Own Console Variables
Create/Register a console variable
If you want to create a console variable use static TAutoConsoleVariable in a CPP file of your choice. Supported and recommended types are FString, float, and int32.
static TAutoConsoleVariable CVarMyDebugFlag(TEXT("MyDebugFlag"),
0,
TEXT("Well this is just a test debug flag.\n")
TEXT("<=0: off \n")
TEXT(">=1: enable debug something\n"),
ECVF_Cheat);
C++If you want to create a console variable inside a method use IConsoleManager::Get().RegisterConsoleVariable. Supported types are FString, float, and int32.
IConsoleManager::Get().RegisterConsoleVariable(
TEXT("MyDebugFlag"),
0,
TEXT("Well this is just a test debug flag.\n")
TEXT("<=0: off \n") TEXT(">=1: enable debug something\n"),
ECVF_Cheat);
);
C++Getting State of a console variable
To get the state of a variable, just use your registered variable name.
// only needed if you are not in the same cpp file
extern TAutoConsoleVariable CVarMyDebugFlag;
// get the value on the game thread
int32 MyVar = CVarMyDebugFlag.GetValueOnGameThread();
