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 collision sweep , is unreal bug?

struct FHitResult ImpactPoint has this words: @note: In the case of initial overlap (bStartPenetrating=true), ImpactPoint will be the same as Location because there is no meaningful single impact point to report.

when two object overlap , can find the right ImpactPoint .

i try to follow the code , i find this : const bool bInitialOverlap = PHit.hadInitialOverlap(); if (bInitialOverlap && Geom != nullptr) { ConvertOverlappedShapeToImpactHit(World, PHit, StartLoc, EndLoc, OutResult, *Geom, QueryTM, QueryFilter, bReturnPhysMat); return EConvertQueryResult::Valid; } in the function "ConvertOverlappedShapeToImpactHit" :

OutResult.Location = P2UVector(QueryTM.p); OutResult.ImpactPoint = OutResult.Location

the ImpactPoint pos is not the hit positon , when i use "OutResult.ImpactPoint = P2UVector(PHit.position)" relpace to , the ImpactPoint is right.

how can i no change unreal engine code ,use plugin to implement to get the right ImpactPoint .
