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"

NavlinkProxy Navmesh Ledge Stuck

I have a NPC with a very slow maxWalkSpeed (35, it's a duck, so it walks slowly!)

NavlinkProxy won't allow the character off the ledge unless walk speed is a higher value. See screen recording below.


  1. Tried changing colision settings

  2. Changing size of the capsule

  3. Methodically adjusting attrs on Navlinkproxy

  4. Adjusting all related ledge settings on character movement component

The AI is just using simple move to actor at the moment. Same issues with AI move to, and simple move to location. Project template blueprint 3rd person.

I built a simple behavior tree to control the movement. As the character was moving, I noticed that it looked as if it were colliding with the nav proxy link widgets! Is that possible? Seems crazy.

I've confirmed that the 'create box obstacle' is unchecked. Also tried setting Obstacle Area Class to 'none' and 'NavArea_Default'. Also tried setting ObstacleExtent to 0 0 0.

Scaling up the character and setting the NavLinkProxy SnapRadius lower seems to help, but character still seems to collide.

It seems that placing the nav links end widgets below the surface seems to mitigate some of the issues, but suggests that collision is the root issue.
