AI not following in Behavior Tree Quick Start

I’m following the tutorial in the doc ([link here][1]) but the bot does not move at all. I noticed two things that are weird:

  1. I get a warning in the log saying : “WARNING - PATHS MAY NOT BE VALID” which seems to suggest that my NavMesh volume is missing and yet it’s there. See below:

  1. When I play it in the editor and view the behavior tree I see some red lines next to a couple of the nodes but I cannot find any error in the output or message logs. When I hover my mouse over the first Blackboard node in the sequence it says: “value: AI_Character_12 (fail)”. Hovering over the CloseEnough node just says “CloseEnough” See below:

Any help is appreciated. Thanks.

I just finished implementing this tutorial, and its a tricky one. I think the red bars on the side of the nodes are there just to show if the conditional is returning true or false. Judging by your last image, it looks like your “CloseEnough” decorator is returning false, thus, preventing your task “RapidMoveTo” from executing.
