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"

About FMath::GetMappedRangeValueClamped()

I find the documentation for FMath::GetMappedRangeValueClamped() confusing, as it mentions the following:

 /** For the given Value clamped to the [Input:Range] inclusive, returns the corresponding percentage in [Output:Range] Inclusive. */
 static FORCEINLINE float GetMappedRangeValueClamped(const FVector2D& InputRange, const FVector2D& OutputRange, const float Value)
     const float ClampedPct = Clamp<float>(GetRangePct(InputRange, Value), 0.f, 1.f);
     return GetRangeValue(OutputRange, ClampedPct);

However, the function's body shows that it returns the value of the percentage from OutputRange, which is calculated from the Value within InputRange.

Or am I just misunderstanding the comment?

I consider FMath::GetMappedRangeValueUnclamped()'s documentation to be superior, even though it's poorly capitalized:

 /** Transform the given Value relative to the input range to the Output Range. */
