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"

[Closed] Crash in ANavLinkProxy::GetComponentsBoundingBox

If you turn a NavLinkProxy into a blueprint, and then compile it, you'll crash in ANavLinkProxy::GetComponentsBoundingBox because SmartLinkComp is NULL.

I reproduced this in a clean 4.13.

  1. Created new 1st person project called "NavLinkCrash"

  2. Place a navmesh bounds volume

  3. In "search classes" bar picked "Nav Link Proxy", dragged it into level (I tried to put it in the bounds volume - but I don't think it matters)

  4. Clicked "Blueprint/Add Script" button to create a blueprint for it (left it with default name)

  5. Clicked "compile" for that blueprint - crash.

Appears to happen because when the blueprint is compiled and it replaces the object via "CopyPropertiesForUnrelatedObjects", the SmartLinkComp doesn't get set in FFindInstanceReferenceSubobjectHelper::Duplicate, so it converts to NULL afterwards.

The object is clearly intended to have a SmartLinkComp, so I don't think guarding the "if" statement is sufficient, but I don't know what should be done about it.
