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"

Variable name in Structure mangled in Blueprint debugger


When debugging Structures in Blueprint it is not possible to clearly see the values of variables in the struct.

It looks like some GUID is appended to the variable name that makes it hard to read variable name and value.

This is not happening for "regular" variables (without the structure).

If this is a feature then please let me know how to turn it off.

Hi T.Slappy

I am sorry to inform you that this is intended behaviour. The property names are essentially friendly display names we developers can use to easily identify where we are assigning data. At compile time the names have GUIDs appended to them so the engine can distinguish between the labels underneath.

When debugging, I tend to break the struct and print out the data manually, it's a bit more work but as you've pointed out, it's easier to read what's going on. alt text

This is correct answer, but this is nice-to-have feature. I assume large projects are based on C++ and small projects that use Blueprints do not need to distinguish the variables using GUID in tooltips.
