Randomized metroidvania 02: map connections

The rooms are now connected! I used a very simple method that's guaranteed to connect and will even create loops to join different "branches" that happen to be near by.




to connect a room:
    after placing a room
    get a list of all adjacent cells that are in a room
    randomly pick some cells to create doors

This can create multiple opening between two rooms. That's not a problem yet but it could be tweaked later on. This should be enough to create the gameplay portion but I'd like to work on defining different regions at the world-gen level before I move on to creating a player to run around.

  1. Thanks once again for sharing this! Your solutions are so elegant in their simplicity.

    Will you be showing any sample code excerpts for this "Metroidvania" series?

  2. @KC, I may show some code but probably not. I do plan on describing the algorithms I use though.

  3. I was wondering, how are you storing the connection points? Are you flagging cells? Holding a list of all exits from a room in the room?

    I'm sort of delighted and disappointed you don't have any source code posted. I have everything up through regions done, except the doors.

  4. @Dhinanta, At this point, the world is just a list of rooms and a list of doors. Each room also a references to it's doors. I've also tired this with a 2d array of screen-sized tiles where each tile had 4 sides that were WALL, OPEN, or DOOR. That also works well.
