❔ I have a basic structuring issue

this is unity but it doesn't really matter for the sake of this I have a character which can move around and look around, but sometimes the movement changes and the mouse movements might be menus so I have a main class and an array of possible active classes for controlling movement, and another array for controling viewing, along with a variable for the current one of each. Sometimes the movement class has to get information from the viewing class, how should i structure this i think that having a reference between the two will make it bad, I am not sure honestly, and I am not sure with the rest of the structure

❔ How do I refactor this?

I am working with a grid of tiles, each tile has an int, which is made up of 4 bytes which represent what value in an enum each side of the tile is in. This means I have a lot of things that need to run after a few calculations are done in a loop of adjacent tiles here is most of the repeated code

for (int i = 0; i < Adjacency.Length; i++)
{
  Vector2Int curr = Adjacency[i];
                
  Vector2Int position = curr + _tile;
                
  if (position.x >= width || position.y >= height || position.x < 0 || position.y < 0)
    continue;

  byte adjacentTileType = (byte)(_tiledata & (byte.MaxValue << (i * 8)));
                
  int oppositeSide = i + 2;
  oppositeSide = oppositeSide > 3 ? oppositeSide - 4 : oppositeSide;

  uint shiftedAdjacentTile = (uint)((int)adjacentTileType << (oppositeSide * 8));
  uint shiftedMask = (uint)(byte.MaxValue << (oppositeSide * 8));
                
  // one function would have stuff to update tiles based on these calculations, another to check if they are valid, some other ones will be added 
}

for (int i = 0; i < Adjacency.Length; i++)
{
  Vector2Int curr = Adjacency[i];
                
  Vector2Int position = curr + _tile;
                
  if (position.x >= width || position.y >= height || position.x < 0 || position.y < 0)
    continue;

  byte adjacentTileType = (byte)(_tiledata & (byte.MaxValue << (i * 8)));
                
  int oppositeSide = i + 2;
  oppositeSide = oppositeSide > 3 ? oppositeSide - 4 : oppositeSide;

  uint shiftedAdjacentTile = (uint)((int)adjacentTileType << (oppositeSide * 8));
  uint shiftedMask = (uint)(byte.MaxValue << (oppositeSide * 8));
                
  // one function would have stuff to update tiles based on these calculations, another to check if they are valid, some other ones will be added 
}

This seems like a problem that would be solved with a functional language, but how would I allow for a few functions reuse this portion of code, adding a new bit on the end without copying and pasting all the starting stuff

❔ How Would I extract a single byte from an int

In my project, I have information which is effectively a byte[4] stored in an int32, I want to grab a specific byte from this I currently have the code

byte adjacentTileType = _tiledata >> (i * 8);

byte adjacentTileType = _tiledata >> (i * 8);

this produces an error as it should, but how would I do this properly
