See what I want to say on my youtube video
In this situation, i programed each condition of terrain.
Have a way to make this more easy?
If have a grass block, and I click on it, its will become a circular dirt block.
If have a Dirt block, and I click on the side block, both will become a "U" dirt block.
And so on.
And I have a "T" Block, for two diferent path, "X" block to three and "L" block for curve.
