GetChildGrid(Cell)

The grid associated with each chunk. This grid has extra requirements:

  • It should only use the x-coordinate of the cell. The other two should be zero, (to be offset by the chunk position)
  • The dest of moves is also offset by the chunk position. Moves may be off grid (illegal in a normal grid)

As building a grid with off-grid moves is difficult, you can also just override TryMove to whatever.
