Physics System

How It Works

The Physics System consists of a whole bunch of checks (if Statements) to see if an tile should or should not move in a direction. However, to optimize the physics system all modifications are stored into lists which get applied after all calculations are done, which means each tile has to check multiple lists to make sure that they won’t cause any issues (such as tiles being overwritten).

// Move Tile Down
if (!IsTileAtPosition(new Vector3Int(x, y - 1, 0)) &&
    !positions.Contains(new Vector3Int(x, y, 0))&&
    !positions.Contains(new Vector3Int(x, y - 1, 0)))
{
    if (nullPositions.Contains(new Vector3Int(x, y - 1, 0)))
        nullPositions.Remove(new Vector3Int(x, y - 1, 0));
    nullPositions.Add(new Vector3Int(x, y, 0));
    positions.Add(new Vector3Int(x, y - 1, 0));
    tileArray.Add(tile.tile);
       
}

Adding Your Own Physics Tiles

If you are wanting to add your own water or sand like tiles to the game, I recommend adding your tile name to the existing code.

// Old Check
if (tile.id == "Water")

// New Check
if (tile.id == "Water" || tile.id == "Example")

Alternatively, if you are wanting to create your own custom physics you can use one of the provided examples to base your own code off.
