Unfortunately, you cannot evaluate FRuntimeFloatCurves (or the FRuntimeVectorCurve) in blueprints as of now since the function is not exposed.
If you are able to use C++ however, you can make yourself a function library which exposes them, this is how you evaluate a Runtime Float Curve
.h
/** Evaluates the value of a Runtime Float Curve using the given time. */
UFUNCTION(BlueprintPure, Category = "Math|RuntimeFloatCurve")
static float GetRuntimeFloatCurveValue(const FRuntimeFloatCurve& InCurve, float InTime);
.cpp
float UMyFunctionLibrary::GetRuntimeFloatCurveValue(const FRuntimeFloatCurve& InCurve, float InTime)
{
// Evaluate the curve
return InCurve.GetRichCurveConst()->Eval(InTime);
}
In Blueprints
