I've a space game with tilemap that looks like this (simplified):
Map view - from top (like in SimCity 1)
0 - room space, 1 - some kind of wall, 8 - "lock" beetween rooms
public int[,] _layer = new int[,]
{
{ 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 1, 1, 8, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 0, 1, 0, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 0, 1, 0, 8, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 0, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
};
Each tile contains Air property (100 = air, 0 = vacuum).
I made a little helper method to take tiles near tile with vacuum (to "suck air"):
Point[] GetNearCells(Point cell, int distance = 1, bool diag = false)
{
Point topCell = new Point(cell.X, cell.Y - distance);
Point botCell = new Point(cell.X, cell.Y + distance);
Point leftCell = new Point(cell.X - distance, cell.Y);
Point rightCell = new Point(cell.X + distance, cell.Y);
if (diag)
{
return new[] { topCell, botCell, leftCell, rightCell };
}
Point topLeftCell = new Point(cell.X - distance, cell.Y - distance);
Point topRightCell = new Point(cell.X + distance, cell.Y + distance);
Point botLeftCell = new Point(cell.X - distance, cell.Y - distance);
Point botRightCell = new Point(cell.X - distance, cell.Y - distance);
return new[] { topCell, botCell, leftCell, rightCell, topLeftCell, topRightCell, botLeftCell, botRightCell };
}
What is the best practice to fill rooms with vacuum (decrease air) from some point?
Should i use some kind of water flow?
Thank you for any help!
