would fix the warning, but scanf != printf 🙂

I’ve removed the sscanf and changed the code to use the unreal string parsing functionality. The warning should be gone in the next patch release.
