Ok, so... trying to add a random tree/rock generator to the game, we stumbled into some problems...
Essentially, the generator was based on arrays, while the game didn't use arrays to store the tiles.
After that, we decided to re-write the game from scratch, using a bidimensional array to define which tiles are created in the game world, instead of using whichever method was used before.
On the other hand, arrays will make the creation of MicroWorld easier. So, when we have completed the terrain generator, we will focus on adding content to the gameplay, such as animals, mining and so on...
Take your time.Good work;)
