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"

Cannot create comment box from selected nodes in Behavior Trees

Although there is an option in the right-click context menu within a Behavior Tree for "Create Comment from Selection" when multiple nodes are selected, clicking this option does not create a Comment Box. Tested by selecting a variety of combinations of types of nodes, but none result in creating a Comment Box.

Also successfully crashed the editor while testing by attempting to copy/paste a Comment Box from a Blueprint into a Behavior Tree. ;) Bug was submitted. (First line from callstack: UE4Editor_BehaviorTreeEditor!UBehaviorTreeGraph::UpdateAsset() [d:\build++ue4+release-4.12+compile\sync\engine\source\editor\behaviortreeeditor\private\behaviortreegraph.cpp:109].)

Minor issues since they only deal with usability/organization and not Behavior Tree functionality, but worth reporting. As a general feature request it would be nice to have some of the other organization controls that exist in the Blueprints in addition to the Comment Boxes, such as distribution and alignment of nodes.

Product Version: UE 4.12

I have been able to reproduce your crash, and have entered a bug report, UE-31781. I have also reproduced your issue with the Create Comment from Selection option. and have entered UE-31786.

I have also entered a feature request for the ability to use blueprint organization features in behavior trees, UE-31784.

Thank you for your reports and suggestion.

Have a great day

Hey Sean,

I am using Unreal 4.13 and can't get the "Create Comment from Selection" option to work in the Behavior Tree. Has this feature been silently removed without removing the context menu option?

Hey CharlieVolpe,

Here is a link to the public tracker so you can keep an eye on the issue: https://issues.unrealengine.com/issue/UE-31786

Has the option been removed? It doesn't say on the tracker and it's nowhere to be found in the Editor.

Hi quimnuss,

I've checked on this in 4.20 and the 4.21 Preview, and it appears to be working as expected:

alt text

Make sure that you're right-clicking on one of the BT nodes, not in empty space on the graph.

Let me know if that helps.

Ahà! That was it, I was pressing C as usual and also right-clicking on the void or something. Maybe it should be consistent with the how comments in blueprint are made. But thanks! Solved my issue.
