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"

Transform a FVector property to Local or World Space

Hi guys.

I have a question regarding some FVectors properties that have the meta = (MakeEditWidget = true) in their properties tag, Basically I'm moving this vector to point into certain position where I want to move the player after he does certain interactions in the level, so I'm looking for a way to transform these vectors to World space or local space so the values actually make sense when working with these values, since the current vector values are tied to it's parent so it's not the real local space or world space. So is there anyway to transform these into World or Local space?

Here are a pair of screenshots:

Thank you.

You can use Compose transform in the kismet library.

Just make a transform for your vector with scale 1 and compose it to your actor world transform. Get the location from the result and you should have your world position.

Hi HarryHighDef.

So this is what I did to transform the information before it's given to the actor, is this what you meant?

 FTransform PortalTransform = GetTransform();
                     FTransform StartLocalToWorld = FTransform(FRotator::ZeroRotator, StartPoint, FVector::OneVector);
                     FTransform MiddleLocalToWorld = FTransform(FRotator::ZeroRotator, MiddlePoint, FVector::OneVector);
                     FTransform EndLocalToWorld = FTransform(FRotator::ZeroRotator, EndPoint, FVector::OneVector);
 
                     StartLocalToWorld = UKismetMathLibrary::ComposeTransforms(PortalTransform, StartLocalToWorld);
                     MiddleLocalToWorld = UKismetMathLibrary::ComposeTransforms(PortalTransform, MiddleLocalToWorld);
                     EndLocalToWorld = UKismetMathLibrary::ComposeTransforms(PortalTransform, EndLocalToWorld);

And in the receiber I got the Location for each of does transformed values. Thank you for the help.
