Legend of Zelda

Zelda Game written in Java (W.I.P)

The game loop:

The State system:

My program reads comma-seperated text files and outputs a map using the following function:

mapLoad(x, y):

load file(x + y + ".txt")

for i in cols:
  read and split and store in nums
  for j in rows:
    temp = nums[j]
    # rows * i + j is a formula that can tread 1D array as 2D array
    tiles[rows * i + j]
    
    rectangle_tiles[rows * i + j] = new rectangle(j * width, i * height + shift, width, height

Where can Zelda walk?

if not grass:
  walkable[16 * i + j] = true
else:
  walkable[16 * i + j] = false
