Can I run a function in a specific object on the map using the console? Or maybe I can change the variable value using console

You can do reflection kinda. I am trying to figure out how to pass pointers instead of using text.  
But for pointers, using playerControllers UniqueID as a s string, then find the controller by the UID string passed in.

CallRemoteFunction is avaliable with void\*Args as an input, but I am yet to figure that out.

Hope this can help

```
void MyClass::BeginPlay()
{
	Super::BeginPlay();
	FString functionName = "MyTestFuntion";
	FString arg1 = "SomeCoolString";

	FOutputDeviceNull ar;
	const FString command = FString::Printf(TEXT("%s %i %s"), functionName, 34, *arg1);
	CallFunctionByNameWithArguments(*command, ar, this, true);

}

void MyClass::MyTestFuntion(int IntInput, const FString& StringInput)
{
	UE_LOG(LogTemp, Warning, TEXT("%i %s"),IntInput, *StringInput);
}

```

EDIT:: TFunctions are what we are both looking for I think.

Yes, and you don’t need C++ for it. `ke * MyFunction 10` calls a function or custom event on everything in the world that has it, and `set BP_Door_C bLocked false` changes a variable on every instance of that class. You have to know the exact names though, and ke doesn’t show what the function returned.

I made a plugin that makes this easier (full disclosure, it’s mine): [Actor Console | Fab](https://www.fab.com/listings/f34dbf3f-94b8-426d-a8aa-8901f678cb46) , UE 5.6+. There it’s `@Door.bLocked false` or `@Door.Open()` using the name from the Outliner, with autocomplete, and it prints the result.
