First Person Shooter AI Blueprint tutorial for 4.12.5? Really Struggling

So i have tried almost every blueprint tutorial i can get my hands on to try and get mu AI Character to wander round and then spot me and run towards me, however cant seem to find any in the version 4.12.5, im really struggling and I have a coursework deadline next month, can anyone help me out or know a tutorial for 4.12.5 covering AI in first person? ive imported the character from the 3rd person BP and attatched the animation blueprint to it, Nav Mesh is also placed on my map.

Kindest Regards, .
