Blackboard Key Problem

Development Programming & Scripting Blueprint
1

So I’ve been working on an AI Monster that moves to a single point and investigates a noise, and I’ve encountered a problem, when creating a behaviour tree, I set a simple “move to” task node, but the node defaults to using the unset Investigate vector, and won’t let me set the Target point even though it was created in the blackboard first.

Anyone know how to get around this?

Edit: New Development, when I set the Node to none and close it down and re-open it, it says that its set to the MonsterTarget, but the moment I click on the WalkTo node, it switches back to InvestigatePosition, if I do not click on the node the AI still does not move to the target location

Use this, works in 4.6 and 4.7, part one of a few.

That’s actually the exact tutorial before the one I was following when I first encountered my problem, he doesn’t have this issue

Ok, I have a vague memory he does something on screen and does not say it.

I followed the way to damage/animation when I lost it.

It works, trust me. I got a AI bot running. You like me missed something.

I will upload a video up to attack animation.

I copied the tutorial again and its working now, still not sure what I missed but it is working, however it does still switch to the vector automatically still when I click on the task node, so I’ll just have to not touch it until I’m sure what I need, but thanks for the advice

I’ve figured it out, the basic problem was that in the blackboard any I was making a key, I wasn’t setting it to Actor, so the tasks weren’t picking them up
