AI MoveTo Fails, Character Doesn't Move

Hi there,

I’m currently trying to get an AI character to move towards the player character when in range. I had this working previously by following this tutorial:

https://docs.unrealengine.com/latest/INT/Engine/AI/BehaviorTrees/QuickStart/index.html

Currently the target actor and target location appear like they’re being set properly, but when the behaviour tree gets to the AI MoveTo node in the blueprint below, it fails every time.

Things I’ve tried: building the level/paths, moving AI character and nav mesh to different surface, creating new AI character using default walking/collision values

Any guidance would be appreciated. Let me know if you need more info.

This was a bug in 4.13, they said it would be fixed in 4.13.1 but it’s not. So don’t worry it’s not your code.

You can either revert to 4.12.5 or wait it out. Not sure if there’s a workaround for AI Move To

Thank you so much! I was working on that for days and getting so frustrated. It’s nice to know I’m not just missing something.

Luckily I had noticed my AI stop working on upgrade from 4.12.5… Must have been horrible thinking you were doing something wrong :frowning: Someone on the forums has posted a workaround (I haven’t tried it yet) UE-35852 AI Move To Location zeros velocity each call NOT FIXED! - Feedback for Unreal Engine team - Unreal Engine Forums!
