[212376-help.png] Was following a tutorial for getting an AI enemy to use a behavior tree. The screen shot is from said tutorial which was done in an earlier version. I’m guessing since I am using 4.17 this part has changed. Any help very much welcomed.

That is now a pure function. It can be called from inside a pawn. [212377-ue-answerpic35a.png] Though, I suggest for you to put that code in your AIController. Then just call Run Behavior Tree.

Right I was able to find those nodes just don’t know how to go about recreating the image I posted. I am still fairly new to UE4 and blueprints in general so a little more guidance is needed.

White lines represent to execution flow, they go from one task to the next. Other colors represent variable data. Drag the white pin from Begin Play, directly into Run Behavior Tree. Then drag the Return Value pin directly from the Get AI Controller node, into the Target input.

What does the blackboard look like?

If you debug the blackboard, does it run?

How would I go about doing that? I looked up debugging the black board but didn’t get much…

Open the black board in a separate window Start the game Press ~ to open console and make sure in the separate window , that at the top you have an blackboard instance selected to debug Now you should see the execution if it was setup right

Press ~ to open console and make sure in the separate window , that at the top you have an blackboard instance selected to debug Not sure what you mean there… [212461-screenshot-1.jpg]
