Quote from Pokeyletsplays
i like the idea but there is a flaw in your plan
the only way i can see doing this is overwriting stone to make it affected by gravity in a way
i attempted that once but when generating a world the game would crash because of how much stone is in the world and how much caves are there also so there would be over 10000 falling blocks at the same time when generating the world so... you can do the rest of the math i'm sure
HINT: it ends in a crash
But no matter good idea non the less
There would be a way around this.
Just make it only falls under certain circumstances, like the player making too much noise without support beams around.
