Get FVector from Blueprint tick function

Question

In my BluePrint Tick function for my character, I have a FVector that always changes, and in my C++ component, I want to get this changing FVector and use it in my C++ Tick function, is that possible to do?

Answer 1

To set this in C++, you need to create a UPROPERTY in your C++ code then write a function to set this property.

In your C++ header file:

UPROPERTY(BlueprintReadWrite, Category = "FVectors")
FVector MyCPPVector;

UFUNCTION(BlueprintCallable, Category = "FVectors")
void SetFVector(FVector VectorIn);

And in your cpp file

void SetFVector(FVector VectorIn)
{
    MyCPPVector = VectorIn;
};

Now after you've set the FVector in your Blueprint, call the SetFVector function and plug the BP FVector output into the input of the function.
