I’m new to programming. It was pretty easy inside of Blue Prints but now I’m trying to look at what certain Vectors I being produced from my CharacterMovementComponent.cpp I have some custom stuff in there and things are not lining up so I would like to Draw the variable data to the screen just like the Print function in Blueprints does.
GEngine->AddOnScreenDebugMessage(-1, 5.0, FColor::Green, FString::FromInt(x)); // x is the variable name
Though you want to display vectors right? Well you’ll want to use floats. So to use floats you’ll want to use this…
GEngine->AddOnScreenDebugMessage(-1, 5.0, FColor::Green, FString::SanitizeFloat(x)); // x is the variable name you want to use.
The nice thing about vectors is you can separate the .X the .Y and the .Z 
Very cool and thanks. Is there a way to do the entire Vector (X,y,Z)? I guess additionally do you know how to append things together? It was nice in BP to just plop a Vector into the Variable and it would auto add the convert node, then I could just append a few things together to get one line of readout. So in my situation I’m trying to compare to Vectors so I know what’s going on in them, it would be nice to have them on one line of Debug with a space inbetween.
GEngine->AddOnScreenDebugMessage(-1, 5.0, FColor::Yellow, FString::SanitizeFloat(GetActorLocation().X) + FString::FString(" “) + FString::SanitizeFloat(GetActorLocation().Y) + FString::FString(” ") + FString::SanitizeFloat(GetActorLocation().Z));
As opposed to normal C and C++ where you simply use the << and >> operators (If you’re working with consoles and streams!) you only need to use the + symbol to append when using various UE4 methods.
This should do the trick, pal.
If you already build something for Blueprint that worked and you want to go to c++ i recommend to rightclick on nodes and “go to definition”… then you can see how the guys from epic are doing it…
Yeah I’ve been doing alot of this The Debug features seem less obvious from in the source. Most other functions are pretty straight forward - Take these types, do this, and return this.
ToString() that vector!
