Character Random Movement

Hello everyone

I got a problem with my assignment. I want to make my character moves randomly that is character will base on random numbers(for example generate 4 random numbers) and character’s favorite(for example fast food, west food, Chinese food) to move. The character will move randomly with 4 direction that is move up, move down, move right and move left(any speed will do). Should i have four function with four movement.

Any ideas?:jail:
