AI Character not moving / reacting

Development Programming & Scripting AI

Hi Guys,

I followed the UE tutorial here:
https://docs.unrealengine.com/latest/INT/Engine/AI/BehaviorTrees/QuickStart/14/index.html

in order to learn how to make an AI blueprint and have the AI Character follow my TopDownCharacter around. However, after wiring everything up (which I’m 95% certain I did accurately) the AI_Character does not move. He simply stands there. I literally don’t even know where to start to troubleshoot this. The blueprints I literally copy/pasted from the docs right in to the blueprint map and everything mapped perfectly and compiles with no errors.

Here is the link to the Dropbox folder if someone wouldn’t mind taking a look:

Hey Fexception,

Could it be that you don’t have a navmesh in your level, the AI needs this navmesh to move around.

Hope this helps :slight_smile:

Or maybe you didn’t link the AI :wink:

A good description would be, that he even doesn’t fall down when placed in sky.

Dont just copy the examples, this es where error come from

I didn’t have that set earlier, you’re right. I did set it and for some reason the character still didn’t move. But that was because I misunderstood what the project is supposed to do. The AI is supposed to go to the area where I was last seen, not follow me around like I expected. After going in to his line of sight and hiding behind a cube, he would run to that location and then run back. Though the AI is a little odd, I think I have a starting point for understanding this whole system. Thanks!
