I mostly just worked on getting my map generator working today. While I like the maps it makes there are some leftover artifacts from the generation method and the code is currently slower than I want it but for the first map generator I have ever made it does incredibly well. I also have my bit of code that makes a text file of the map still in so I can continue to test it and see exactly what is going on.

this.Height = Height;
this.Width = Width;
this.tile = new Tile[Width, Height];
}
}
class Tile
{
public bool Walkable;
public bool Seethrough;
public bool Room_Wall;
public char Symbol;
public Tile(bool Walkable, bool Seethrough, bool Room_Wall, char Symbol)
{
this.Walkable = Walkable;
this.Seethrough = Seethrough;
this.Room_Wall = Room_Wall;
this.Symbol = Symbol;
}

I spent most of my time working on it trying to get placement working right till I figured out I needed to store all of the rooms instead not. I finally figured it out and decided on using a list which works out quite well for what I needed.
The other thing that took a while was cutting features. I originally was going to have water and lava tiles but I ended up tossing that for this game because I had enough on my hands with just generating a regular map. I still need to add doors to it but this was a purposeful choice to not include it here. The way I have it planned I will need to add them later but that will be easy because I will only need to look for map tiles that are both using the '.' character and have Room_Wall as true.
