Methods:

isOpaqueCube = Controls whether a neighbor block sides render. Use should return false for any block that isn't a true 1 x 1 x 1 otherwise blocks touching this block won't render its sides.

getLightOpacity = Each block has an Opacity value ( .getLightOpacity() ), which determines how much light it receives from its six neighbours. A low opacity (eg 1) means the light level decreases by 1 from its brightest neighbour, higher opacity (eg 3) leads to a correspondingly larger decrease. This calculation is performed separately for both the Sky Light and the Block Light.
