Need Some Help With UE4

[matto97]

Ok so im mostly a noob with UE4 but currently i have an enemy character that runs from point to point, i used the AIStops tutorial from UE4. thats what i have in there atm http://puu.sh/q7URh/4c9d4e0ab4.png
now the character runs along this and when he sees the Player with Line of Sight he then starts to chase the Player. This is the Blue Print for the Enemy http://puu.sh/q7UTQ/36c69b1ad0.png

 

Now what i want but dont know how to do is set it so the Enemy doesn't run from point to point but walks, and when he spots the Player to then start running. But if he looses sight or gets to far from the player i want him to go back to the path to patrol again and start walking.
But im not to sure on how to do that with my current set up, i did find some tutorials for the things i have described but me having very little knowledge i didn't know hot to translate them to work with my set up.
Also tried asking on the Unreal Forums..... day 3 still no reply.

So wold love your help on this guys thanks.
