Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Get Float Value from Curve in C++


I often use FloatCurve or VectorCurve with a GetFloatValue node to obtain non-linear value based on another float value.

Im using these in tandem with a lot of calculation to generate rotations and positions for meshes and actors in my blueprints.

Is there a way to access a curve asset and do the same thing GetFloatValue does but in C++?

It seems that performance for heavy mathematical calculations would be better in C++ class.

Thanks for any help :o)

Here you go call this in header

 UPROPERTY(EditDefaultsOnly, Category = Curve)
 UCurveFloat* Curve;

Make a curve blueprint in project and assign to this variable and use this in cpp


you can change DeltaSeconds to any value of your curve X-Axis.

It seems that the GetFloatValue function can't be accessed in my own Pawn class now in 4.20.3... Is there any way to solve it?
