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"

Hi JakeOfSpades,

You will want to go into your "All Classes" in the Place mode menu and put a Nav Link Proxy into your game. You can select each end of it directly to show where the AI can jump to/from. Here is some more documentation on them:


You can see it in action in the Content Examples project's NavMesh map.

Let me know if that helps.

Ok I added the Nav Link Proxy into my scene by dragging and dropping in. Now, my AI (how it moves) is done in my NPC Character blueprint/class but the Nav Link Proxy is in my level blueprint, how can I access the Nav Link Proxy (in the Level blueprint) in my npc character blueprint?

TL:DR My Nav Link proxy is in a different blueprint then my Ogre/NPC is, how can I get/set the variable if its another blueprint.

The Nav Link Proxy is just an actor that essentially says 'The Nav Mesh is Connected Here" and allows the AI to walk off of that spot. You would need to set up behavior in the Ogre to detect that it is near an edge and then activate a jump function.

Our AI developers are working on a "Jumpable Location" actor as well, but it will take some time to complete.

I got it, the arrows were not close enough but now I see the connection.
