"Elder Scrolls: Arena" Style Movement

Unity Engine

Hey guys!
I’m working on making a “Arena-like” game. Still learning Unity and I’ve hit a small snag.
I’m trying to code the mouse to react like it does in Arena, but not quite sure where I should start.
What it should do is, whenever the mouse nears the edge of the players view area it should change to allow turning at the upper left and right, strafing at the bottom left and right, and walking forward and backward at the center of the top and bottom areas, while remaining a simple target/interaction cursor while not in any of those areas. :confused:

Any ideas on what I can try?

For those who have never played:

if(Input.mousePosition.x < 10) tells you the cursor is near the left screen. but be carefull with different resolutions so dont use fixed values like 1014 for the right side but Screen.width - 10 for example to not get problems when you change resolution one time.

for the action you could use a state machine and set in the function you check the mouse cursor to a certain action (left, foward, interact) and execute the apropriate function when user clicks (delegate).
