Code:

One block of dirt next to supported stone.

What shall happen with the dirt next to the stone - will it fall?

Code:

Three Blocks of dirt next to supported stone - will definitely fall.

Or will only this 'configuration' fall?

Code:

Dirt on stone, further away from actual supporting column.

And what about this? Will that one block fall or not?

I need to know because that is a crucial point in calculating block stability.

If dirt falls in the first scenario, but not in the third... things will get a little tiny bit more complicated.



Ath the moment, block stability is calculated expecting both the first and the third case to fall.
Take a look at this.

Orange being dirt, blue is rock/stone and pink is gem. Grey is nothing.
Numbers indicate calculated stability - 3 meaning fully supported, 2 is one field away from a fully supported block and 1 is two fields away - 0 means that a block will fall (if there is a block). A rock block connected to another rock block has a minimum stability of 1 if the other block has a stability greater than zero.
This means, if there was a block directly above the rock with a 3, it would be fully supported - a block next to it would only have a stability level of 2. The rest is as depicted in that image.



Also, no, it does not do anything but drawing some colored rectangles with numbers yet.
