Help AI driving me crazy

according to this tutorial:

I am supposed to used follower_AI_CON_C, however I cannot find that anywhere…is that supposed to be AIcontroller or something else? Please help.

Yep, this is AIController which you create in previous step. For creating ai controller in Create blueprint class dialog in all classes type AIController and select one.

okay so I got that part, now for the diagram on the tutorial, how do I find alot of that stuff…I am a beginner…not very familiar with this…is there a beginner AI tutorial?

Ah figured it all out…only node I need is the one that the AI_CON_REF in the greyed out box at the beginning on the left of the blue print image…it connects the Branch node…where can I find that and what is that?

what is this blueprint node in other words…?
