Question about character movement


I’m trying to make a PlayStation 1 type of game where the input controls are on the DPAD and your character can only move forward, backward, left, right and jump.
On UDK currently I have my model imported and it’s playable with a third person camera but it moves around using the mouse and keyboard.

Is it possible for me to disable the mouse/keyboard movement and change it to just forward, backward, left, right and diagonal movement?

A great example of the result I want would be in the old Crash Bandicoot games (


I have just remembered this forum is for UE4 and not UDK but if anyone has any help none the less could you please reply anyway?
