How is the mining speed of blocks determined?
I thought it was just based off the hardness, the harvestlevel, and the harvesttool. But I guess not because I noticed today:
Cobblestone-> hardness: 2, harvest level: 0, harvest tool: pickaxe, harvest time: 10 seconds by hand
Wood Planks-> hardness: 2, harvest level: 0, harvest tool: axe, harvest time: 3 seconds by hand
So there is obviously something more than just those 3 values...
