Here is the article 9 about my series of posts about the game creation.

Maze generation

So now we have the moving character, we will have to close some doors to create a real maze.

To do that, i used this simple algorithm:

1. Identify all cells as "not used"
2. Current cell is 0,0
3. Randomly choose a neighbor-cell which is not already used, and mark it as connected to the cell 0,0
4. Current cell is the new connected cell
5. Go to step 3 until no more "non-used" neighbor-cell found

In the image bellow, those are the cells connected from 1 to 7. The cells 8/9/10 are not connected right now.

When there is no more "non-used" cells close to the current cell, we will have to connect all non connected cells to the path created.

1. Pickup a "non-used" cell
2. Connect it to a near-connected cell (if one is present)

After creating the maze, we have to randomly pick 2 cells for the start and end positions:

Here is the final result:
