How to notify AI if it is stuck

Need some help with AI. So maybe someone can help me. What is the best way to tell NPC change state at behaviour tree if it cannot reach target location ( I’m using move to) For instance NPC Just blocked by static mesh and I want to break current task and make something else? I’ve tried to use time limits for tasks but this seems to be not the best solution.

Did you ever find out a good answer to your question?

Either set the objects in your level with “can ever affect navigation”


check if the path “is valid”

You can check last update is zero then it is stuck

How would you do this? Can you show a blueprint example?

you can get it from character movement
