Okay, this is a big update for me. I added:
Player collision ( based on where you head is).
Walking using thumbstick/touchpad.
Snap Turning ( still isn't best, there is a one bug i found while recording).
Walking on Slops and Stairs ( didn't showed the slops movement in the video)
had System which don't allow peaking inside objects/walls.
there is a system allows you to reach over to pick up objects ( didn't show it in the video).
And this it, pretty much. ofcouse i didnt write it out of my head in few days, i worked with one tutroil and other user on Unreal forums to figure it out. Snap Turning was the biggest issue as i just dont know enough about Unreal. the soluition was very simple, just a thing a miss while writing the blueprint of it.
