I couldn’t do blueprints anymore… just too many issues.
My big mission for today is to figure out how to use the methods built into the KismetMathLibrary. More specifically, a dot product of two vectors, Dot_VectorVector.
I have spent the past day trying to figure this out and, while I believe I’ve made some progress, I feel like I’m missing something entirely.
Here’s what I got so far (real simple stuff):
My header:
#pragma once
#include "Object.h"
#include "InwardUtility.generated.h"
UCLASS()
class UInwardUtility : public UObject
{
GENERATED_UCLASS_BODY()
UFUNCTION()
static float PointLineDistance(FVector Point, FVector PlaneOrigin, FVector PlaneNormal);
};
My cpp:
#include "Inward.h"
#include "InwardUtility.h"
#include "KismetMathLibrary.h"
UInwardUtility::UInwardUtility(const class FPostConstructInitializeProperties& PCIP)
: Super(PCIP)
{
}
static float PointLineDistance(FVector Point, FVector PlaneOrigin, FVector PlaneNormal)
{
return UKismetMathLibrary::Dot_VectorVector(UKismetMathLibrary::Subtract_VectorVector(Point, PlaneOrigin), PlaneNormal);
}
My current error:
1>Inward.generated.cpp.obj : error LNK2019: unresolved external symbol "public: static float __cdecl UInwardUtility::PointLineDistance(class FVector,class FVector,class FVector)" (?PointLineDistance@UInwardUtility@@SAMVFVector@@00@Z) referenced in function "public: void __cdecl UInwardUtility::execPointLineDistance(struct FFrame &,void * const)" (?execPointLineDistance@UInwardUtility@@QEAAXAEAUFFrame@@QEAX@Z)

If anyone has any ideas, I really appreciate it and sorry if this is way stupid.
