In this sample we have modeled some buildings ans tile grounds and put it together in Unity to make some prefabs. We remove the tile with pattern 0-0-0-0 to reduce the connection-0 sides.
Tip: The algorithm search the new tile from only two previous tiles, then you only need to have at least some tile with pattern 0-0-X-X to fill this case
If you forget some pattern the execution will display the next message with the needed pattern
It say that you need a tile with two side without connections, make one and add it to the World tile list
This sample is only to show you than Tile City Generator can work with n-connection tiles.
This script generates all posible border pattern and make 1 tile for each of them
