Create a Quick Console Command in UE5 using C++

GitHub Repo

In a previous CheatManager post I talked about adding the Exec specifier to a UFUNCTION macro to add a custom console command, but there are alternative methods. One quick alternative technique is to use the FAutoConsoleCommandWithWorldAndArgs function.

There are a lot of examples throughout the codebase and as I searched through I landed on the AssetManager.cpp file for examples. FAutoConsoleCommandWithWorldAndArgs takes four parameters listed below, taken directly from the function's comments inside IConsoleManager.h

• Name — The name of this command (must not be nullptr)
• Help — Help text for this command
• Command — The user function to call when this command is executed
• Flags — Optional flags bitmask

Inside MyCheatManager.cpp I added a very simple command called TestCommand to print out argument strings. I gave it the name MyCheatManager.TestCommand, so when I'm inside the PIE I can use the tilde ~ key to bring up the command prompt and fire my new custom function.

...
static FAutoConsoleCommandWithWorldAndArgs TestCommand(
	TEXT("MyCheatManager.TestCommand"),
	TEXT("Test Command in MyCheatManager"),
	FConsoleCommandWithWorldAndArgsDelegate::CreateStatic([](const TArray<FString>& Params, UWorld* World)
	{
		if (Params.Num() == 0)
		{
			UE_LOG(LogTemp, Log, TEXT("No params listed"));
		}

		for (const FString& Param : Params)
		{
			GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Green, *FString::Printf(TEXT("Param Name: %s"), *Param));
		}
	}),
	ECVF_Cheat
);

After recompiling we can now use our new command in PIE or other debug builds.

I found this to be a very cool way to quickly create a custom console command.
